What Causes AC Valve Leaks—and How Can Chino Technicians Fix Them?

Ever noticed your sprinkler system running even when it shouldn’t be? Or maybe you've found a puddle forming near a valve box that just won’t dry out? Yep, you're likely dealing with an AC valve leak.

 

At The Sprinkler Repair Company, we’ve seen our fair share of leaky valves, and we know how frustrating it can be. That’s why we specialize in AC valve leak repair in Chino—so your yard doesn’t turn into a swamp and your water bill doesn’t shoot through the roof.

 

Let’s be honest—leaky sprinkler valves might seem like no big deal at first. But left unchecked, they waste water, drive up your utility bills, and can even damage your lawn, plants, and system components over time. Most homeowners in Chino don’t realize there's an issue until it's already caused serious water loss. That’s where we come in. We understand how important your irrigation system is to your home’s curb appeal and your peace of mind.

 

Valve Gone Bad? Here's What’s Really Happening

 

There are several reasons why your AC valve might start leaking. Let’s break it down:

 

1. Worn Out Diaphragms: Over time, the rubber diaphragm inside the valve can wear out or tear, leading to constant water flow—even when the valve is supposed to be off.
2. Cracked Solenoids or Valve Bodies: Exposure to sun, wear and tear, or freezing weather can cause the valve body or solenoid to crack. This allows water to escape constantly.
3. Dirt and Debris: Dirt gets into everything—including your valves. Just a tiny bit of debris can keep the diaphragm from sealing properly.
4. Improper Installation: If a valve wasn’t installed right in the first place, you're gonna run into issues sooner than later. We’ve seen it way too often.
