HWH Question

When I park and set up with my HWH 625 system it works just fine. The problem is after about 24 hrs it will loose it stability. I need to push the jacks down button in the front and rear for just a second and will stabilize again for about 24 hrs. What or which valve is leaking and how hard is it to replace or repair?
Thanks in advance
Don

it either has dirt in the seat or the oring seal will need to be replaced. any one with mechanical ability can replace it but it will be a bit messy

Make sure your reserve fluid tank is filled to the lines on the bell vent shaft with all jacks re-tracked.
Should be leveling by rails, where yellow light is lite that pair on pass or drivers rail front and back lifted together by rail.
To lift jacks two front or two rear may flex coach and pop out windshield.
A leak can come from the top of jack where your jacks sensor down alarm is located may just need to be tightened or new "O" ring or is getting by "O" ring inside jack cyclinder and jack may need replacement.
New jack from HWH about $325, if your handy you can replace.

From your comment that you have to tweek both front and back it sounds like all jacks may be settling. Have you considered if the jack pads are simply sinking into soft ground ? Boards under jack pads or locating on harder surface may be all thats required. Just saying as you don't state what surface is under the jacks. When we drop onto dirt/grass surfaces the same thing happens.

To answer some of the questions...
We have no leaks I can see, we were parked on a concrete surface and I have to tweak the jacks every day or every other day. It just takes a tap of the button to stable the coach again.
Thanks
