Hoping you guys can help. I'll describe the best that I can - I'm not a technician. At the top end of the coiled pvc tubes of the heat exchanger, there is something that looks like a threaded fitting that screws into the coiled pvc. The heat exchanger tube runs through the middle of it. This piece has developed a crack in it and is leaking. The pool store folks said that I have to replace the whole heat exchanger. I find this hard to believe and am looking for more affordable solutions. Any suggestions? Thanks,
