Before you start

Tools you’ll need

Two 7/16-inch wrenches, two 9/16-inch wrenches, a 3/4-inch deep socket or box wrench, Vise-Grips, a marker, and a utility knife.

  5. Reassemble and test

    Return the lower adjusting nut to its mark. Reinstall the pivot connector, upper adjusting nut, draw straps, handle, and handle bolt. Restore the water supply and cycle the handle a few times. Check for leaks around the packing nut. If it still leaks, repeat the procedure and add another one-third piece.

Packing tip

Leave the old packing in place. Add only one-third of the new packing at a time.
