Yeow! Good thing the utilities are more trusting hereabouts.
Found a gas leak late at night by odor; almost certain was hit by gardener's mower. But had sufficient tools & supplies to section it out, thread the stub, replace the upper length, dope the connections and close with a union. Did have SoCal gas sniff the premises for any other issues. Cheap insurance with raised floor construction.
I'm tending my rental house in CA. Next tenant cares for a challenged young girl, so there were inconveniently arranged [suitable and common for other instances] appliances in the washroom. Aside from re-positioning water supply and drainage, exhaust for dyer and grounded electrics for both in 1941 construction. The gas line fell way short reaching dryer with shortest compact flex line. Once again, a pipe union saved the day with ~7' nestled in a corner, very easy to reach shut-off, and my gas wand detects zero escape of natural gas. No bill for service, less than $70.00 in parts + couple hundred for tools already on hand.
My little house; the one that receives "Oooh, I like this house" from every single person who enters. Even the painters and floor refinisher...
So I won't let just any body take occupancy. Since 1999, the next will only be 3rd to do so. First was 16 years, until their situation required more room.
