4 Tips for Retrofitting and
Upgrading Irrigation Systems
Winterization season is a great time to evaluate your customers’ irrigation systems and suggest retrofitting or upgrading outdated equipment and software for the coming year.
Irrigation technology is continually advancing as sustainability and water efficiency become increasingly important. As a result, the opportunity to enhance sales by retrofitting and upgrading current systems is huge.

In the past, irrigation systems were upgraded only when they ceased functioning properly. Not so anymore. Today customers may want to augment their existing system with water-efficient controllers or other solutions. They’re seeking out smart controllers and nozzles that use less water and prevent runoff. And they want the convenience of mobile connectivity.
4 Tips to Consider
Here are four tips to consider before embarking on an irrigation system upgrade or retrofit:
#1. Familiarize Yourself with the Currently Installed System
Gather as much information as possible from the homeowner regarding the current system. Determine how old the system is and learn about its efficiency and history.
The simplest way to do this is to review the service calls, noting the required repair type (pipe break, broken sprinkler, bad solenoid, etc.). This information will help you identify trends.
#2. Identify If the System Needs an Upgrade or a Retrofit
Is the intention to improve the existing system’s performance (upgrade) or completely replace it (retrofit)? Retrofitting involves both software and hardware modifications, while upgrading focuses solely on software improvements. Knowing this will help you ascertain the level of difficulty the project will entail and the best options for a successful upgrade or retrofit.

For instance, a maturing landscape may interfere with the system’s water distribution. (This is especially true for drip irrigation systems.) You may need to relocate the sprinklers or even install a different type of system altogether. On the other hand, the mature landscape may just require more water; upgrading the controller’s software may be all that’s needed to improve distribution and efficiency.
#3. Determine Budget Constraints
Identify the priorities based on the homeowner’s budget. Your preferred supplier can offer cost-effective upgrades that won’t break the bank. On the other hand, systems that require a complete overhaul can be expensive. If the homeowner does not have the cash on hand for such an expense, financing is a great option. (See sidebar below, “Customer Financing Benefits.”)
#4. Consider How It All Fits Together
How does it all fit together? Are the existing hydraulics powerful enough to water everything in the allotted time? Are the rotor zones using matched precipitation rate nozzles? It’s an easy change and will greatly improve the system uniformity. Additionally, in older systems, nozzles can wear out. This is usually indicated when the water stream from the nozzle is ragged and rough. A worn nozzle will also experience a radius reduction.

How far are your upgrades from the controller? More than 1,100 feet and you may need to run more electrical. Lastly, consider how your customer will be connecting to the controller. Is it through ethernet, cellular, or Wi-Fi? While ethernet is faster and more dependable, Wi-Fi and cellular offer mobile control.
Products for Irrigation Retrofits
Here are a few products and equipment that have retrofit capabilities.
Tucor Hybrid 3D
The Tucor Hybrid 3D is a simple plug-and-play device that allows you to add a master valve, flow sensor, and 1-24 new valves to any irrigation controller using existing wires. It can also convert a conventional controller to a Tucor 2-Wire decoder system. No need to run additional control or communication wires and cables in order to expand the existing system.
Rain Bird Spray-to-Drip Retrofit Kit
Customer Financing Benefits
If your irrigation business is not yet offering customer financing, here are a few reasons to consider it:
Accelerates the Sales Process. Offering flexible financing at the point of sale minimizes pricing objections and helps close deals faster.
Increases Customer Retention. Helping your customer manage his budget and cash flow will create a strong connection that can lead to the next sale.
Delivers a Great Customer Experience. Leveraging customer financing lets you eliminate the sting of sticker shock and shift the conversation away from budget constraints to the value an upgraded irrigation system provides.
Gives Your Business an Edge. Offering customer financing can give you a competitive edge, allowing smaller businesses to compete with larger ones.
Attracts New Customers. Research indicates that the top-performing home improvement contractors offer customer financing. Prospective customers shopping around for an irrigation contractor may be more likely to choose one offering financing options.
