I have a 12,000 gallon in-ground pool with a spill-over spa. The pump that is currently installed is a 3/4 hp Sta-Rite. The filter is a cartridge type. I also have a heatpump in the system. When I have the heat pump in-line, I cannot get the jets in the spa to suck air down their vents to produce bubbles. The only way I can get the jets to produce bubbles is to by-pass the heat pump and open all the return drains from the pool to the pump but that cools off the spa. I eventually would like to install solar panels on my 2 story house. I have a feeling the pump is undersized, but shall I go 1hp or 1.5hp? Will I need to get a bigger filter for the larger pump? Pressure into the filter is 10psi with the heater bypasses and 19 with the pump in-line.
