I called Marissa and verified the axiom feeder was just low on water. The under slab heating system was turned on over the weekend as it was cold outside. While the system is running it will remove air from the system depleting the reserve of water in the axiom hydronic tank. The tank needs to be filled up. Marissa filled it up while I was on the phone and the axiom feeder started pumping again. I’ve instructed her to monitor the system and let us know if there are any leaks or if the axiom feeder keeps having to fill up which can indicate a leak in the under slab loops themselves.
