 Hearing water noise behind bathtub wall
Author: Sweldin (TX)

We own a house built in 1997. Replacing tub spout and handle and I can hear what sounds like water running behind the wall. I checked the water meter and water is running. Thoughts?

Water is going somewhere, maybe the toilet fill valve is constantly running, maybe relief valve on the water heater is leaking. Is the house on a slab ? There is no visible leakage anywhere ?

No leaks evident. House is on a slab. Meter has small triangle shaped arrow. Barely moves. Then stops. Then moves again and stops. Should I open up sheetrock behind tub to look at the piping?

No, I think the problem is in the toilet tank. The flapper is likely leaking thru and the fill valve is just doing it's job of keeping the toilet tank full.

The toilet is not right beaide the tub. It is across from it. But, how do I check toilet? Just open up top right?

put some food coloring in the tank water and leave it for 10-15 minutes. if the colored water shows up in the bowl, replace the flapper.

Since the house is on a slab there's a chance that the cold water for the toilet is tee'd in at the cold water supply for the bathtub, right behind the tub faucet and drain assembly.

Do yourself a favor and determine the make and model of the toilet so you can purchase the correct flapper by Part number. They make so many different flappers and only one will fit properly. The Part Number from the Manufacturer,

Hi:
Thanks for this advice! I put a fits all flapper and I am still hearing the noise. Will check for make and model.
Even with no water in the toilet and the water turned off, I still hear water moving in the wall. I think it is not the toilet.
