Problems:
1) Recently my water heater started making a popping noise.
2) And air spews out first when I turn on a hot water faucet.
Possible cause??
* My water has been getting colder recently, so my heating element is going out. I wouldn’t think this would be related. But could it be?
(My line is an ‘open system’ (trailer park), so the thermal expansion should be able to dissipate back into the system. I don’t understand why the pressure is building up!!)
