Hi All,
I could use some advice on next steps for my pool losing water.
I was intending to close the pool yesterday for the winter. I had the pump running for the last 2 days. On Saturday, I cleaned it thoroughly, but didn't get time to blow out the lines and put the cover on. On Sunday, I woke up to a half-empty pool. The pool was running overnight that night. I heard it sucking air from the skimmers when I woke up.
Currently, I have this situation:
I called the only local leak detection company that I know of, and they said they won't work on outdoor pools again until about April.
Right now, I think it could be any one of the following, but please let me know if I'm missing something here:
For now, I'll wait to see if the water is continuing to fall and see where it stops. Once (or if) it stops, then what is next? One local pool guy suggested I plug all the piping and re-fill the pool now, but that still means that it could be a pipe or the multi-port valve.
If I decide that next Spring is the time to replace the liner (it is at least 15 years old as far as I know and could be 20-25 years if never before replaced), do I need to have the pool filled up to a certain level over the Winter to hold everything in place?
Thanks!

I heard it sucking air from the skimmers when I woke up.
Currently, I have this situation:
- Water is well below skimmers and return jets
- Water is at the top of the lights
- Pool has one main drain
- It is an inground pool with vinyl liner
- Pool was losing water very quickly with the pump on
- I marked the water height this morning. Not yet sure if it is steady or just going down slowly with the pump off.
- Pool is 36K gallons. Can't find where 15-20K gallons disappeared to.
I called the only local leak detection company that I know of, and they said they won't work on outdoor pools again until about April.
Right now, I think it could be any one of the following, but please let me know if I'm missing something here:
- Main drain - leak at the drain or drain pipe. Two local pool experts I called said that this is very, very rare, so they are saying this is low likelihood.
- Return lines - Pump could have been sucking water from the main drain, then on returning to the pool, the water is lost through a break in one of the return lines.
- Lights - there are 2 lights, but I doubt this is the cause since the water drop was fast with the pump on and slow/negligible with the pump off
- Liner - for same reason as the lights, this doesn't seem likely
- Multi-port valve - Maybe something broke inside this. I did not see any evidence that the backwash hose dumped tons of water though. Usually the grass and leaves in the yard show obvious signs of being blasted with water. It was raining pretty hard, so maybe the rain hid the usual backwash visible signs. I wish I would have tested the valve before putting the filter away yesterday. Is there a way to debug without hooking everything back up again?
For now, I'll wait to see if the water is continuing to fall and see where it stops. Once (or if) it stops, then what is next? One local pool guy suggested I plug all the piping and re-fill the pool now, but that still means that it could be a pipe or the multi-port valve.
