Winterize in Southern California

Draining to just above the basket and then adding fill water will work, but it will be very slow. Assuming you're wanting to drain 1/2 the water, I would say 3 or so drains of 1/4 would work. Otherwise, I've seen reference to the "sheet method" (can't remember if it's CarlD or Poconos that has used it) where you put a sheet of plastic on top of the water and drain from under the sheet as you fill on the top--it's supposed to keep the chems in the top and bottoms from mixing.

Here's an old thread that talks about the sheet method--see ChemGeek's reply toward the bottom of the thread..http://www.poolforum.com/pf2/archive...hp/t-6121.html

I've done an in-place refill before without using a sheet. The key is to introduce water at one end of the pool without too much mixing (pump off) while at the same time, remove water at the other end of the pool, preferably the deep end via a siphon. I have replaced over half the water this way and the result seemed to work without too much mixing (i.e CH dropped as predicted).
