What would be a reasonable cost to have a residential gas system pressure tested downstream from the gas meter. There is a gas furnace, a gas water heater and a gas range on the system.
The piping for residential pressure test shall stand a pressure of not less than three (3) pounds per square inch gauge pressure. The test pressure shall be held for a length of time satisfactory to the administrative authority, but in no case for less than ten (10) minutes with no drop in pressure, using a 15 lb gauge measuring in 1/10 psi increments.
