SLOW AIR LEAK ON NIMBUS

Good evening
We have 2009 Nimbus.
I have slow air leak from the 4 air release valves that are mounted in front of left front tire. It seems like at least 2 are slowly letting air out.
In 24 hours dash gauge readings on both front and back go from 125 to low enough for red light to come on.
They look like individual release valves rather than a single bank of them. The turn knobs are loose and cannot / will not close 100%.
Does anyone have a part number or place to get these? We are about 100 miles from Nac but don't want to take coach there for a possible simple fix of replacing these.
Any help us usual is appreciated.

Craig,

A lot of coaches came with these:
PTP 103385 C-1 Drain Cock, 1/4" NPT

Your coach seems diffrent as you seem to have a valve that has a round knob attached to a valve stem. Look these over and see if you have room to install this type.  These can be got off the Net from lots of truck supply companies.  If this won't work and you have a truck shop in your area go to there parts counter with one of your old valves and they most likely can match it up or will have some type of replacement.

Here is a link to the 1st one that came up on the net. hunt around though PTP 103385 C-1 Drain Cock, 1/4" NPT: AnythingTruck.com, Truck & Trailer...

Before pulling these valves apart, spray generously with WD40. Lots of dirt can collect on the outside of the value and keep it from fully closing due to the dirt near the handle. This is an often occurrence on our 2007 Nimbus.
