OEM replacement valve for EQ Systems manual override hand pump assemblies. Restores manual override capability when the original valve is worn, leaking, or damaged.
The EQ Systems ES1720 is the OEM replacement valve for manual override hand pump assemblies used on EQ Systems hydraulic leveling systems. The hand pump valve is the internal component that controls hydraulic fluid flow when the hand pump is operated manually — allowing jacks or slide-outs to be extended or retracted without electrical power.
If the hand pump is no longer building pressure, feels loose or unresponsive, or is leaking fluid during manual operation, a failed valve is often the cause. Replacing the valve restores full manual override capability without replacing the entire hand pump assembly.
EQ Systems hydraulic leveling pumps equipped with a manual override feature include a hand pump that allows jacks and slide-outs to be operated without electrical power — useful when the battery is dead or the pump motor has failed. The hand pump valve is the internal check valve assembly that allows the hand pump to build pressure with each stroke. When this valve wears out or fails, the pump handle will not build pressure and manual override will not function. The ES1720 is the replacement valve for this component.
The ES1720 is a valve replacement only — it does not include the hand pump handle. If your hand pump handle is also missing or damaged, EQ Systems offers a separate replacement handle compatible with all EQ Systems hand pump valve types. Contact EQ Systems support to confirm the correct handle part number for your pump model.
Have your pump model number ready when contacting EQ Systems support. The model number tag is located on the pump motor or manifold.
