Is my air dump working?

[lawjohnson]

I have a 98 Holiday Rambler Endeavor 35' DP.
I have a center neutral rocker switch on the dash marked dump.
I have pushed the switch both ways, (I'm thinking one way for the rear, the other for the front) but I do not notice the coach dropping or hear any air escaping while sitting in the coach.
Is there an easy way to check to see if it is working?

Thanks

On my 2001 Endeavor 34’ you have to put in neutral the transmission and turn on the leveling jack. Then push the air dump valve. On mine you have to hold down until you see around 60 psi on air tanks to know bags are empty.

I forgot to mention the engine has to turned off and the key turned to ACC.
I can hear the air release in from the dump valve on the firewall by the generator. If you can have someone in the rear drivers side they should be able to hear that valve releasing.

Thanks Ray... I will give it a try!
