If you live in Plano and have an older home, there’s a good chance you may be leaving money on the table when it comes to plumbing upgrades.
The City of Plano currently offers water-conservation rebates for qualifying residential improvements, including high-efficiency toilets and pressure-reducing valves. Depending on your home and the work being performed, those rebates can put hundreds of dollars back onto your City of Plano utility account. Plano
From a plumber’s standpoint, these are the kinds of programs I like because they encourage homeowners to correct real plumbing issues instead of simply replacing something for the sake of upgrading it.
An old toilet that uses too much water or a home running at excessive water pressure can cost you money month after month. If the City is willing to help pay for the improvement, it’s worth knowing whether your house qualifies.
And with Plano residential water and sewer rates increasing effective October 1, 2026, conserving water has become even more valuable. The City says an average resident using 10,000 gallons of water and 7,000 gallons of sewer, along with a standard 95-gallon trash cart, will see an approximately $16 increase in the total monthly utility bill under the new rates.

Here are the Plano plumbing rebates homeowners should know about.
Let’s start with one of the easiest upgrades.
If your Plano home was built in 1994 or earlier, you may qualify for a rebate when replacing older toilets with qualifying WaterSense-labeled high-efficiency toilets.
The City of Plano currently offers:
That means an eligible homeowner could receive up to $225 in utility-bill credits for replacing three qualifying toilets. CivicPlus
There are some important requirements.
The replacement toilet must be a new EPA WaterSense-labeled high-efficiency toilet using 1.28 gallons per flush or less. The homeowner must have a City of Plano water account in good standing, and purchases must be made from a retailer located within Plano. The City also requires the rebate application to be submitted within 120 days of the purchase date. CivicPlus
One nice part of this program is that the toilet does not have to be installed by a licensed plumber to qualify for the rebate. CivicPlus
That said, there are plenty of situations where professional installation makes sense.
If the toilet rocks, the flange is damaged, the shutoff valve doesn’t work, the supply line is deteriorated, or there are signs of previous leakage around the base, I’d rather address those problems correctly while the toilet is already being replaced.
The rebate gets your attention, but the long-term water savings are really the bigger story.
Older toilets can use considerably more water per flush than modern WaterSense models. If you have several people living in the house, those flushes add up every single day.
And sometimes the toilet itself isn’t the only problem.
We routinely see toilets wasting water because of worn flappers, fill valves that never completely shut off, improperly adjusted floats, or water quietly leaking from the tank into the bowl.
A toilet can look perfectly normal from across the bathroom while wasting water around the clock.
If you have an older Plano home with original or older-generation toilets, this rebate is worth looking into.
The rebate I’d really encourage certain Plano homeowners to pay attention to is the Pressure Reducing Valve, or PRV, rebate.
A pressure-reducing valve does exactly what the name suggests: it controls excessive incoming water pressure before that pressure is distributed throughout your home.
The City of Plano currently offers eligible homeowners a rebate equal to 50% of the cost of the PRV, associated parts, and installation, up to a maximum rebate of $500. Sales tax is excluded. CivicPlus
That can be a meaningful savings on a plumbing improvement that may also help protect your home.
People usually think high water pressure is a good thing.
I understand why.
Everybody wants a strong shower.
But there’s a big difference between good usable water pressure and excessive pressure constantly pushing against your plumbing system.
Too much pressure can place additional stress on:
In the field, one of the first things I want to know when a homeowner has repeated supply-line failures, noisy plumbing, or unusually aggressive water flow is what the actual static water pressure is.
You don’t diagnose water pressure by looking at the faucet.
You put a gauge on it and test it.
The PRV rebate isn’t available to every address in Plano.
According to the City’s current application, qualifying properties must have been built before January 1, 2013 and must appear as eligible on Plano’s PRV eligibility map. The program applies to qualifying residential properties such as single-family detached homes, townhouses, duplexes, and condos. CivicPlus
The City’s program is intended for homes in areas where water pressure exceeds 80 PSI according to its eligibility criteria. The PRV needs to reduce pressure to the house—not simply an irrigation system—and the installation must be performed by a licensed plumber registered with the City of Plano. Novus Agenda
That’s an important distinction.
Don’t call a plumber and say, “I heard Plano gives everybody $500 for a PRV.”
First, verify that the property qualifies.
Municipal water systems have to deliver enough pressure to serve homes across different elevations and areas of the city.
That means some lower-elevation areas can experience higher pressure.
Plano has specifically acknowledged that certain older residences in higher-pressure areas may benefit from pressure-reducing valves. The City’s information notes that beginning in 2013, certain new residences in areas above 80 PSI were required to have PRVs, while a rebate program was later established for qualifying older homes. CivicPlus
So if you’re living in an older Plano neighborhood without a PRV, it’s worth checking.
Here’s something homeowners often don’t realize until we’re standing in front of the water heater.
Adding a pressure-reducing valve changes how water pressure behaves inside the plumbing system.
Depending on how the system is configured, an expansion tank or other thermal-expansion protection may also need to be considered at the water heater.
Plano’s current rebate documentation specifically notes that if the PRV installation includes adding expansion tanks at water heaters, a permit application is required before installation. CivicPlus
This is one reason I wouldn’t choose a PRV installer based solely on the cheapest number somebody gives you over the phone.
The plumber should look at the plumbing system as a whole.
Once an eligible PRV installation is completed, the paperwork matters.
Plano currently requires the completed rebate application and an itemized invoice showing the PRV, associated parts, installation, plumber’s license number, and installation date.
The application must be received within 120 days of the PRV installation.
Plano says complete applications generally take about 30 days to process, and approved rebates are applied as a credit to the homeowner’s utility bill. CivicPlus
My advice: don’t put the paperwork in the kitchen drawer and tell yourself you’ll get around to it.
Get it submitted.
The City has also included water-conservation incentives involving irrigation equipment such as qualifying rain/freeze sensors and WaterSense-labeled smart irrigation controllers. Eligibility and program requirements differ from the plumbing rebates, so homeowners should review Plano’s current rebate information before purchasing equipment specifically for the purpose of receiving a rebate. CivicPlus
Plano has offered water-conservation programs for years, and the City can modify or terminate rebate programs. Always check the current requirements before purchasing equipment or scheduling work based on an expected rebate. CivicPlus
From a plumbing standpoint, I’d keep it simple.
If your home was built in 1994 or earlier and still has older toilets, check the high-efficiency toilet program.
If your home was built before 2013, check whether your address is included in Plano’s PRV eligibility area—especially if you’ve experienced unusually high water pressure or repeated problems with plumbing fixtures and supply components.
Don’t replace equipment just to chase a rebate.
Use the rebate to help pay for an improvement that already makes sense for your home.
That’s the difference.
