Need some real help guys...

Im at wits end with the 480c on my truck. Its leaking from god knows where. I know its coming from the comp cuz I can hear it. I just replaced the cylinder wall thinking that was the problem cuz its wore down pretty bad. Its still leaking like a bitch though. I need more ideas and some solutions besides buying a new one. I have NO money what so ever at the time. I am not able to drive my truck cuz it leaks down and i have to run the comp ALL THE TIME. The truck will literally leak all the way to the ground from full lift in about 10 min. Isnt there supposed to be a check valve on the leader hose? IDK WTF.

Its stressing me pretty bad and putting me in a hard spot. I have to pick my son up from the daycare every day starting next week and the only thing I have to drive is my truck. I doubt it will be covered under warranty and wont even try from the horror stories i have heard from others trying to get it done. Anyways, help is very appreciated.

Ya that's about the only complaint I can have with a viair is almost every one I have ever seen the check valve goes bad
But just get u a new one and put it inline between the tank and comp that should fix ya right up
Not sure if u have a grainger near u but I have bought a few from them for about 20 bucks and all is good again

or fix the other leaks....

so there are no other leaks in the system. the truck has all top dollar fittings and everything was installed correctly. I know whats leaking and its the compressor. There really is no guessing as far as that goes as I can hear the air leaking out at the compressor when I get under the truck. I think im gonna borrow some cash and pickup a check valve. Anyone else have the check valve problem?

well if ur looking for a quick fix just pull out the leader hose and put a quick connect fitting on it and just fill it at a tire shop or something that will at least work for now.

Im having a hard time finding what I need. You can forget SD or QAR. They have nothing in stock. Any suggestions for places selling check vavles with a decent price?

Your local Parker store (or pretty much anywhere that deals with hydraulics/hoses) will have check valves. They're around $25 I think though.

I have a 380 and have the same problem. This is my second hose and still the same problem. Im just gonna put a check valve inline with the hose. On mine the air is coming out the intake port when the comp is not running.

It does sound like the check valve would be the first thing to look at, but I have been running Viair compressors for at least 6 years now and have never had an issue with a check valve going bad. I can supply new leader hoses or SMC check valves if you are interested. Check out my site or shoot me an email to brian@illusivefabrications.com If you have your receipt from the compressors I would suggest contacting Viair if it is still under warranty (1 year) they are pretty good about getting things taken care of from what I have heard before.

BINGO. thats what mine is doing. I will be looking around town this week for an inline check valve. I get paid friday so hopefully saturday I can get one. I am driving the truck as of today. I am looking at it out in the parking lot. lol Its not too fun, I spend most of my time turning on and off the compressor.

Anyways, thanks alot guys. Saved me some anxiety and money.