This simple kit easily converts each sprinkler head into a 6-port drip emitter watering system. The 1800 Retro internal assembly is easily installed into any existing Rain Bird 1804 spray head bodies to retrofit the current system to Xerigation® products.
Kit includes three) 1 GPH and three 2 GPH drip emitters to allow flow variation, fine mesh filter, 30 PSI pressure regulator, and manifold that connects to 1/4 in. tubing.
Hunter MP Rotators
Hunter’s MP Rotators apply water using heavy droplet streams at a matched precipitation rate. The slower application rate allows water to soak into the soil gently and achieves an even distribution throughout the irrigated area. The MP Rotator can replace the sprinkler head on any conventional spray head body or shrub adapter.
Hunter HCC Retrofit Kit for ICC & ICC2
Hunter also offers a Retrofit Upgrade Kit for its ICC and ICC2 controllers. This kit contains everything needed to upgrade to wifi control using the Hydrawise software — essentially converting the ICC controller to the new HCC controller — including a 3.2″ full-color touchscreen display for Wi-Fi setup, zone testing, and offline programming at the control panel. The Hydawwise software provides easy contractor access to the system via any smartphone.
Baseline Systems BaseStation 3200™
The BaseStation 3200™ supports Baseline’s two-wire technology, as well as conventional wire and retrofit solutions. Its advanced flow management features and flexible communication options allow users to network devices through the cloud or local area networks.
For difficult retrofitting situations or complex irrigation sites, Baseline SubStations can be wirelessly connected to the controller.
Do you offer landscape lighting in your menu of services?
If so, we’re here to help you avoid five common mistakes when installing outdoor lighting systems. Let’s get started!
Mistake #1: Designing with Fixtures Instead of Light
There are a lot of impressive fixtures on the market, and homeowners can easily get carried away trying to incorporate them into their landscapes. But, make sure you’re designing with light and not fixtures.
Decide with the homeowners where they want to have light before you determine which fixture is best for creating the desired effect. Once your customers decide what they want to see and experience at night, you can help them make that vision a reality.
If you’re not designing with light, it’s too easy to use a particular fixture in ways it was never intended. For instance, path lights look great when they’re the right size and properly placed along a walkway. But they look out of place in a flowerbed far from any path.
Focus on the light, not the fixture.
Mistake #2: Using Poor-Quality Fixtures
Outdoor lighting fixtures are made with a number of different materials, most commonly aluminum, composite, copper, stainless steel, and brass.
Getting Into the
Lighting Business
Irrigation and landscape contractors are increasingly expanding their services to include outdoor lighting.
If your business is ready to “switch up,” you’ll want to take some training courses before performing jobs for homeowners. Although no special license or certification is needed, about six to 10 hours of class time should provide you with a basic knowledge of outdoor lighting.
Training is available through your irrigation distributor and lighting vendors such as Kichler, FX Luminaire, and Alliance.
Cast aluminum and composite are less expensive, but they’re lower-quality materials. Over time, it can oxidize, and the paint will fade considerably. (Powder coating can help extend the life of the fixture, but UV rays will cause it to discolor, chip, or peel.) Likewise, composite fixtures will begin to degrade after relatively short exposure to the outdoor elements.
Stainless steel is durable and perfect for a more modern look, but it must be kept clean to prevent corrosion. Dirt, sand, and other materials can compromise its protective layer of chromium oxide.
Brass and copper are both naturally resistant to corrosion. (They will slowly patinate when exposed to the elements, but they will not corrode.) Brass and copper are more expensive, but they’re also the most durable metals. Several manufacturers offer extended warranties on their brass and copper products.
Also be sure to use thicker-gauge wires with waterproof connections and outdoor-rated LED bulbs for a robust lighting system.
Mistake #3: Blinding the Viewer
If you’ve ever been momentarily blinded by lighting while walking along a pathway or around a pool, you know how annoying it can be. This common lighting mistake is easily avoidable. Never install fixtures in a way that exposes the light source to the eye. The resulting direct glare causes visual discomfort and can obscure the viewer’s vision
Always use glare shields on spotlights and flood lights, and position the fixture in a way that allows the shield to block the light source from viewers’ eyes.

