You may need to cap an outdoor faucet as part of winterizing a building or to prevent unsupervised children from using the faucet. The process is fairly straightforward but varies slightly depending on whether you are capping the faucet to prepare it for winter or as a safety measure.
Things You'll Need
- 1" threaded cap
- Wet/dry vacuum
- Channel-lock pliers

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.
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.
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.
