I am sure I am not the only one to ever think how nice it would be to not have to unroll / Re-roll that backwash hose and hard plumb a setup to the discharge location... That being said, I have read that the backwash line should have no 90 degree angles in it.. That kind of quashes my plan.. My sand filter is inside an unfinished pool house and I need to turn the flow out the back wall, essentially 90 degrees at some point.. Is it that important to not have 90's? Will it cause too much back pressure at the filter? I have a 60-80GPM pump into a filter made for 50GPM.. Already a less than ideal setup.. Or is it more dependent on the distance the 90 gets placed away from the filter? Is it possible to do what I want to do? The pool house has the ability to occupy a straight run of 5-6' before a turn would "have" to be made... Or can I put the 90 towards the ground and then another 90 out the back wall? Would the gravity offset the back pressure I am assuming would occur??
Hope this is as clear as my water! Thx.
