HWH Jacks won't go down
I just tried to lower my jacks, and I can hear the pump run, but the jacks don't move. Where to begin? Slide still works. Tom 2001 Winnebago Adventurer

Best I can gather, the shuttle valve is a mechanical valve that sits on top of the main HWH body. It is a valve that has a 3-inch hose connected to it. I'm not sure what it does, but it may be the issue. An earlier post says it only works for retracting, but it's in the troubleshooting guide as a potential source of the problem if they won't extend. I'll keep everyone posted as I learn more.

The Shuttle valve is mechanical ONLY. 3000 PSI will overcome any defect in a shuttle valve. Shuttle valve failures involve Low pressure retraction issues. I have NEVER seen a shuttle valve fail when 3000 psi applied. Possible, but I have never seen it happen. The fact that you manually opened the T handle and a jack started to extend means the Shuttle valve was operating. LOSS of your power/fuse blowing would not be a shuttle valve. DO NOT remove the shuttle valve to attempt to test or look at it. The O-rings will be destroyed. ONLY remove a shuttle valve if you have a new replacement on hand to reinstall. The shuttle valve is the gateway for all fluid going to and back from the Jacks only, not for the slide system. Doug
