Rain! Pool full - drain or wait?

[Phillbo]

I'm more concerned with water getting behind the pool walls at the coping than chemistry when mine gets flooded .. If the water is at or above the top of the tile, I backwash until it is in the center where I keep it.

Mine is right at the top line of the tile after about 5-6" of rain in the last week. DH and I were debating a drain - if we get another soaker today - I am draining about 2" out.

Yes you will need to add more salt if you have to drain and your salt level is low - my pool builder says that the warning light is just that - a warning. But if you drain it the salt concentration will not increase - just add about 1/2 as much as you think you will need and then test and see if you need more.

We are on a well so we are thankful for a good rain to fill our pool. We drain/backwash so that the skimmer works and let evaporation take over from there. If we have a big rain expected, such as tropical storm, we drain some water prior so we won't have have the problem of water behing liner. I am interested to know if we could retrofit an overflow valve to our existing pool...that would certainlly be helpful if we were out of town and couldn't manage the water.
