Hello all,
I just bought a house that has a six gallon secondary water heater in a master bathrom cabinet. The purpose of the heater acording to the original home owner was to allow "instant on" hot water in the shower and sinks of the master bath. Not a bad idea right? Or is it? At the home inspection, we noticed the botom of the heater and the pan in which it sits was a bit rusty. The owner agreed to buy a new replacement heater, I agreed to install it. After i replaced it (which was no picnic. Ever try to drain a tank under a cabinet, when the tank has no drain valve to atach a hose to?) the T&P valve would drip. Mostly when the shower in the master bath is being used. I figure that it was probably always leaking which would account for the condition of the rusty pan and in the original heater. Is this a classic case of thermal expansion? The heater is hooked up like this: The "cold" water going in to the tank is actually coming from the main water heater in the garage. Therfore cold in is actually hot. There is a gate type valve that controls the supply line. Then the output of the heater connects to a copper tube that supplies the bathroom. This is really annoying. I'm considering just looping the lines and geting rid of the heater. Any help or suggestions would be greatly appreciated. Thanks in advance. SK
