Hi, I have a inground pool. 25,000 gal and this will be the 3rd year I am winterizing my pool myself. The first 2 years it went easy, no problems. This year I am running into an issue and it is very frustrating. I started going through my normal winterizing process. I started by hooking up the air compressor and air locked the main drains, no problems, then I blew out and sucked out the water at the skimmer, again no problems. I plugged the skimmer hole and brought the lines back up to 20-25psi to start to blow out the pool jets. Normally when I do this one jet starts blowing out air and I plug it and go down the line until all 4 jets are plugged.
This year no matter what I try I cannot get air to blow out the pool jets. Air blows out of the main drain and skimmer just fine but not the jets? Can anyone please let me know if they have run into this issue and if you have any suggestions.
I want to get the pool winterized and this is driving me nuts, thanks in advance Dan.