Mistake #4: Over-Illuminating
There are two causes of over-illumination: high bulb wattages (e.g., using a 50-watt halogen when a 20-watt would be visually more appealing) and too many fixtures positioned close together. (See sidebar, “Ditch the Runway.”)
Ditch the Runway
To avoid over-illumination on pathways, the experts at Volt Lighting recommend positioning path lights in a zigzag pattern.
Alternating the fixtures from one side to the other, instead of lining them up on both sides, offsets the “airport runway” effect and creates a more aesthetically pleasing landscape.
Also, for curved paths, be sure to position the lights so they follow the curve.
An adequately illuminated residence increases security, but the outdoor lighting installer must always consider the customers’ neighbors and be aware of relevant light pollution codes.
You can’t go wrong by consistently adjusting to the lowest possible light level. The light of a full moon has a light level of only 0.01 lumens per square foot (or foot candle). Most path lights project a level about ten times that, while a typical spotlight projects more than 100 times the level of moonlight.
Use the minimum light level for the most aesthetic lighting that still offers safety and security.
Mistake #5: No Maintenance Plan
The outdoor environment can be brutal. Heat fluctuation, precipitation, dust, insect/animal activity, and plant growth all take their toll on an outdoor lighting system. As a result, all landscape lighting requires a certain amount of upkeep.
Advise your customers of all the benefits of annual maintenance, then follow up with them to schedule an appropriate time to provide this service. Here’s a checklist of standard maintenance tasks:
Remove hard-water deposits from fixture lenses.
Bury any exposed wire.
Trim back obstructive plant growth and/or relocate fixtures.
Use a multimeter to test terminal blocks inside transformers and adjust power loads, if necessary.
Inspect and adjust timers inside the lighting control.
As an irrigation contractor, one of the surest ways to enhance your bottom line – as well as your professional reputation – is to develop a solid and meaningful relationship with your distributor.
If you’re ready to make this partnership a priority, here are a few “don’ts” to keep in mind:
Don’t Be a Stranger
The pandemic showed us how to fall back on virtual meetings and transactions when personal interactions weren’t possible or prudent. Now that we’re moving past that stage, face-to-face meetings should re-emerge as the better way to cultivate mutually beneficial relationships with distributors.
Try to stop in periodically so they can make that personal connection. This conveys a clear message to your distributor that the relationship is important to you.
Keep communication candid and frequent. Suppliers often make decisions based on ongoing conversations with their customers. Create a process so that electronic communications in particular don’t get out of hand.
When Selecting
a Supplier
When first selecting a supply partner, keep in mind the three Ps: products, people and proximity.
Products – Make sure your distributor of choice carries the products and brands you prefer, and offers up-to-date and innovative solutions.
People – Gauge the knowledge level of the supplier’s employees. The staff should be well-informed and understand the challenges contractors face.
Proximity – Is the supplier located within a reasonable distance of your shop or job sites? You don’t want to waste valuable time running back and forth if you encounter a problem.
Along those same lines, be honest with your distributors about the size of your business. Don’t over- or under-sell it. Let them know how often you’ll need materials and what’s most important to achieve your business goals.
Don’t Sound False Alarms
If you sound a false alarm one too many times, you’ll get little to no response. For irrigation contractors, this means try not to expect immediate service from your distributor all the time. Reserve calling in favors for true emergencies.
Remember, your distributor is also juggling multiple priorities. He’s servicing hundreds of customers while also interfacing with manufacturers for required stock. You’ll make his life easier (and strengthen your partnership) if you don’t make every situation a rush request.
Don’t Be Afraid to Negotiate
Both you and your distributor must account for every penny. Once you understand how suppliers set price points, you can negotiate mutually beneficial terms (such as preferred product mix and delivery schedules) as well as costs. While it’s okay to purchase a few items online in the interest of cost savings, remember that solid distributor support will benefit your business more in the long run.
