Blowing lines/antifreeze

[Bethdemarco]

See attached photo. Lines have been blown, filter’s removed, pump off. Gizmo in skimmer with some antifreeze.

Where do I put the antifreeze for the actual lines. Says through pump out flow. It keeps coming back out, not going down.

Help

Returns get the antifreeze before you put the winter plug in assuming you dropped the water level below them. You can use a funnel with an attached clear vinyl hose and get the hose to follow the path of the 90° and then push it a little further down the line then pour the antifreeze about half gallon per return and be ready to get the plug on quickly as sometimes the line has no pitch so the antifreeze tries to run out.
Couple up the SWCG but leave it somewhat loose in case some water finds it's way from the lines. Remove the handle on the valve that airlocked the main drain so it can't get tampered with.
