Hi, This was my first year closing my pool and we live in Canada where it will freeze. I followed all steps I could find from this forum, other websites, pool chemical supplier etc. I have only had a problem confirming that I've blown out all my lines successfully. Pretty sure I've blown out the return lines, as I saw water go to just blowing mist out of the jets. I drained my heater and pump, and blew throught them to be sure of the same. I blew through my filter, and saw mist coming out of the pressure valve and clear bottle openings, and just dribble coming out of the bottom drain cover opening. But it still feels quite heavy.
My biggest concern is the skimmer lines. Water would not blow right out of the lines. Seems to be at the new lowered pool level. I have only one line going back to the pump and equipment pad, so somehow my main drain and skimmer are connected. The Pool supplier told me that I would not be able to blow out, because of this config, and to just use the foam cords and antifreeze.
Does this sound right? Really concerned I'm going to have a burst line under my skimmer or in my filter. Thanks for any help.
