Manual leveling of the HWH system

Manual leveling of the HWH system, I am not sure if I am doing something wrong or the HWH system needs to be checked. When I do auto level and after the system finishes, if one side or the other needed rising I use the manual button to raise that side. The problem is when I go to store the jacks, when I push the store button the RV drops down to where it was with auto level. It doesn’t ease down, it drops like a rock. I would appreciate any suggestions on how to correct this.

I had my system recalibrated in Red Bay.
They told me this Auto-Level procedure
1. Auto Level with slides IN
2. After completing, EXTEND all slides.
3. After completing, Press Auto-Level again
just to compensate for weight shift

All three of the coaches I've had with hydraulic levelers drop pretty fast. The higher up the coach is to level the more severe the drop. It shouldn't just drop to where it was auto leveled, it should drop onto the axle stops and the jacks should retract all the way. After that it should air up the suspension.

That is what I have done with the two coaches I have owned. Never had a problem.

Thanks Ted for your post and all the others who posted, this is a great idea the next time I set up I am going to try it.

you need a set of velocity valves. these valves, installed in the manifold, replace the regular hose connection fittings, and will eliminate that drastic dropped feeling.
just detach the hoses, and replace the standard fittings.
one at a time, so the hoses don't get crossed.
the jacks are self bleeding, so just run them down and up a couple of times and you are good to go.

these valves do not restrict the flow when extending. only when retracting.
when a hwh system is stored, the front jacks retract first. then, after five seconds, or so, the rear start retracting.
that original drop is surprising, and upsetting to some, including my wife. these parts will eliminate that complaint. part number is RAP90280
if you need help, contact me at 1-602-549-3638 or pfmaddox@att.net

Paul thanks for your post and the offer of help, I will show your recommendation to the folks who replaced the HWH jacks. At my age I don't do any work on the RV that requires crawling under the RV
