Hi, I'm home on my own due to husband being out on the road with work and I replaced my motor in my Hayward Northstar SP4010 pump with a 2 speed. The seal was replaced along with the impeller just to give you some background. My strainer lid was leaking water. I got a new o-ring and it still leaked a little but then about 2 weeks ago the union where the pipe goes into the top of the pump housing started leaking. I looked at it and the o-ring is fine, I guess they call that a gasket, no cracks in the nut or anything however the pipe that goes into the housing of the pump isn't threaded or anything and it's not glued in. I tried adding more lube and sealing it and it is still leaking badly. The strainer basket is melted so at some point it must have run dry. Now I need to know what to do to fix and if I can do on my own...
