Air valve to actuate the dump leaking - Land Yacht - 06-07-2017

on my passenger side dump, there is a air valve that actuates the dump valve when you move the electrical toggle switch which is leaking. Tomorrow I will go buy the fittings to cap it off, then maybe I can remove it to see what it is, but was hoping somebody might already know from the picture below.

The air line comes into the unit in the middle of 2 brass fittings that look like air bleed off valves. The lower one is leaking. Anyone familiar with this unit?

i have did these several times. if you do a search i describe my efforts with it.

they use these for the dump valves on both sides and my bay fridge/freezer slide.

what fails on them is the inner rubber plunger. i have taken many of them apart and all of them failed in the same way.

a new valve is 100-150 bucks. i think you can find the rebuild kits for 30 or so if i remember right.

Thanks Tom, I found the rebuild kit on eBay, it went up $5 since your post :-)

So the o-rings in the kit will fix the brass exhaust valve from leaking? The picture of the kit did not have the brass exhaust valves.

Hi Mike - I need to try the rebuild Tom suggests. I guess between the two of them ( one on each side of my coach ) they have been a PITA. My present solution, which is easy and inexpensive, was to install a needle valve in the incoming air line to the solenoid pair. When I need to change the position of the dump valve I open the needle valve, hit the switch and then close the valve. No more leaks!

I had to rebuild mine also. I understand the function of the device is to cushion the the paddle when opening or closing the sewer valve.

The brass exhaust valves were added by Newell. Adjusting them controls the opening and closing speed.

I did like Russ but also added a switch at that compartment so I could operate the dump without going inside or having the ignition switch on.
