Title: Loss of Air Pressure
Post by: jeffprupis on May 09, 2017, 10:44:34 PM
After sitting for 24-48 ours our air pressure reads zero (0) on both red and green needles.  Currently at Henderson LineUp in OR. They have identified the following part as leaking under soap test. They can't ID part. Can anyone help? On my way the BCS and would like to have them order and install is possible. TIA

Those are the HWH valves for air leveling often called the six pack.  One in the front and one in the rear.

Would these valves leaking cause air pressure to drop as read on the dash Air Pressure Gauge? The coach levels fine and adjusts periodically. HOWEVER, over a period of 24-48 hours the gauge (and air pressure) drops to Zero. The coach also airs up fine and holds pressure (120-130lbs) while driving. TIA
