I "thought" that a .5 hp pump coupled to a 14" filter was ordered. Turns out that the pump is .75 hp. and still a 14" filter that takes somewhere between 50 and 100 lbs of sand. My first inclination is to throttle the intake to slow the flow through the filter sand and lower overall pressure. Would it be better to throttle the exhaust and increase pressure? I'm not happy with either option, I think it will make the pump work harder either way. I do think I'm less likely to break something if I restrict the intake. Am I worried about nothing important?
