Remove the plunger, spring, and seat, and check the rubber seat for dirt.

Clean the valve body (7) and the rubber seat if necessary by flushing them with clean water. Let water run both ways through the body to flush any dirt from the valve.

Carefully place the seat, spring, and plunger back into the valve body. Be sure the large diameter of the spring is pointed up.

Place the stem over the plunger and lightly press the stem seal into place.

Replace the coil and press it firmly against the body.
