Our water use increased by approximately 375 gallons PER DAY about 6 months ago, with no logical explanation.
We have a downstairs guest bathroom where I can hear a hissing noise in the wall behind the toilet. There is no water running into the toilet tank, toilet bowl, or onto the floor. We have also checked under the house in the crawl space and there is no water down there.
If I turn off water to the toilet I can still hear the noise. If I shut off water to the whole house the noise goes away.
The toilet is a Mansfield 160. I’ve replaced the fill valve, flush valve, and tank to bowl gasket with no change.
We have high water pressure, around 80psi when I measured with a gauge on an outdoor hose connection. We have had a problem with knocking noises in the water lines, which has been remedied by adjusting the shut off handle at the water meter (located in the sidewalk in front of the house) to about half way between open and closed. We’ve been in this house for 12 years and have never located any pressure regulators.
My partner went under the house and he said that one of the black pipes (near the toilet and the hissing noise) feels like there is vibration from water running inside the pipe. The crawlspace is very confined (not easy to crawl around down there), and he can’t find any leaks.
What would be your next attempt to find out what’s happening to approx 375 gallons of water that’s disappearing each day? He wants to rip open the drywall behind the toilet, but there is no water damage there or anywhere else.
