Good evening all:
I had the pool opened this year (I'm not yet confident enough to open/close myself, so I still rely on the pool company) and it turns out that my multiport is bad AND I had a hole in one of my suction pipes. The hole has been resolved (my pipes are still about 1" below the earth, which I assume is not the best, but...I'll deal with that later as it's, likely, an expensive undertaking and, like most things in my poor house, appears to be a handyman "special" (as in a special pain in my patootie!))
I have two options - (1) replace multiport or (2) replace entire sand filter. I didn't really have any major issues with the filter last year besides wishing it captured pollen and other things better; however, with the suction side leak fixed (I think), the filter/pump seem to be working much better (my rear skimmer is actually showing signs of life).
First, to clarfiy, would a bad multiport/holes in the multiport pipes cause air bubbles in my return? Note that the pipes coming from the filter have holes in the them that are constantly spraying water (we attempted a patch and it failed). When I backwash, my pump runs fine for a few hours and then small bubbles start coming out of one or both of my returns.
Second, should I replace only the multiport for a few hundred or the whole thing for about a thousand (again, relying on others to do the installation)? Is the multiport something I could do myself (note I have ZERO experience with anything plumbing related, etc.)? I don't think I'm ready to tackle installing the filter if that's the route I opt to go.
Any help/advice would be greatly appreciated.
