I'm having a recurring problem.
My yard is dirt and gravel, and so my pool is always dirty from it blowing into the pool when the cover is off. The problem I'm having is that when I try to vacuum it just blows right back into the pool through the return.
I have a relatively new Hayward cartridge filter (about 1yo). I just cleaned all the cartridges so that it was ready to go for the season so I don't see dirty grids as being the reason for the dirty return.
What other causes could be creating this problem? I don't want to vacuum to waste because with the dirt yard, i would constantly be VTW and spend a fortune in water, not to mention if someone saw me constantly doing it I'd probably get a nasty letter from the drought folks.
Any tips greatly appreciated
