Does code allow for gas lines under a slab? I would do more
troubleshooting before spending money on a water heater that may not be
the problem. What about ceiling insulation. Is it good? Lots of heat can
go up though the ceiling.

talked to said no way. I'm thinking about replacing the water heater
anyway and see what difference it makes.

As for the gas leak, what if it was underground? I'm on a slab (both
old and new houses) and I've been wondering if a leak under the slab
wouldn't be as detectable.

Another way to check that would be to have a pressure test done.

And to Tom's reply, If it was an estimated bill it would eventually
catch up with me and I'd eventually have a low bill. In living here
2.5 years, I've never had a "low" bill.
