    Default Re: Upgrade recommendations for replacing 14" Intex sand filter combo?

    Thanks! I looked at that and some Pentair equipment. It seemed like Pentair was more costly. Is it really that much better? Would this https://www.amazon.com/Hayward-SP175...Cp_36%3A-25000 coupled with a 16" or 18" filter be better than the 1hp 18" complete system? A few dollars extra for a better system is ok for me. The max flow on the .5 hp pump is 55 gpm, which is far above the max flow of even the 18" filter. How many gallons the .5 hp will push through a 16" or 18" filter? Would the .5 hp pump provide enough flow to properly backwash? Would I still need a throttle? Would it hurt anything to plump the 18" Hayward to my Intex pump? Seems to me the worst case would be it wouldn't flow enough to do the job.
