I have a gas hot water heater that, for the last week, has been constantly trying to heat the water (with a normal flame), but I only get warm water throughout the house. There is a slight sound of running water that is loudest behind the shower/tub on the second floor. There is no evidence of water on the ceiling below the shower or anywhere else. When I turn off the water supply to the tank, the sound slowly stops, and the water quickly heats up to normal temp. Each time I need hot water, I must turn on the tank supply, and then off again when finished. The shower-tub control is a Moen 2739A single handle control. Yesterday I replaced the cartridge, thinking that there might be something that was related (It also had a slight drip that is still there with the new cartridge --except when I turn off the water supply to the heater).
Before I tear into the wall behind the tub, is there any other possibility that there is hot water crossing through the Moen apparatus into the cold water pipes? The heater is not dumping through the relief valve, but it is going somewhere after it leaves the tank output line??
If the picture of the Moen parts does not show up, go to this Moen URL and click on "STEP 1: View Illustrated Parts Diagram to find the part you need ".
