gas leak?

Timco

I have a small gas leak somewhere. The meter will not hold a stop test for half an hour. Needle moves slightly.

I bought a tiff 8800 gas detector, that works on all gases (flamable) but cannot find any trace of a leak. The house is 1910, and two 3/4 lines go under the slab and come up at the WH and for the kitchen. Could it be leaking under the slab? Don't smell gas anywhere, and detector either. Ideas?

Certainly could

What about charging the line with compressed air and listen ?

You may have to call a company called LeakBusters. They have all the high end equipment to track down even the tinest of leaks.

Good Luck and DON'T give up !

shutoffs

Can you put in more shutoffs. That way you can isolate sections of the line. As you test you open to the next section, if it leak's you at least have an idea of where it's at..

I would look at where the pipe exits the concrete slab. Is the pipe sleeved? or is the concrete tight around it? Could you repipe and then prove that piping true and abandon the old. Is this nat. gas or LP ?

Timco

No sleeves thru the slab. It is nat gas in SLC. May be time to just run a new system , with new valves, and tested true. I sniffed hard around the suspected areas where the old pipe leaves the slab. Nothing. What size copper is good for serving the boiler? Just kidding. I'll use pex. Pulls in real easy.

Parts of your house could end up on the moon

You should abandon the pipe under the slab and run it new. That leak won't get smaller with time.
