HWH Jack problem

Right front jack keeps slowly retracting....like 1 inch after 7-10 days. Happened multiple times. Recently we went away for 6 weeks and when we returned this jack and the left rear jack were both no longer touching the ground. (Left rear just raised due to right front of rig lowering.)

I don't see any obvious fluid leak by the solenoids, nor on the jack foot pad nor on the ground. Any ideas what could be causing this?

That happened to us when the fluid was slightly low, but not low enough to set off our alarm. Filled (don't overfill) and cycles jacks up and down a couple time with a final fill and no more problem.

Read sometime/somewhere that these jacks need to be deployed at least an inch or so to keep pressure. Perhaps Doug can comment on this but I have been in the habit of making sure when I use the jacks that I "use" them instead of just touching the ground.
