Air pressure for the bags

My HWH compressor is not functioning. Has anyone plumbed in an auxiliary and what pressure do the bags take?

Your original HWH compressor may be fixable or rebuildable.  Have you done any trouble shooting?

Several members have installed new replacement air compressors in their coaches.  Some use 12 volt compressors- some use 110 volt compressors.  Search the Forum for pertinent threads.

Note:  Any air compressor used to air up coach system should include a water filter to dry the air.

Your air bags can "take" any pressure up to and including the normal max air system pressure for your coach - around 120-130 psi (same as engine compressor cut-out pressure).

The air pressure going to your front 6-pack manifold is controlled by the pressure regulator mounted under the front of your coach near the two air tanks.

Here's some threads that may be of interest:

Check out this thread  - Don replaced his HWH compressor with this ARB 12V unit - there is a more complete third of the replacement, but this has some pictures - your 2000 has a low capacity 12V version - I have contemplated this upgrade.

Inverter Replacement

For now, I have an HWH switch inside the coach where I can turn off and on the pump at my conveninece from inside the coach if (when) I develop a leak and the pump runs too much (and subsequently burns out).  I have had the occasion to use this capability recently until I got some leaks near the compressor leading to the bladder fixed.  I also carry a spare 12V pump and rebuild them myself as needed.  (I actually think I have a spare rebuilt pump and a core waiting for me to rebuild......)
