Hello I have a pro clear aquatic systems 125 cylinder. I disassembled the union under the tank in the sump housing when Installing the plumbing. Apparently the overflow plumbing was glued at the union and when I separated the union it left hard glue residue and torn bits of the gasket off. I have tried over and over to get it to seal with no luck. I am a loss On Knowing what to do. Does anyone k is what kind of glue I could possibly use. I would just but a new union and flex phone but I can t find where proclear sells these. Any suggestions in what I can do. I am feeling so stupid for taking the union apart. The return side union was not like this.
