I've had my Apex up and running for almost 2 months . I have a 1/4" flow sensor on my ATO line and a 2" flow sensor on my return line. Both are connected to the same FMM.
When I started the system my ATO flow sensor was reading about 7 gph coming from my PMUP and pretty consistent the first month. For the last couple of weeks the readings are running around 350 gph. Conversely, my return line flow sensor was reading at around 750 gph and is now reading 175 gph.
I initially thought there was some sort of blockage, especially on the return flow sensor, but I disassembled the line from the sensor to the return pump and found nothing. I'm still feeling a good amount of pressure coming out and would think I could tell the difference between 750 and 175. Additionally, my return pump is reporting the same power consumption as it did from when I first hooked it up.
Any thoughts on why both flow sensors have changed expected values?
