Your water bill keeps climbing, but you’re not using any more water than before. Your water heater gave out years ahead of schedule. A supply line burst under a bathroom sink and you came home to a mess.
Three different problems. One hidden cause — and most Mesquite homeowners have never heard of it.
Your Water Pressure Is Probably Too High
A lot of Mesquite neighborhoods are served by elevated water towers. That gravity-fed system is great for fighting fires, but it can push residential water pressure to 100 PSI or more.
Plumbing code caps safe residential pressure at 80 PSI. At 100 PSI, every fixture, valve, and appliance in your house is under constant stress it wasn’t designed for.
What High Pressure Destroys
Your water bill. High pressure forces more water through every faucet, showerhead, and toilet than they’re rated for. You’re literally paying for water you didn’t need to use.
Your water heater. The tank, the relief valve, and every connection take a beating. We’ve seen heaters fail years early in high-pressure homes — a $1,500+ replacement that didn’t have to happen.
Your supply lines. Those flexible braided lines under your sinks and behind your toilets are the weakest link. At 100 PSI, a burst line isn’t a question of if — it’s when. And “when” usually means thousands in water damage.
Everything else. Dripping faucets that won’t stop dripping. Toilets that run on their own. Dishwasher and washing machine valves failing early. Even voided manufacturer warranties — most appliance warranties require pressure under 80 PSI.
The Fix: A Pressure Reducing Valve (Plus an Expansion Tank)
A pressure reducing valve (PRV) installs on your main water line and holds your home’s pressure at a safe, steady 60–70 PSI — no matter what the tower is pushing.
One important detail: once a PRV goes in, your plumbing becomes a “closed” system, which means you also need a thermal expansion tank on the water heater. That’s code, and it’s included in our installation.
It’s a straightforward job — usually done in a few hours — and it protects everything downstream: the heater, the fixtures, the supply lines, and your water bill.
How to Know If This Is Your House
Here’s the thing: you can’t feel 100 PSI at the faucet. It just feels like “good water pressure.” The damage happens silently, over years.
The fastest way to know: test it. A $15 gauge on a hose bib tells the whole story in two minutes.
