14’ round pool 1.25”inlet line I connected 1.5” line to increase flow as I have a Raypak 18kw heater after the filter but it requires flow rate greater than 15 gallons per minute. With this setup I am only getting 13 gpm. How do I increase my flow rate? I have an intel 635T filter pump that supposedly gives 19 bpm flow rate.
New filter installed. There are no adjustments to the heater other than adjusting your set temp. Both pump and heater are brand new. Bad flow sensor maybe?
