Re: So embarrassed....
I've often wondered about the drain/refill vs. SLAM approach. I barely noticed the cost of the 9,200 gallons of water required to fill my pool when it was new, and I don't believe I have an issue with a shallow water table. In any event, it only took about 10 hours to fill my pool. Could the pool shell pop up in such a short time?
While I don't see it happening, if I ever really let it go and ended up with a swamp, I'd be inclined to drain/refill--especially with a cartridge filter. If it just turned a little green or cloudy, I'd SLAM it. My only concern is the water table issue.
I suppose the water table can change, but there clearly was not a problem when my pool was built.
