Hello. I need some help on a long term solution for a current broken piece in my pool equipment. My bulkhead in the filter area was broken and leaking. I bought a new one, but couldn't get the nut off. The nut on the adapter was stuck on the old broken bulkhead - I needed to get it off. I tried everything I could. Finally, I gave in and sawed it off. I bought a new nut. Once I had the new nut though, I couldn't get it around the bulkhead adapter (black piece in attached pic). Then for whatever reason, I tested the new nut out by screwing it onto the new bulkhead, not in the correct place, and guess what? The new nut got stuck. So, I sawed this one off. The benefit of having it sawed of is that I can get it around the black bulkhead adapter correctly, but in needs the metal clamp to be secure on not leak. The metal clamp is a good temporary solution, but if I buy one final nut, how can I get it around the bulkhead adapter? It looks like the pvc pipes are all connected with glue and I worry about messing up this situation further. Does anybody have any ideas? Thanks so much!
