I have a Rheem 86V in the up flow configuration.
I had some sewage backup in my basement and it looks like some of it went up my condensate line into the HVAC because there was no air gap. I noticed a few cupfuls of water on my air filter and at the bottom-front of the machine and when I opened the panel I saw about a quarter inch of water on the floor of each compartment.
I'm assuming the overflow come up from the condensate trap directly into the inducer blower chamber through the drain hose, and then it dripped down on top of the blower. How can I find out how far up the storm/sewage backflow went up into the machine?
I opened some of the yellow caps in the inducer motor and a cupful of water came out of it so it looks like it made it up into the inducer motor chamber and collector box.
