Agree w LBZYA on pricing. On the orig question...
-turn on gas, smell for leaks inside and out
-verify propane appliances (run furnace (gets gas in the lines quick), hot water heater, stove)
-turn fridge on auto, ensure it fires up on gas
-plug ac power in confirm all ac appliances, (tv, micro, ac, fridge operation, hot water heater)
-verify fridge switches over to ac on its own.
-fill fresh water tank w/a few gallons of water, run water pump, check all faucets (hot water?). Leave pump on. It should only run if a faucet is on (or there us a leak)
-look along the cieling/wall line for soft spots or water stains
-inspect the roof for open joints or tears in the roof membrane
-turn water pump off, connect fresh water hose. Verify flow from faucets.
-disconnect fresh water hose to ensure connector backflow valve works. (Plumbing should hold pressure after disconnect)
