Based on a wide variety of things I think I need to empty out a substantial amount of water from my (13,000 gallons) gunnite diamondbrite finish inground pool. Living in Florida I've never had to do this (only drain a little rainwater from time to time) and I just want to make sure I'm not going to hurt anything.
If I connect the hose to the skimmer and put it into the pool (to keep the pump from running dry or at least getting lots of air after the pool goes below skimmer level) is there anything else I need to be aware of? I don't intend to leave the pool low for long -- going to immediately add water as soon as I get it down about halfway -- but I also don't want to make a mistake here.
The ground is pretty wet (we've had lots of rain the last few weeks) if that makes any difference (naturally the pool is surrounded by a concrete lanai). We have a very porous ground surface here in Florida -- water goes through it live a sieve.
Or am I worrying about nothing?
