My inground concrete pool has the in floor cleaning system from Paramount, which has a dome just above ground with one incoming chamber and 6 outgoing chambers, 1 for the side returns, and the other 5 for the 5 sets of pop ups on the floor of the pool.
Most sites/forums/videos do a good job of showing how to take a compressor and put it in my Pentair pump from the drain plug and blow out the lines, but with this extra piece of equipment, I need guidance on what to do 1st, 2nd, and 3rd, where its in between everything.
Initially, I plugged the incoming pipe into my pump from the skimmers, to blow out all the outgoing water lines with my compressor and blew out each of the 3 returns and I plugged them. I expected that with the rotating module inside the dome of the Paramount, it would then rotate around the pop ups, but it didn't seem to. Paramount suggests using a winterizing plug they make with a tire type valve in it and blowing the pop ups out right from there, but I don't have one of those. Tried a 5 hp shop vac, but the hose is too narrow, so it didn't create a seal and wasn't effective.
I removed the rotating module and perhaps that's the problem, because without that, the outgoing chambers aren't opening, so i'm going to reinstall that and see what happens. Any suggestions here on "how" to blow those chambers out and if I should have done those first would be appreciated.
2nd question is whether I should be blowing out skimmers, from the pump back to the skimmers or from the skimmers to the pump. I can block the outgoing flow by plugging my Nature2 sanitizer chamber if that will force air back to the skimmers, but I don't have any control for skimmers vs main drain, so i guess I have to hope that enough pressure will reach the skimmers.
3rd and last question is for the Boston, MA area, how far down to bring the water line. With all the snow from last winter melting, I'm surprised the pool didn't over flow. I just bought the house last winter, so I'm not aware of how far down the previous owner took the water, but when I opened the pool it was right in the middle of the 3 rows of ceramic tiles, at the perfect level, which was quite a surprise.
Thanks to all posters for reading and suggestions.
