I posted this in another thread but did not get a reply, so will try here, as the return line is still nagging at me. I made an attempt at closing my pool myself and would appreciate someone telling me if it was done correctly and help me with my question.
I removed the drain plugs from the heater, filter and pump.
I bought a 5hp shopvac that blows. I blew out the skimmer line from the pool side and it went quite easily. All the water blew into the pump/skimmer, but it dispensed quickly since the plugs were removed. Once I was blowing just air, i poured in half gal RV antifreeze and screwed in the gizmo (used teflon tape on the screw end). I then added about 6 more cups of antifreeze into the skimmer "well" and put the lid on it. I then went to the equipment pad at the pump and using a cone shaped attachment, managed to blow the main drain quite easily (lots of air bubbles)and quickly closed the pipe off, blocking in the air. I assumed I was also blowing out the return but after stewing over it and re-checking the equip pad, realize I did nothing to the return line.
My biggest problem is how do you blow out the return with my type of set-up? It goes through the heater and filter, but how do I get air into the line, let alone any antifreeze?
