I'm a new pool owner and have read through as much as I can on the site, very helpful.
my system is was built around 94, using 1 1/2 piping. 2 skimmers and main drain are very far from the pump (80-100 ft each for return lines, about 30-50 each for supply jets x 3 plus small jet by stairs)
28,500 gallons, 27" sand filter, 1.1 hp pump and Polaris booster.
my filter and Polaris pump need replacing
am am I correct that I am limited to about a 45 gpm flow because of the piping? I know bigger is better to some degree with the filter, but at that flow rate it looks like a 24" filter is still enough, even a 22 could work?
im confused on total head given the lengths vs the charts I'm seeing for pumps. Could I get rid of my booster if I put a two stage pump in?
thanks for the help
