installed as per diagram. Place the check valve as shown in the diagram on top of the
heavier replacement spring, and the spring on top of the pump plunger and push it
back into the pump body holding it in with a finger. Note the magnetic part of the
plunger is on the opposite end of the spring. Replace the lid with the gasket on by
lowering your finger on to the red O ring sleeve without the plunger falling out ( the
plunger is about 2” long so you have room to lower your finger out of the way). The
red O ring sleeve will fit inside the pump tube and the black O ring will fit over the
outside of the pump tube and will require twisting and pushing the lid straight back
in. This is a little tight but that is what makes the seal. Rotate the gasket and replace
the screws.
