I would like to clean the basket on my sand filter. I made the mistake of taking the lid off once before, that was a wet mess lol. I have one of them rectangle covers to go over the skimmer opening on the inside of the pool, so that would stop water from that side. Is there a setting on my valve that would also keep the water from coming from the return side?
Just want to clean out the basket and put some petroleum jelly around the seal of the lid so it goes on a little easier.
