If you do go for the pressure test – make sure the pressure meter is pegged at zero before put on, and shows some value above zero when on.
I say that because we were burned by a broken meter… the meter showed a value (the same one the inspectors observed) even when it was disconnected… And, yes, we DID have a leak. It was a PITA to get SDG&E to confirm then get the contractor to fix it.
In other words – pay attention BEFORE the pressure test valve is put on to verify it’s in working order.
We got lucky – we were having a new meter installed (which SDG&E does) and they left the pressure valve there… so we could see it showed pressure when it wasn’t hooked up. We then monitored the meter and with no pilot lights, no draw – saw slow movement over time… a slow leak.
