Hello….had a ROL code on my Raypak 266(13 years old) pool heater a few months ago. A HVAC friend came & cleaned the heat exchanger & replaced the thermal cutoff fuse. Worked great but came home yesterday to water coming from the bottom of the heater. After taking off a few panels, I saw both polymer heads leaking from the bottom seals. They look melted. What would cause this? I took a bunch of pictures just to figure out what happened. Not worth dumping serious money into a 13 year old heater so ordered a new unit. I just want to learn more about what happened to prevent it from happening with my new one….thoughts?
