When my pump is on high, my pressure is usually around 20, and when it gets above 25 or around 28, I backwash. Ive never ran the pump on the slow speed, for I thought it would take forever to turn the water over twice, and of course when the people who installed my pool said to run it on high....Yes my equipment looks very similar to the picture, for my set up came in a bundle package. Im assuming crown pool stores, where I bought my pool, uses waterway products, and it comes with the pool package...Ill get the exact measurements from my pump and motor tonight, then post for you guys...With that being said, the guy I called out to service my pump did say my pump is bad, and said I was luck enough to get 4-5yrs out of my filter...Basically saying its junk,,lol….He said he would help me upgrade to a DE filter if I want, with a 1hp pump, or if I want to stay with the same equip, he would help and install new one....Now im wondering what is a good affordable and durable system for a 16 x24 ABG pool....