However, expecting a trifecta win of best price, best quality, and best service for every product you purchase from your supplier is unrealistic. Cash discounts and special account terms can be just as valuable as the best pricing, and they provide the added benefit of fostering a win-win relationship with your distributor.
If your business is too small to leverage steep product discounts, consider teaming up with a like-minded contractor so you too can enjoy the type of sales volume that qualifies for a discount.
Lastly, to minimize the risk of misunderstandings, put the result of your negotiations in writing.

Don’t Hesitate to Ask for Help
While it’s important to negotiate your best deal, be sure to ask for help when needed.
Components are continually being redesigned to improve efficiency, and new releases are common. Suppliers are incentivized to stock and promote specific items, so they’ll be glad to hook you up with the latest and greatest products. Don’t hesitate to ask if your distributor offers training for you and your staff.
Occasionally, even highly reputable brands will fail in the field. When that happens to you, make sure your supplier is informed. He’s likely in a position to offer assistance. And if there’s truly an issue with a product, your distributor can go to bat for you with the manufacturer.
More Than Just Dollars and Cents
The makings of a great supplier relationship go well beyond pricing. Of course, you want the best price to get the job done. But professionalism and mutual respect run deeper. Contractors and distributors rely on each other for their very survival.
Prudent professionals on both sides of the counter will work to ensure this valuable association receives the attention it deserves.
Along with July’s intense summer heat comes the prospect of seasonal drought.
In Ohio, we get more than our fair share of 90-degree summer days. These extreme temperatures and dry periods can cause cool-season grasses, such as bluegrass and fescue, to become dormant. That’s when irrigation contractors can expect to receive calls from concerned homeowners.
Have an Education Plan
The prepared contractor has a plan in place to address these customer concerns. You can help alleviate homeowner concerns by educating them on the grass germination and growth process.
Ohio’s Hottest Summer
July 1934 was the hottest month ever recorded in Ohio, setting the following heat records:
Columbus – 106° F
Bowling Green – 107° F
Delaware – 108° F
Cincinnati – 109° F
Findlay – 109° F
Chillicothe – 109° F
Fremont -110° F
Wilmington – 111° F
Hamilton – 111° F
Defiance – 111° F
Gallipolis – 113° F
About 160 Ohioans died of heat-related causes during the week of July 20-26, 1934. More recently, during an extreme heat wave in July 2019, the mercury levels climbed to 112 degrees in northern Ohio.
For instance, explain how different seeds germinate at different times, and the importance of watering longer but less often.
Your customers need to know that dormancy is nature’s defense mechanism to help plants survive tough, stressful conditions. Avoiding it completely during the dog days of summer can be difficult, but there are things they can do to help lessen its impact.
In general, lawns that have gone dormant should be left dormant until cooler weather sets in. Occasional watering will help prevent damage, but don’t overdo it. Overwatering a lawn in an effort to “wake it up,” can be very stressful to the turf.
Inform your customers that bluegrass can typically withstand about six weeks of dormancy before it suffers drought damage. Factors that can accelerate dormancy include secondary heat from buildings or fences, or south-facing slopes.
Seasonal Drought Survival Tips
Provide your customers with these practical tips on how they can mitigate the effects of dormancy on their lawns:
Grow drought-tolerant grasses. Most grasses can withstand some dormancy very well, but some grasses cope better than others. For instance, buffalo grass, fine-leaf or tall fescues, and older varieties of Kentucky bluegrass are the most drought-tolerant species found in Ohio.
Columbus-Area
Watering Restrictions
Several municipalities within the Columbus metro area maintain watering schedules year-round, but particularly during the hottest months. For example:
Westerville – Addresses that end in even numbers can water grass on even-numbered days, and those that end in odd numbers on odd-numbered days. (This restriction does not apply to flowerbeds, trees, shrubs and gardens.
