Purchased a water heater got it home dented really bad, brought it back and exchanged it for the last one they had, once got it home to found out had to completely cut all plumbing out due to newer models are 2 inches wider. So once all this was done 2 hours later with all new CPVC lines and new flex tubing installed, turned on water to find out this new hot water heater had a leak, so I thought I may have over tightened flex line, so I have to completely drain hot water heater, go purchase another new line and install, once finished to my surprise it leaks also! So started checking and find the bottom of water supply pipe in the hot water heater is damaged causing new flex line O ring to not seal properly so have to drain hot water heater yet again! Drain heater and call store to speak wi
