Compressor check valve
Is there a check valve on main compressor air line that goes to main compressor TRU 750 could this be a check valve, I would think there would be a check valve on compressor so it’s does not always pressure on compressor ?

There is a check valve on the outlet side of the dryer, pt# R950017, that protects the air tanks.
Here a link to a post I made a couple of yrs ago here on PC about the Wabco Super Saver Dryer. It has some good info and links.

The dryers does not look to expensive so maybe I will up date it to the Wabco Saver 1200 ? The system air fill inside of PS rear side door fills air system it tees in to dryer at the same port as the main fill to compressor, If there is a check valve on the out port of the dryer when you open valve that fills system should there not be pressure there? Mine does! When I 1st got coach almost 2 years ago I took it in to a Detroit dealer about 60 miles from us and had valves adjusted, and they said dryer needed work so they said they put in a rebuild kit. I don’t know much about dryers,Iknow what they do but the workings of them NOT. I’m going to put the bus up on the ramps now I got all the brake Piggybacks and Diaphragm’s all replaced and now Tag will lift off the ground now, So I’m going too replace relays and pull dryer off and check it out. Looking at dryers it shows on the Wabco Saver 1000 and 1200 there is some kind of pressure regulating check valve on the primary or secondary tanks and I don’t have one of those?? Is this the right chose to replace dryer and is the Wabco Saver 1200 the correct replacement for this??
