What does a manual override actually do on RV leveling jacks?
A manual override is a hand-operated backup system that lets you extend or retract your leveling jacks without power. When your HWH or Lippert Level-Up control board dies, the hydraulic motor won't turn, and you're stuck at whatever angle the coach is sitting. The override uses a mechanical hand pump or crank that connects directly to the hydraulic manifold, letting you operate each jack independently.
It's not elegant - you're pumping by hand - but it works. We install these on HWH RapidCamp and Lippert Level-Up E systems almost weekly.
The override doesn't replace your power system; it's insurance. Most jobs run $320 to $420 in parts and labor.
A Winnebago Brave owner in Tampa called us last month after his control board fried during a thunderstorm. His coach was nose-down, unhitched.
He couldn't level, couldn't move the jacks, couldn't tow safely. We installed a manual override pump in 2 hours while he waited.
Cost him $380. Two weeks later his new Lippert Level-Up control board arrived and we swapped it in.
The override stayed on as a permanent backup - smart move. He can hand-pump if the power system ever fails again instead of paying for roadside assistance.
What the override system includes:
- Hand pump or crank mechanism
- Hydraulic hose connections to manifold
- Ball valves for jack isolation
- Mounting bracket on coach exterior
- Operation manual and safety labels
- Quick-disconnect coupler (some models)
How do we diagnose if your leveling system needs a manual override installed?
You need a manual override if your power leveling jacks won't respond at all - no movement, no grinding, dead silent when you press the button. This points to either a dead control board, burned-out jack motor, or severed hydraulic line. First we test the power: battery voltage at the control panel, continuity through the motor connectors, pressure at the pump outlet.
If power is there but no hydraulic pressure builds, the motor is seized or the pump is dead. If there's no power signal at all, the control board is toast.
Once we confirm the main system is down and repair is days or weeks away, the override becomes practical. We've diagnosed this on Jayco pinnacle models, Grand Design Reflection fifth-wheels, and Forest River Sunseeker Class Cs.
A Tiffin Motorhome owner in Boise had his Lippert Level-Up jacks stick halfway up. His control board wouldn't cycle, and the dealer had a 10-day lead time on replacement boards.
He called us on day two. We ran voltage tests, confirmed the board was dead, and quoted him $890 for a new board plus installation.
He asked about a manual override as a stopgap. We installed one the same day for $340.
He hand-leveled for a week, then we swapped in the new board. He kept the override on - he'd seen the failure happen once and didn't want to be stuck again.
Symptoms that mean manual override is a good idea:
- Control board completely unresponsive
- Jacks stuck mid-extension or retracted
- No power reaching hydraulic motor
- Repair parts on 5+ day backorder
- Coach is unsafe at current level angle
- You're boondocking far from service
Walk us through the manual override installation process step by step.
Installation starts with locating the hydraulic manifold and pump - usually mounted under the coach or inside a basement compartment - and clamping off the main pressure line. We drain any residual hydraulic fluid into a catch pan, then thread the new hand pump inlet into the manifold. For HWH systems we typically use a manual pump kit that bolts to the exterior wall near the main electrical compartment.
For Lippert Level-Up rigs we install a lever-handle pump or crank pump directly into the manifold cavity. Each jack gets its own isolation ball valve so you can level one corner at a time. We run new hose from the pump to each valve, pressure-test at 100 PSI to check for leaks, then label everything - this is critical because misusing an override can blow a seal.
A Keystone Cougar fifth-wheel came in last week with a dead HWH pump motor. The owner was staying at a state park and couldn't move.
We jacked the coach level with bottle jacks, clamped the main hydraulic line, and bolted a new manual pump assembly to the exterior wall - took 90 minutes. We pressure-tested it to 150 PSI, bled the air, and had him practice pumping one jack up and down.
He was nervous - hand-pumping 10,000 pounds of jacks feels sketchy at first - but after two minutes he had it. We left detailed labels on each valve: FRONT LEFT, REAR RIGHT, and a warning not to overpump.
Installation steps in order:
- Locate manifold and pump under coach
- Clamp and bleed main pressure line
- Install hand pump or crank assembly
- Thread pump inlet to manifold opening
- Install ball valve isolators on each jack line
- Run new hose and pressure-test at 150 PSI
- Bleed trapped air from system
- Test each jack independently
- Label all controls and valves clearly
- Provide written operation instructions
What does a manual override install actually cost, and what parts are involved?
