Banging Pipes and High Pressure Fixed with a PRV Replacement

That thumping sound your pipes make when you turn on a faucet or flush a toilet? That's called water hammer. And while it might seem like just a nuisance, it's actually a symptom of something worth paying attention to - high or unregulated water pressure hammering through your plumbing system.

Here's what was going on with this home. The pressure reducing valve - the PRV - had failed. A PRV is what sits between the municipal water supply and your home's plumbing, and it keeps incoming pressure at a safe, consistent level. When it stops working, pressure can spike and fluctuate, and that's when pipes start banging and fixtures start wearing out faster than they should.

We pulled the old unit and installed a new Watts PRV, which is one of the most trusted names in pressure regulation. The new valve is rated for a wide pressure range and is properly tagged and ready to go. Everything was tied in cleanly alongside the existing copper supply line and shutoff hardware.

The fix here wasn't complicated, but it mattered. Unchecked water pressure can quietly cause damage over time - to washers, seals, water heaters, and even the pipes themselves. Replacing a failed PRV is one of the more straightforward ways to protect a home's entire plumbing system from that kind of slow, cumulative wear.

If your pipes are knocking, your water pressure feels too strong, or your fixtures are wearing out sooner than expected, it's worth having someone take a look. A failed PRV is a common culprit, and it's a repair that pays for itself in protection.
