How To Clear Debris From a Pool Spring Flapper Check Valve

Step 1

TYPES OF SPRING FLAPPER CHECK VALVES - This picture shows the two popular styles of Spring Flapper Check Valve. Both provide access to the flapper mechanism from the top of the valve. One is screwed down with 8 screws. The other is secured with a more convenient twist on Cover Nut. Although this guide is written with references to the Cover Nut version, it is also applicable for the 8-screw version.

Step 2

REMOVE COVER NUT - Twist the Cover Nut counter-clockwise and lift it off the top of the Check Valve.

Step 3

LIFT OFF COVER/FLAPPER - Lift the cover off the top of the Check Valve. You may have to pry it a little to get it started. The Flapper is attached to the bottom side of the cover and will come out with the cover.

Step 4

CLEAR DEBRIS - Clear any debris away from the inside of the valve and around the Flapper and its spring.

Step 5

LUBRICATE O-RING - Turn the Valve Cover over and inspect the O-ring. Replace the O-ring if broken or stretched. Lubricate the O-ring with a small amount of silicon-based lubricant. Do not use oil based lubricant like vaseline.

Step 6

REPLACE COVER/FLAPPER - Fold the Flapper down and replace it and the cover into the top of the valve. Make sure the flow arrow is going in the correct direction. Make sure the O-ring is set properly and that the slots on the cover line up with the tabs on the valve body.

Step 7

HOLD COVER - Hold the cover on the valve. There may be a tendency for the Flapper to spring the cover off.

Step 8

REPLACE COVER NUT - While holding the cover in place, screw the Cover Nut onto the top of the valve clockwise.
