Pool remodeled. Changed from old stair step overflow from spa to pool to a full on cascade. 2 inch pipe, runs are from 35 to 75 feet. Pentair biggest DE filter, Polaris  360, had to carefully valve to get decent cascade. After freeze up here in Texas, some plumbing repairs, still need to update one valve which I have on order here at Inyo,  have same 2hp challenger pump. Pressure is low like below 10 lbs when I open pool jets, would going to a 3hp pump help?
