I posted about a month ago with issues related to a pump that would not prime. We own a inground pool, gunnite with a raised spa and spillover. It's about 9 - 10 years old, and it was here when we bought our home 4 years ago.
It's now been about 2 months since our pool has worked properly. The issue remains that our pump will not start without adding water to get it to prime, and even then it is not reliable. We've had most of the valves replaced, as well as the above ground plumbing. We've had the pump repaired (impeller failed after it ran without water for a while), and the inside portion of the filer replaced. This has cost about $1000. Our pool repair person is pulling his hair out, and told me today that each time he has come out to work on the pool and manages to get the pump started (usually after a period of inactivity of a week or two), he gets a huge gob of dead, smelly worms in the pump basket. It usually fills the basket halfway. This has happened a couple of times, including yesterday.
Unfortunately, the work he did yesterday did not fix the problem. He got the pump started, and I turned it off a couple of hours later. About 6 hours later, my husband tried to start it up (and tried to prime it by adding water) and could not get it going. The pool guy came by again today, claims he got it running, and AGAIN got a huge gob of worms in the pump basket - after only 16 hours of inactivity.
I have two questions. One - what could possibly be wrong with the pool? The pump is fine, by the way.
Two - where are these worms coming from?? Do we have a leak in the underground plumbing? And if that is the case, wouldn't we be seeing dirt/mud rather than simply a gob of dead worms??
Can anyone help me assess this problem? We are at our wits end, and plan to call the company that built our pool tomorrow.
