my pool is 23 years old and still using the original equipment. 23000 gal 1.5 hp Jacuzzi pump 150 sq ft cartridge filter.
I would like to replace the filter and the pump. I am thinking a 425 sq ft Hayward cartridge filter pn# c 4030 and a Hayward variable speed pump model # sp 2302 vsp. The pool plumbing is 2 inch pvc. the current clean filter pressure is 16 psi. I put a vacuum gauge on the pump and it read 8. I calculated the TDHP at about 46.
Any suggestions would be greatly appreciated.
