Hello, My mini-max NT has a leak at the end of the plastic manifold that is adjacent to the in and out pipes. There is a plastic cap sealed onto the end of the manifold that is slowly dripping water. It does not appear to be PVC. I can replace the leaking part for about $90 but I was hoping I might be able to seal the slow leak with some sort of adhesive.

Question, Anyone know what kind of plastic Pentair uses on their heaters and/or what kind of adhesive could be used to seal this leak up?

Thanks!
