Help! My master temp 300 is leaking water from the blower/air exchanger port. The heater is only 2 years old but unfortunately, while out of town this week my water level fell below my skimmer and I don't have a bottom drain. The pump must have ran dry for at least a couple of days. I have a salt system with a check valve to prevent back flow but I don't have one behind the in-line chlorinator. I think the chlorinated water may have flowed in to the heater and sat causing the heater parts to rust. I took the access panes off and opened the combustion chamber but I'm not certain where the leak is coming from. My guess would be the heat exchanger.
I'm considering changing the exchanger out myself for $600 instead of paying roughly $1000 for someone to do it. Anyone have any thoughts on what may be causing the leak? If it is the exchanger, how difficult is it to replace? I'm mechanically inclined and have no problem working on things. Please, all ideas and suggestions are welcomed.
