I run my pump for 7 hrs a day using a salt water chlorine generator. I walked out yesterday to find it running dry, and it may have been running dry for a few days.
I have lived here for 4yrs and I've never serviced the pumps in any way.
I'd appreciate some help trouble shooting.
When I fire it up, I hear the motor running and the impeller turning/whining as is usual when priming, though it is a bit more struggling sounding. I get no water movement at the skimmers by the pool, nor output at the returns.
My prime suspect at the moment is the multi valve on the sand filter. One time this Spring it seemed to not engage well after a backwash/rinse, and I had to re-seat it for water to flow. I think the whine of the pump struggling against a closed output is what I am now hearing. So a check of the valve as well as an inspection/maintainance of the pump seem in order. . at least.
Here is my pool as shot from the entry of the pump house:
Here is my plumbing:
If I loosen the band at the blue arrow and slide the motor out of the way, I'll have full access to the wet end for inspection/repair, yes?
I note that the little stainless nipple (at the convergence of the blue/green lines) is missing on the other side. HTis is the point on which the handle pivots when adjusting the valve. I don't know how long it's been this way. It's absence obviously torques the handle/balljoint out of its usual pivot/rotate motion.
So any guidance for a handy but ignorant fellow in need?
The salt water generator I installed has worked like a charm. You should have seen the Rube Goldberg jungle gym that was my plumbing before the install. Much better flow now, too, as a result.
