I watched Kevin Shorts video on backwashing spraybars and finally got around to do it today.I played around with it some and it appears one of the ball valves is for the recycle spraybars and the other ball valve for the aerator spraybars – correct?The recycle ball valve (starboard side) has a fair flow but the aerator ball valve (port side) just has a trickle.I also noticed my aerator spraybars dont flow very well…about half of the holes has flow…nothing like what was in Kevins video.So I figure the aerator spraybars are clogged. Another thing is when I turn the aerator on it takes about 5-10 seconds to start pumping but I figured it was just getting primed.What things should I check out? Could I take the screen off the inlet and jet water up it with the garden hose? Would that hurt the pump?Last edited by 1958 on January 12th, 2013, 11:49 pm, edited 1 time in total.