Delaware – During periods of limited rainfall, addresses that end in odd numbers can water on Tuesday, Thursday, and Saturday; even-numbered addresses may water on Wednesday, Friday and Sunday. All watering is prohibited on Mondays.
The communities of Gahanna, Dublin, Hilliard, Upper Arlington, Powell, Bexley, Grandview, and Granville impose similar restrictions during the driest months.
Newly sodded or seeded lawns should not go dormant. Grass must be well established in order to survive a period of drought. Likewise, lawn that has been damaged by disease or insects does not tolerate dormancy well. It is advised that you water the lawn regularly to keep it green.
Keep turf as high as possible by raising the mowing height to 3-4 inches during the hottest time of the year. This allows for deeper root development, and tall grass dries out more slowly than shorter grass.
Understand a dormant lawn’s water needs. A sleeping lawn needs at least half an inch of water every two to three weeks in order to stay alive. If the lawn is receiving that much rainfall, then there is no need to water at all.
Minimize traffic on the lawn. Foot or vehicle traffic can kill the grass and cause bare spots in the lawn.
Once summer passes, thoroughly water the lawn to wake it up. Apply enough water to penetrate the soil down to the root — about six to 12-inches below the ground. After about several weeks of cooler temperatures and adequate precipitation, the lawn will be green once again.
It’s hard to believe, but we’ll soon be heading into July, and you know what that means…Smart Irrigation Month!
Sponsored by the Irrigation Association, this annual initiative is designed to promote the social, economic and environmental benefits of efficient irrigation. This year’s theme is “Proud of our past. Focused on the future.”
Looking Back
First launched in 2005, Smart Irrigation Month has gained traction each year, as various stakeholders recognize the potential impact of efficient irrigation during the hottest summer months and year-round.
Help Ohio Declare
Smart Irrigation Month
Over the past 17 years, many states have declared the month of July to be Smart Irrigation Month, including our neighbors, Indiana and Michigan. Unfortunately, Ohio has yet to join them. You can help change that!
Simply download the IA’s Sample Proclamation, complete it, and email it to your local representative. Promoting Smart Irrigation Month is good for your business and good for Ohio!
In past years, numerous states and municipalities have jumped on the bandwagon to officially declare July as Smart Irrigation Month. (See sidebar.)
Landscape irrigation contractors have taken advantage of this opportunity to differentiate themselves and add value for their customers by promoting water-saving products, practices and services. These businesses report that participating in Smart Irrigation Month campaigns has resulted in new customers and increased sales.
This year’s Smart Irrigation Month is also about focusing on the industry’s future and the many ways efficient irrigation will continue to benefit society through more sustainable landscapes. Here are just a few of the innovations that irrigation professionals can anticipate down the road:
No More Wires
Wireless valves will likely become the norm, particularly for larger installations. Wireless technology will use long-range, low-power, wide area networks. Instead of batteries, inline, turbine-based generators will provide power to supercapacitors.
These wireless valves are expected to include ultrasonic flow sensors that use sound waves to determine the flow velocity within a pipe. This technology can provide very detailed alerts to help technicians and homeowners improve system efficiency.

Droning On
Some of today’s ongoing labor shortage may be alleviated through drone-based irrigation inspections. These drones can be equipped with a bevy of detectors to replicate – and exceed — human sensory capabilities.
Armed with infrared, thermal and acoustical sensors, irrigation drones will fly to each station and locate problems, which will then be pinpointed on a geographic information system (GIS) map. The data will be collected and used to automatically provide suggestions, such as upgrades to components that fail most frequently. This information would then interface with software that can instantly create work orders, pending human review and approval.
Alternate Water Sources
Alternative sources of water for irrigation will likely become increasingly important in the future, especially in areas of water scarcity. These alternate sources could include greywater, rainwater, and even condensate from air conditioning. Onsite tanks can be used to collect, store and filter the water, which is then delivered to highly efficient subsurface drip irrigation piping.
Using A/C condensation will be particularly helpful for the hottest areas and during the hottest months, when condensate quantities are greatest and evapotranspiration is highest.
