Question about Pentair Minimax NT Heater
Of course it can be fixed :) The question is, it is worth it? First thing you need to do is find the leak. Inside the heater, where your pool water runs through is called the Heat exchanger. Usually they are made of copper and if the problem is there, it an expensive fix. $800-$1400. The problem could also be a cracked header ( black plastic thats bolted to the heat exchanger) Or just the gasket for the header. If You arent a hands on type of person, I would contact several local pool companies and ask for a free estimate. A Pool service that offers a free estimate is worth doing business with. Make sure more then one company comes out and they both give you the same answer to the problem.
P.s If the problem is infact your heatexchanger, and its not damaged due to ice form the winter you really need to keep a better eye on your water chemistry. A low ph will slowly eat at the copper and once its weak enough the pressure from the water inside will blowout a hole and then, well then you have a leaky heater!

When mine leaked it turned out to be the header gaskets which are made of rubber like a hose gasket the are cheap but not so easy to replace unless you feel confident to disassemble the whole heater. I did it with no prior experience, by just pealing back the layers. first remove the top and body sides, then remove the metal housing with the fan (unplug it all first), then you will be looking at the headers and the core. check to see if it is the front or back header that is leaking, then unbolt it and replace the gaskets. it's not as technical as replacing an automotive head gasket... good luck
