Hot water Leak in slab
Hello, just registered and this is my first post. I have a warm spot under my tile floor that has been there for a few weeks not. I also have noticed that when wwe turn on the hot water in the baths it is like there is an Insta-Hot hooked up. It seems obvious that there must be a leak in the hot water pipe. The pipes from tyhe water heater go up into the attic space, but I am not sure where they drop down.
I just tiled the floors when we moved in in 06. Are there any good alternatives to saw cutting the slab?
Are there ways to determine where exactly the leak is?
Would it help to “buy some time” by shutting off the valve at the water heater when we are not going to be using the hot water, like at night and when we go to work ?
Any advice would be appreciated!
The best way to avoid tearing up the slab is to abandon the pipes in the slab and run all of the water lines through the attic and down through the walls. Do the hot and cold at the same time.
If you have one leak now you will have more later and you will never be done with the leaks.
Do whatever you must for emergencies now since it is costing you a lot of energy to heat the ground under the slab with your water heater. Also, it is conceivable that a lot of water from a big leak could cause more damage.
