Hi! We are new pool owners and this will be our first full season. We don’t wanna pay $400+ to have a pool company re-open the pool for us. We have a cartridge filter and have done some research on how to remove antifreeze from the lines. We understand that we can use a shop vac to remove it from the skimmer line but our skimmer is plugged and still under water. We don’t have any other drain. We aren’t sure from where we can pull the antifreeze at the pump. Picture attached if anyone can provide advice. TIA!
