How to Cap an Outdoor Faucet
- 1). Shut off the water supply to the faucet if you are capping it for winter. Skip this step if you are capping the faucet as a safety measure.
- 2). For winterizing, insert the hose of a wet/dry vacuum, such as a Shop Vac, into the end of the faucet. Vacuum any excess water out of the faucet. Let the vacuum run for a few minutes to get the water out of the pipes attached to the faucet. Skip this step if you are capping the faucet for safety reasons.
- 3). Screw a 1" stainless steel cap over the end of the faucet. Most standard faucets will require this size cap. Be careful not to cross-thread the cap onto the faucet. Tighten the cap with a pair of channel-lock pliers.
