I am assuming you have a HWH auto level system. If so it dumps the air before it starts to level. Quick way to see is store the level and build pressure and then have someone outside and level the system. Air should be dump if not then the level system should not work.
I assume the OP, when he talks of draining tanks, is wanting to be sure there is no water in the tanks. If just want air out of system, just shut off engine and pump foot value.
OP, the auto drains on my old Pete had a wire, for a small heating element, but the drain seamed to be controlled by time or pressure. With them and a well serviced air dryer, there should be no water in tank. Every fall I would pump air down and pull plugs to see if I had any water.
Yes it dumps the air before it starts to level. I hadn’t thought of that. Those things I’m looking at must have something to do with that. So if they are some sort of electric air dump valves then I suppose I don’t ever have to worry about draining the water out as long as I use the automatic leveling system once in a while. Does that sound right?
