Is there a broken hot water pipe under my floor?
The first thing I noticed was warm/hot water coming out of the cold side of my faucets. I checked this site and decided to have the cartridges replaced in my faucets, so 4 out of 5 faucets were done (3 are Moen). The 5th faucet is in a shower stall not being used as a shower, just storage. I have just found out that this 5th faucet (moen) is "frozen" so I should have had the catridge replaced in that as well. However, it is a long shot that this last faucet is causing the problems.
My 1 1/2 yr old gas water heater turns on very often, just about every time I run water. The floor in my kitchen is very warm over about 1/4 of the floor. I live in a 1 level townhome built on a slab, about 30 yrs old. I had the gas company out to check the water heater. The tech says heater okay, and he thinks a hot water pipe under floor is broken. The hot water leaking out warns the cold water pipes laying alongside. This is why I get a one shot of cold water , about 1 minute of warm/hot water and then back to cold water when I turn on any cold water faucet.
I am going to try to find out if my water usage is way up to help determine if there is indeed a leak. Obviously, I don't want to tear up the floor unless I'm pretty sure.
Any thoughts will be very appreciated. Thanks! Gale
