Air set up question please help

I changed from two tanks to one cause I run nitrogen now. I hooked up all the lines but the tank seems to not be feeling, I am also running with three compressors so it should fill even faster right? Any help would be appreciated.

whats not filling your tanks, the comps or the nitrogen. is your nitro bottle opened and set to the psi you want it at?

^^^^^ yea what he said!!! that would help to know!

The tanks are not filling up!

CHECK VALVES BACKWARDS?

you might have to describe your setup and problem in more detail,

what compressors? size of tank? check valves? how are they wired? grounded properly? getting power? running a pressure switch? gauge to read tanks pressure?

let us know..

ok i had two 5 gallons hooked up to 3 compressors not sure the size. 3/8 inch lines and no gauges. Then I hooked up a nitrogen tank. I got the air running now but it takes like 30 minutes to air up one 5 gallon tank.

You either have a hell of a leak, you check valve is not right, or you have some old ass 20% duty compressors or something. I'd just run your nitrogen

what size line are you running off the regulator?

i used a 1/4"npt 1/2" line and it would fill it instantly.mabey your regulator sucks, what kind is it? post pics.

No my compressors are not that old maybe they are not sure, my shit was bagged just two years ago and when it was first built it filled in 5 to 10 minutes. I will post some pics on here.
