Now you can install the new O-Rings!

**NOTE: The 100883 spout O-ring kit includes two thin, plastic rings along with the rubber O-rings. These plastic rings, called Bearing Washers, generally will not need to be replaced. In the rare situation where you find one of these plastic rings to be damaged or out of place, you may want to replace these. For this, please follow the steps in the “Bearing Washer Replacement” section at the end of this document before installing the spout O-rings.

Installation of the Spout O-Rings

  1. Place a new rubber O-ring onto the brass valve body and push down until fully seated in the lowest groove in the valve body. Once seated in the groove, make sure this O-ring is not twisted.

  4. You may now reassemble the faucet by following the disassembly instructions starting at step 9 and working in reverse order.

**NOTE: After assembling the faucet, turn the faucet on and inspect the area under the handle to insure there is not any water seeping out. If water is seen leaking here, remove the handle and the collar and tighten the retaining nut another 1/8 of a turn.

Bearing Washer Replacement

Use the following instructions only if the plastic rings need to be replaced

  1. Be sure to follow the “Removal of the Spout O-Rings” section to have the faucet disassembled and ready to replace the bearing washers. The upper bearing washer was removed in step 7 of that section and will be installed when reassembling the faucet using that same section and following the steps in reverse. The steps below will explain how to remove and install the lower bearing washer.
