Sorry this is so long. I have some issues I’m dealing with on my fiberglass pool that is not quite finished but running. I’ll start from the beginning.
After running the pump for awhile the first time, after the pump was shut off I noticed water seeping up from under the pool and water level in my spa drained down to the return jets. My installer thought it could be because he forgot to plug one of the outlets on the skimmer since only one is needed. More on this later.
Also my plumbing had a single 3 HP pump pushing water to the spa and the pool at the same time. The return jets in the spa had enough water flow to fill up and run over the spillway but you could barely feel any flow coming out of one jet and seemed no flow at all in the other 3. So my installer changed the plumbing up separating the spa from the pool and putting a valve that allows me to switch from spa to pool. That made the pressure better but still not like it should be.
we started filling the pool back up, and while he was there had the water going into the spa only, while pump is on. After awhile when the pool level was back to normal I went out switched to the pool to get circulation going. After a bit, water began seeping out from under again. This leads me to believe one of the returns going to the pool has a leak when under pressure. Probably because when the guy came to clean my pool the first time it was after a lot of rain, and his plan was to drain the water to clean. Before he could get it drained completely, a bulge began to form in the shallow end from rain water under the pool. I believe this bulge caused a damaged pipe at a return jet above where the bulge is. (Probably not a good idea to drain the pool but there was a lot of rocks in the pool from when they backfilled)
So I have two problems. One is a possible damaged line that is leaking only when pressure is on the line. The pool level does not lower any that I can tell when the pump is not pushing water through the pool.
I don’t know why I don’t have the pressure I think I should for the spa jets. But now that the spa plumbing is separate from the pool plumbing except for the skimmer line that runs to the pump, I can only assume today that when my spa was drained down, it backed up in reverse after the pump was off and pushed water up through the skimmer. I assume this because the pool level is way higher with the spa drained. I do not believe he installed any type of check valve to stop the water from draining back into the pool. But since the plumbing is separate on the return line side, I know the water isn’t backing up through there. Can it back all the way back through the pump up through the skimmer?
Would a check valve increase the spa pressure? I am used to the water in the pump being all the way up to the clear lid but with this setup even on the quick clean mode it doesn’t get up there which makes me think there is a pressure issue.
