I have had the booster now working since January with no problems. Came out today and there is a considerable amount of water leaking from the top 1 1/2 inch connection.
Searched the forum and found the info on the O-ring. Purchased a new o-ring. Installed with plumbers silicone lube. Hand tightened. Still leaked.
Checked the plastics. No crack. Water definitely not from coupling with PVC as the water is coming up nut.
Tightened a bit more with strap wrench, no help. Slight movement changed the flow from the leak. Tried the blue stuff out of desperation even though many posts said not to use. I figured it was screwed up already....
Called Hayward and they are sending me out another union, but I hate to redo the plumbing if that is not the problem. They told me to call out a service person. I was tempted, but as I did the work myself, I did not want to deal with the discussion about where I purchased etc. I told the Hayward rep I put it in and he said he could just send me the part...
Is this a job of exclusion? It seems like it. If I do the plumbing and put the new union on and there is still a leak, I assume it is the housing? Does not make sense that the housing would just crack?
This sort of stuff drives me nuts as it is the summer (no freezing) and I don't think anyone hit or moved the pump. I doubt the yard guys touched it as it is not where there is grass. What happens when the professionals get a call with this sort of problem? Any suggestions?
