I got a deal on a new Hayward Perflex EC75A de filter. According to Hayward this filter should be matched to a pump with a 30-100 GPM output. However, my 2 hp pump delivers 110 GPM. What are some options to "dial back" the pump pressure to less than 100 GPM? Would installing a check valve between the pump and filter help?
Thanks in advance for any suggestions.
