Lippert hydraulic leveling system

[Zonkpdie]

I’m losing pressure on the front jacks, with no visible leaks either on the jack(s) themself or by the pump. Any suggestions why?

Are the jacks drifting down or is this while the jacks are down?

An internal leak in any jack can cause that. The pressure will leak across the seal from one hose to the other.

Do you regularly apply silicone spray to the jack pistons to keep them clean and the seals lubricated? If not, I'd give that a try first. Run the jacks down until they just touch the ground, apply the spray, and run the jacks up and down a few times.

There will be solenoids in the hydraulic system, probably on the pump manifold, that close to hold pressure. It's a very common problem for these solenoids to start leaking slowly and not maintain pressure.
