Automatic air tank drain valves

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?

No, that does not sound right to me. To be fair, I have zero experience with air systems on MHs so what I say could be called trumpism.
OTOH, for well over half a century I have drove, repaired rebuilt trucks.
For most of that time, part of drivers daily maintenance was drain any water collected out of tanks before it could cause issues. As long as there where owner-drivers, that worked great. But because failure to drain tank is unlikely to cause issue the first day, slip-seat operations, where you are unlikely to drive the same truck 2 days in a row, demanded something that worked without driver input. So auto drain valves, and then air dryers became normal.
The reason I say using leveling system, (or any other system) to drain the tank, (assuming you are draining to make sure system is dry) is because for water to get out of the tank it must go thru all the lines and valves on it's way out. Once it does that water is in everyplace you do not want water to be.

When I ask if you lost air pressure when you level I did not mean that is the way to dump the tanks. I have 4 dump valves for the bags that dumps them. I take it you did not get the manuals for this couch. If you do not mine I will send some link so you can download and print out some check list. tank test sytem

AND, what chassis. The air tank drains are part of your chassis, not coach.

Thanks.

It’s a Spartan chassis. I’ve seen guys mentioning K2 Spartan chassis but I don’t know if ours is that one.

Call Spartan on Monday with your VIN and they can tell you very easily what tank drains your chassis came with. That doesn't mean if manual valve that the coach maker remembered to pull a lanyard to an easy to reach location.

The coach is a 40’ 2000 Newmar London Aire.

Thanks Opnspaces for the info. I got my RV info into my signature and I finally understand how to insert pictures. Here is a pic of the gizmos that are on the bottom of my air tanks.

Known as a Spitter valve, found on most trucks and can be heard every few minutes, some are electric and some are pressure driven. Listen to them for the better part of my life as I put in 60# yrs over the road.

Heated automatic drain valve is what it looks like. What is the make/name on it?

So what’s it’s purpose? Is it just to let water out if the tank?
