I have an AG pool; a SuperFlo 2sp 1 hp pump; a Clean and Clear Cartridge filter; a MasterTemp 400 btu HD heater. My pool is an Intex that has a through-wall skimmer added; one return; and another suction port that was original to the Intex, and has a plunger valve on it. The pool is plumbed with 1.5 inch flexible hose, which sits on top of the ground because I take everything away in the Fall. The flex hose runs from the pool to the equipment pad with a few slight, very gradual curves along the way (around flowers and a sandbox). I have approximately 75 feet of this hose from the pool to the pump, and so another 5 feet or so from the heater to the pool on the return.
Issue 1 (I noticed this situation last year well as this year):
When I run the pump on low and have the plunger on the non-skimmer suction port open, there is not enough suction through the skimmer to pull debris into the basket. Even cottonwood things float by and when I open the skimmer lid there is stuff floating on the water over the basket. If I close the non-skimmer suction port I do get an acceptable amount of skimming action. Does this seem abnormal?
Issue 2 (I noticed this last year as well as this year):
When I put the pump on high, I get sub-par vacuum performance with the second suction port open. I have to close it to get a really good vacuum job done. Does this seem abnormal?
Thanks for any input as to whether this performance seems normal for my configuration.
