New member here and I will soon be replacing my equipment once I get my water adjusted properly using the methods on this site (Thank you very much for this awesome site). I'm curious if I should get the 6 position valve instead of the push pull even though I only need to be able to backwash (which I can't even do now)? Are the 6 positions more reliable or last longer? I have an 18k gallon pool, no spa or water feature, very basic. Also I am going to buy Hayward. Thanks, and sorry if I left out any needed info.
