Ok TFP folks. Thanks for all your chemical wisdom and teaching me how to keep my pool a sparkling oasis. Now I have a much different problem.
Woke up today to an empty pool.
I posted last night in the rain rain go away thread about having to drain water daily due to all of our rain. "Someone" went out to drain again last night and did so on waste setting. Turned pump off but left filter handle on waste. This morning pool is drained to maybe 1foot of water in shallow end.
1. did this happen because the knob was left on waste or am I looking for some other malfunction?
2. I don't know what to do once full as I'm sure there is air in all plumbing now.
Filling as I type but that will take a while I guess.
