    Question about blowing out the lines

    Going to try to close my pool by myself for the first time.

    A couple questions about blowing out my lines (I have two skimmers, 3 returns, and one main drain in the deep end)

    My impression from reading some posts and watching some videos is that I can plug my blower (I plan on using the Cyclone vacuum and blower - 3 HP) directly into one of the skimmer return and then, assuming I can control the airflow using valves and plugs I can blow out all the lines from that one connection.

    First, does this sound feasible?

    Should I be bypassing the filter when I do this (I have a cartridge filter)? If not, should I take the cartridges out before I do this? If I should bypass the filter and for some reason I cant - will I need to change plans and blow the lines out from the equipment pad?

    In-ground (24x40) vinyl pool (~30k gallons), Pentair Clean and Clear Plus cartridge filter (Model CC420P - 150 gpm), Pentair 1.5 HP pump, Pentair MasterTemp 250 Heater. TF100 test Kit.

    No need to bypass the filter unless it's easy to do so, but I would remove the carts first. You can indeed blow out the entire pool from one skimmer hole with a cyclone blower. Be sure not to forget to blow out the heater by opening the drain valve(s) during the process.