Manual override kits run $180 to $280 in parts; labor is $100 to $170; total job is $280 to $450 depending on your jack system and how accessible the manifold is. HWH systems usually run cheaper because the manifold sits in an accessible basement cavity. Lippert Level-Up installs sometimes cost more if we have to move storage bins or run hose through tight spaces.
You're buying a manual pump (HWH hand pump kits are around $140, Lippert Level-Up manual manifolds run $160 to $220), stainless steel hose, ball valves rated for 3000 PSI, fittings, and a mounting bracket. We always use Parker or Gates hydraulic hose - not the cheap stuff. You might also need new hydraulic fluid if the system got contaminated, another $30 to $50.
We quoted a Grand Design Momentum fifth-wheel owner $340 last month for a full manual override install - his Lippert Level-Up control board had failed and he needed to level while waiting for parts. The breakdown was $220 for the manual manifold kit, $85 in hose and fittings, $35 for fluid, and $0 labor (he watched and learned).
When his new board arrived two weeks later we removed the override in 30 minutes. He asked us to leave it installed as a permanent backup. We charged him $75 for that, which is just the labor to verify it still held pressure and re-test all four jacks.
Parts included in a typical override kit:
- Hand-pump or lever-crank assembly
- Stainless steel braided hose (25 to 50 feet)
- Ball valve isolators (4 to 6 units)
- JIC or NPT hose fittings (stainless)
- Pressure test gauge with adapter
- Mounting bracket (aluminum or steel)
- Hydraulic fluid (2 to 4 quarts, if needed)
- Instruction labels and warning decals
How long does a manual override install take, and can we do it while you wait?
A manual override install takes 1.5 to 2.5 hours from start to finish, and yes - we do these while you wait in our covered metros. It's a mobile service; we show up with the pump kit, tools, hose, and fittings already loaded. The actual work is straightforward: locate the manifold, clamp and bleed the line, install the pump, run hose, pressure-test, bleed air, and label controls.
The longest part is usually just getting access - moving storage bins, removing trim panels, or routing hose around other equipment. If the manifold is easy to reach, we're done in 90 minutes.
If it's under three layers of luggage racks and slide-out equipment, closer to three hours. We respond 2 to 4 hours from your call in our core coverage areas, so the whole job from first phone call to you pumping jacks by hand is usually same day.
A Coachmen Class C owner in Ocala called at 8 AM saying his jacks were frozen. We arrived at 10:15.
His pump was seized, total death. We drained the system by 10:45, had the new manual pump installed and pressure-tested by 12:20.
He was leveling by hand by lunch. The whole call-to-done was under four hours, and he paid $320.
He stayed in that spot for three days while waiting for a replacement pump to arrive from the distributor. Our override kept him level and stable the entire time.

What warranty and support do you give on a manual override install?
Manual override installations carry our standard 90-day workmanship warranty - if the pump leaks, a valve fails, or hose pops off due to our install, we fix it free. The warranty doesn't cover wear on the hand pump itself (that's user-dependent) or if you over-pressurize and blow a seal. What we do guarantee is that the system is properly pressure-tested, hose is routed safely, connections are tight, and all four jacks can be operated independently without cross-bleeding.
Most overrides run trouble-free because they're simple - no electronics, no motors, just hydraulic fluid and mechanical valves. If your coach is still in our service area and something fails during those 90 days, we come back and fix it. If you've moved out of state, we'll walk you through it by phone and can authorize a local shop to do the work under our warranty.
We installed a manual override on a Winnebago Adventurer in Jacksonville two months ago. Pump worked perfect for eight weeks.
Then the owner over-tightened the hand pump handle, cracked the internal seal, and fluid started weeping out. That's user abuse - not our install - so it fell outside warranty.
But we quoted him $85 for a new pump assembly and swapped it in the next day because he was good people and the original install was solid. He paid the $85 without grumbling. That's how we operate: warranty means we stand behind the work, not that we fix everything forever.
What the 90-day warranty covers:
- Hose leaks from bad crimping or routing
- Loose or weeping fittings from install
- Valve failure due to defective parts
- Air trapped in lines causing operation issues
- Pump bracket failure or loosening
- Labeling errors or missing instructions
- Does NOT cover user over-pressurization
- Does NOT cover neglected fluid maintenance
