My pb4sq (1yr old) just started dripping behind the drain plug this week. I open my pool and it worked all good until about 6 weeks now after opening. Now it’s a steady leak about a half inch back behind the plug opening and I have to manually run. Orig I thought it was just an o ring but that seems fine. Seems like it could be a hairline crack. I put some pipe glue on it (blue water based) and it stopped for about an hour but then started back up. Tried a few more times and it just seems to be worse. It’s on auction side which is what confuses me. Do I need to just replace the pump body? Can’t find it anywhere. After a few long calls to Polaris they agreed to send me a housing but in have to have a local pool co install it at labor rates. Anyone know if any other parts would need replaced at same time. Should I just buy a new pentair booster and move on from Polaris? Fearing I’ll spend $250 just getting this back up if I’m lucky after pool co has critiques. I’ve swapped 3 of these pb4’s already in 6 years, plumbing is simple and not worth paying pool co to install but they have me and these things just don’t last. Pics below, anyone have thoughts? It’s getting dirty and I have guests this weekend.
