Somehow hot water is siphoning out of my water heater from the cold water inlet. I discovered this last summer after I planted grass seed and was watering it in the evening. I went to give my son a bath about 15-20 minutes after I shut the sprinklers off and noticed that there wasn't any hot water. The next evening the same thing happened so I turned the outside hose back on, went inside and felt the cold water inlet into the water heater. The cold pipes were hot!. The water coming out of the hose was not scalding hot, which tells me the water being siphoned out of the water heater is mixing with cold water before it exits the hose. The same thing happens when I was my clothes (I use cold water for everything except for whites). The only way to ensure this doesn't happen is to turn the hot water on before turning on the cold water, then the hot water doesn't siphon out of the heater via the cold line. If I start the washer and I feel the cold inlet going to the water heater is hot and I turn on the hot water at a faucet it barely trickles out of the hot faucet. It seems like there's a vacuum or something..... The TPR valve also leaks from time to time, not sure if this has anything to do with the siphoning issue or if it's just a faulty TPR valve.
To try and remedy this siphoning I installed an inline Heat trap (the kind with a ball), which didn't help. I also y installed an expansion tank thinking that may solve the issue. It didn't..... I'm at a loss as to what could be causing this. The water heater was installed in 2013.
Any help would be greatly appreciated!!!
