Local Story: Leaking PEX Pipe off Bushard and Talbert
One evening, we got a call from a homeowner near Bushard and Talbert. He found water bubbling up from a baseboard corner. At first, he thought it was a slab leak, but we traced it to a PEX joint behind the drywall.
Turns out, the pipe was exposed to sun through an attic vent—a small piece of pipe left visible. UV light had weakened the pipe over time until it finally cracked. This part of Fountain Valley originally had copper, so the PEX in this home was from a reroute done years ago—and whoever did it didn’t bury the pipe properly or shield it from sunlight.
Because we’ve worked in so many homes nearby, we knew how to access the wall cavity without damaging the finish. We replaced the damaged section, re-insulated the space, and checked for other weak spots. All done in one visit.
What Can Go Wrong with PEX in Fountain Valley Homes?
PEX is tough, but it’s not bulletproof. These are the problems we see most:
- UV exposure causing pipe brittleness (especially in attics)
- Poor crimping or fitting mistakes during install
- Excessive bending stress causing micro-tears
- Damage from rodents or pests chewing lines
- Water hammer or pressure surges weakening joints
We use infrared moisture detection and high-tech ultrasonic listening tools to locate the issue—fast and without tearing your place apart.
Common DIY PEX Repair Mistakes We Fix in Fountain Valley
We’ve fixed plenty of home PEX patches that weren’t done right. Some homeowners use the wrong crimp ring size or skip the insert stiffeners altogether. We’ve also seen folks melt the pipe ends using heat instead of proper expansion tools.
One guy even used a hose clamp and silicone to seal a leak—didn’t last the night.
Another issue we run into is folks not knowing what type of PEX they have. There’s PEX-A, B, and C—and they don’t all use the same fittings. PEX-A might need expansion rings, while PEX-B usually takes crimp or clamp tools. If you use the wrong fitting or skip a step, it’ll likely leak again.
PEX repairs look simple, but there’s more to them than meets the eye. Call us if you’re not sure. Sometimes our job isn’t just to fix something—it’s to help our neighbors make better decisions and feel confident in their home.
