Had a FMM failure notice today at work. Had my brother check the ATO top off reservoir. It was low and the pmup must have sucked air. When I came home and topped off the tank, I found the pmup was running without pumping. I pulled it apart and the wiped off the rotor. This is a new pump (Less than 30 days old). Powered off the FMM, pulled the aquabus and repowered it. PMUP Back together and it's running. Has anyone had this issue?
(I plan on having a flow monitor in the ATO / PMUP line in the future to see if there is flow.)
