Hello all. I had a similar post but today is the day for me to do this all. Wife and I have our first pool and next season we are going to replace the vinyl liner and I may also replace the DE filter as well. Let the pool go about 3 weeks ago and its totally green with lot of debris in it and I live in the Northeast getting buried with rain right now. I am need to drain some out for sure and I am thinking of draining it below the skimmers. If I use the multi valve port waste cycle that will bypass the grids I assume. What would you do? Clean as much debris as I can from the pool just run the waste cycle for a while. Then what do they do at closing that I may have to have done anyway aka so the pipes dont freeze here in the northeast etc? I assume I just cant cover the thing up and wait right?
