Strange Noise in a Crawlspace—But NOT the Hot Water Tank | Doug Cross – Powered by ProQuoteHive

Sometimes the thing making noise in your house isn’t the thing you THINK it is… and this visit proved it. Your HVAC might not be what you think or water heater as well.

I was called out by a homeowner who was convinced his hot water tank was making strange noises from the crawlspace. He was ready to replace the entire unit because the sound had been driving him and his wife crazy. But the moment I got down into that tight space, something didn’t add up.

The tank looked brand new. Clean. Simple setup. No leaks. No overheating. Nothing obvious.

And like a lot of situations in older homes, the noise only happened when no one was looking.

So we waited… and then it happened.

A sharp noise — but clearly NOT from the tank.

After zooming in with my camera and tapping around, I found the real culprit:
A pressure regulator and gauge on the incoming city water line. The pressure was sitting around 100 PSI, and the regulator was chattering every time it tried to control the flow.

The homeowner didn’t need a new tank.
He didn’t need a repair.
He needed someone to look closely enough to find the real problem.

And he saved hundreds of dollars because of it.

This is exactly why so many homeowners feel confused when something “doesn’t sound right” in their house. You hear a noise… you assume the worst… and sometimes the answer is something totally different.
