Cusser Posted February 17, 2019 Report Share Posted February 17, 2019 I have a 1988 CalSpa and I routed the water path out of the cabinet to an external cartridge filter (and back) which makes stuff so much easier !!! The factory filter housing was difficult to remove the top housing due to clearance issues, and the giant plastic nut kept breaking (over $20) and I continually had leaks at the O-ring. So that has worked for me. I added shut off valves on both sides of that new filter. I have never thought about moving the pump externally; I did need to replace a "wet end" seal on it over a decade ago. On my CalSpa, the water path is pump-heater-pressure switch-filter.
