I went to close my pool on my own for the first time last weekend and it went pretty well except for a couple of issues. I was screwing in my plugs into the return inlets and two of the three jets still had air bubbles coming out leading me to believe water would still seep back in once the air pressure was removed. I wrapped the plugs with teflon and I'm not sure if I did it but the two that were leaking were leaking around a the cracked cover plate.
Would replacing the cover plates solve the problem because I don't see there being a big seal behind the cover? I really need to get the pool closed this weekend because it's dropping below freezing. I might just have to lower the water past the two plugs but I hear that's really bad on pool covers. Thanks in advance!
