How to Use the CheckMate

Written By Grant Yoder

Here’s how to use the CheckMate™ backflow testing and repair tool.

To remove the seat from an old Watts 009 series check using the CheckMate™:

  1. Place the flat end of the seat against the friction plate that comes with your CheckMate™.

  2. Cover the spring retainer with the CheckMate™ canister, pushing the seat against the spring retainer.

  3. Then with with equal and opposing force turn the friction plate in the “opening” direction. “Open” and “Close” are indicated with arrows on the CheckMate™ canister.

  4. The check seat will easily separate from the spring retainer.

To assemble a Watts 009 series check using the CheckMate™:

  1. Insert the spring retainer into the CheckMate™ canister, then add the spring, the disc, and the check seat.

  2. Press the CheckMate™ friction plate against the check seat.

  3. Holding the CheckMate™ canister and the friction plate in opposite hands, press the check seat into the spring retainer.

  4. With opposing force, turn the canister in the “closing” direction to line up the locking lugs.

  5. With a quick snap, the check is assembled!
