How Does Hydraulic Leveling Jacks Work?

Well, the purpose of leveling jacks is to make sure that your RV is evenly standing. The process is a lot easier if you have an auto-leveling system installed in your RV.

However, hydraulic jacks are run by using hydraulic pressure or liquid pressure. The hydraulic jack has a tube. And the tube is filled with liquid.

So, the jacks have springs on them. The liquid in the tube creates hydraulic pressure. This pressure pushes the springs on the jacks to make them extend. And reduce the pressure to bring them back up. That’s basically how the hydraulic jacks work.

Now, let’s look at some of the types of hydraulic leveling jacks available. Although all of them serve the same purpose, there are quite a few variations.

RV Hydraulic Leveling Jacks Leaking: How to fix it

When the hydraulic jacks start leaking, the jacks won’t work properly. This could ruin a long-awaited trip that otherwise could have been great. So, what do you do to save the trip?

Here are the steps to guide you through the fixing process.

Locate the leak

Before you can fix the leak, you have to locate exactly where the leak is. This might seem a bit difficult. But there are two common areas that tend to leak more than others. First, try and search in these common areas. They are

  • Hoses
  • Tubes

Try to watch each of the jacks to find if there are any leaks in them. If you find it then go to the next step.

Clean Up The Mess

The leaking fluid tends to make a mess around the place. If the place is messy, you can’t fix the leak properly. So, begin by cleaning up the leaking fluid.

Furthermore, If the temperature is too low, you can pour warm water on the base to make sure any more leaks aren’t frozen up.

Then to the next step.

Make the repair

Depending on which part has the leak, you’ll need to take different steps. We have broken it down part by part for your convenience.


The hoses carry the liquid from the tube to the jacks. The liquid then creates water pressure. If the hoses are leaked, then the proper water pressure won’t build up. Which means your jacks won’t extend properly.

You can’t really repair a hose once it has a hole or a leak in it. Temporarily repairing it will cause the same problem again. You’ll have to measure the hose and get a new one of the same size.

The good thing is, the hoses that are provided with the RVs are not that great quality-wise. If you go to a hardware store, you’ll find better quality hoses. Getting a better hose makes your leveling system more durable.


The tubes hold the liquid for creating the water pressure. If the tube is leaking, the liquid level will keep dropping. This will decrease the water pressure and the jacks won’t work properly.

The leaks in the tubes are mostly in the joints that connect the hoses with the tube. If that is the case, you’ll need to change the O-ring. O-rings are the rubbers components that are inside the nuts. When they are ruined, the liquid starts to leak.

Changing the O-ring will tighten up the nuts in the joints and stop the water from leaking.

If you’ve come this far and still can’t solve the problem then its time for the next step.

Ask for Help

If you’ve done all the steps and still can’t find the problem, it’s time to call for help. This could be as simple as asking around the neighbourhood and finding someone more experienced with the hydraulic jacks who can help.

There’s no shame in asking for help. You may even need to call a professional if things get too technical.
