True...and we have had no problem with lack of hot water with this 10 gallon unit. There *is* a problem with the safety valve blowing occasionally and this is the second valve for that heater so the thinking is there is a problem with the thermostat letting the water heat too much. Replacing with even the standard temp sensor might have helped, but I don't anticipate the 130 degree unit I just ordered ($10 ebay) will be noticed.
The Pop OFF valve RARELY fails. What you have is a diminished AIR POCKET
in your Atwood tank. Doug
PRESSURE-TEMPERATURE RELIEF VALVE Weeping or dripping of a pressure-temperature relief valve while the water heater is running DOES NOT mean it is defective. This is normal expansion of water as it is heated in the closed water system of a recreation vehicle. The Atwood water heater tank is designed with an internal air gap at the top of the tank to reduce the possibility of weeping and dripping. In time, the expanding water will absorb this air. To replace the air follow these steps: Step 1: Turn off water heater Step 2: Turn off incoming water supply Step 3: Open the closest hot water faucet in the coach Step 4: Pull handle of pressure-temperature relief valve straight out and allow water to flow until it stops. Step 5: Allow pressure-temperature relief valve to snap shut, turn on water supply and close faucet.
