1. where do you place check valves?

I have 2 SMC one way check valves. im running 2 AZ compressors, and 2 smc water traps

A. Between tank and water trap?
B. Between compressor and water trap?
C. Valve (vu4) and tank?

 

in my particular phantom air cup kit. the phantom stock check valve (that was leaking air back into the compressor apparently) connected between the tank and the IN steal braded hose line (that leaves the compressor and goes into the tank). i just replaced the new SMC check valve with the stock one and problem solved...


NOTE!!!

in my case the SMC check valve was 1/4 female connections on both ends. my stock phantom check valve was female in and male out so i had to get a small piece of 1/4 pipe with male ends on each end to screw in between the tank and the new smc check valve.

 

same here with sojah, (B) at the end of steal braded hose line before the water trap.

 

So ... Compressor ->> braided hose ->> check valve ->> water trap ->> tank. Is what yall are saying? Lol just wanna double check so i can pick up fittings today

 

That's how my setup is........

 

When looking at complete air suspension kits, does it replace your stock suspension? I've seen some people sleeve their coilovers with bags and its kind of confusing.

 

Any pics of how it looks in the car?

 

here a picture in the car

 

1. yes it replaces your stock suspension
2. the ones you are describing is a bag coilovers set up Using UAS sleeve bags, cup kits also look similar to this. if you have anymore question feel free to ask. The simpler the kit along with direct replacement is the best way to go, but it does cost more than the sleeve bags and coilovers setups

 

swtjlsy, why do you need 2 tanks?

 

more stand by air and they are 2 3 Fallon tanks I think now I could have done only one and would have been ok

 

The bigger total tank capacity, the less often compressors will turn on.

 

Thanks for posting a pic swtjlsy its give a good idea..

 

If you are running AZ compressors you wouldn't need any check valves because the one that come with those compressors are pretty well made. However if you still want to add them for peace of mind it's best to do it between water trap and tank. I also would add one between the tank and the valve because it'll stop any back flow if you have a leak in the tank.

 

The order should always be.

Compressor > Braided hose > Check Valve > Air Tank > Water trap > VU4/Solenoids Valves > Air bags

The there is no reason to have a water trap between the compressor and tank. The water traps are supposed to protect moisture going to the VU4 manifold.

Here's a installation diagram from Accuair. I'll post up a photo of my setup when I got time later today.
