I'm new to the pool game. Just recently bought this house in October which came with a salt system pool. I have had to replace the pump, Pentair variable speed, and replaced the multiport valve this past Tuesday. I have had an issue with dirt being in the pool and thought it was due to my neighbor constantly cutting his dirt!!! picking up leaves haha. I vacuumed this morning and there is already dirt back in the bottom of the pool. i thought the valve would fix this...................any suggestions? as far as I know, I think I am vacuuming right!!!!!
