I have an Intex 24' x 52" ultra frame. I lowered the water below the filter holes and removed the plastic parts. I added the winterizing chems, put in a pillow and covered it with a winter cover. It has rained and now water is coming out of the filter holes. I have tried to find something to cover the holes, but have had no luck. This is my first year leaving a pool up for the winter and would like any help. Thx.
