Q: How long does it take for a purge valve to empty?

A: After the system purges, there is a slow but steady air leak from the purge valve. Shut the truck off and it still leaks. It will loose down to 60 psi in about 45 minutes, and is completly depleted in about 1.5 hours.

Q: Where is the check valve on a Meritor dryer?

A: There are three lines to the dryer, the largest from the compressor to the dryer, the next from the dryer to the wet tank, them a small line from the dryer to I think the governor.This small line looks to be 3/8″.Which one will have the check valve. The Meritor parts list shows a check valve in the dryer on the outlet port.

Q: How long does an air dryer kit last?

A: The kit is about the same as a new dryer (least for mine) And the rebuilt ones last about 6 months. You’ll usually run into a plumbing nightmare when switching air dryers. I was going to upgrade to a bendix but would’ve had to change a lot of plumbing and said screw it the 300 junk wabco is fine.
