I have a Hayward Super Pump Model # SP2610X15. The outgoing connection which sits at the top of the pump had a leak, I took it off and re taped it and set it back in. Still leaking, I found it had a crack on the inside along the threads. I bought a new replacement compression fitting which says it replaces Hayward SP 1485DA and put Teflon tape on it and installed it. Now it still has a small leak but is better then before. I'm thinking it should have either a gasket at the top where it meets the pump body or an O ring at the bottom because it sits pretty flush with the housing. Is this possible?? or do I need to just snug it up a little more.
