New house with old filter, so I was told by pool store that the spent canister might explode if I back wash wrong... What the correct way?
Turn system off
open slide valve to back wash
open spent canister red pvc valve
turn system on?
is there anything I do to canister bag or whatever is inside?
then re add a little DE in skimmer
Thanks for your help!
ps when I have to open filter and take grids off when I hose down, is it hard to re assemble ?
They are trying to sell the service, should I just have them do it? I cleaned cartridges before...
