My new pool had poor chemistry (according to pentair) and the heater core failed. Chemistry is now corrected and monitored based on forum instructions and using pool math. Regardless pool builder agreed to install a bypass to limit water through the heater since it's not needed except in colder months or when running the spa.
Prior to bypassing the heater my pump was running at 30 GPM and my filter pressure was around 8 PSI. With the heater bypassed the filter pressure drops to 0 PSI which sort of makes sense as the only thing after the filter prior to returning to the pool is the SWG. I assume the gauge is not sensitive enough at lower pressures to show a reading so how do I know when the filter is dirty and need to be cleaned? Should I just switch to a time / use interval? Is there something else I am missing.
FYI...The heater is not bypassed in the picture below
