Troubleshooting
1. The key problem most people have operating the LiquiVac is that the gaskets not sealing properly to hold the
vacuum. You can check this by listening for air leaks. Unscrew cap-valve from tank and remove gasket. Reinsert
gasket into cap-valve and screw onto tank as tight as possible using only your hands. Remove pump from tank.
Make sure the large black gasket is seated properly against the tank rim. Screw pump back onto tank and hand
tighten. If a leak is detected, check gaskets for wear and misalignment. Lubricate with motor oil, replace gaskets
and tighten cap until snug.
2 Make sure dial on cap-valve is in closed position when pumping, and hose is fully inserted tightly
into cap-valve.
3 If you have tried the above and each pump stroke does not result in increased resistance, then the internal leather
seals in the pump may need lubrication. Just apply several drops of oil onto the pump rod (at the handle end),
draw on the handle a few times to distribute the oil. Let pump rest in vertical position, handle side up, for 12–24
hours to allow leather to soften. After this time period, draw on handle a few more times, then reattach to tank
making sure the large gasket is seated onto the tank rim. This may be necessary when the pump has been stored
for several months.
4 If you accidentally over filled your tank or if the oil happens to enter the pump, you can unscrew the pump from
the tank and let the oil flow into a container (knob side down and unscrewed). After the oil is drained pump the
handle a few times to get the remaining drops of oil out. Keep in mind a small amount of oil in the pump is good
for the unit and actually prolongs the life of the pump by adding lubricity.
5 If you use the LiquiVac to extract water, please take the pump assembly off after use and allow water to drain out,
then add oil onto the pump rod at the handle end. This is necessary because the seals in the pump are made of
leather.
