Valves Need CheckValves Or Not....

I should have been specific. The way I said probably wont work on a single port bag.

Ur right Nick, everyone does have their own opinion. You don't NEED check valve but they work. If you don't want bleed back and you want some insurance, check valves are the way to go. I'm happy I put mine on because I got an air leak a couple of months back and got home because I some in. It was odd driving with no tank pressure and was still off the ground. They go b4 the fill valve otherwise how would it be able to dump? And check valve work on all setups and are no better for bags or cylinders.

b/c if your setup is on a T and your fill valve is on the tank then from that is a tee, straight ahead of that will be a fitting, on the bottom leg of the T is the dump, if you stick it before the t between the fill valve and the tee, your valve still has back pressure from the tank, but you can still dump b/c there is nothing blocking the fitting and the dump, the check valve is before that.

Here's now I did mineit's more for safety than anything, works great!

Ok! Cool! I new it needed a check valve just wasnt sure where to put it before or after. Thanks!

dude, pay no attn to all the different opinions and plumb your air system just like a hydro system. a check valve before each line to the bag and i recomend one on tank before the compressor so the comp. doesnt have to sit and hold pressure all the time.
