How to Add an Outdoor Faucet
- 1). Drill a 1½-inch hole in the foundation if the faucet is going there. Push the faucet supply end through the hole and use masonry screws and a drill to secure the faucet to the foundation.
- 2). Connect the supply pipe to the supply end of the faucet and secure it to the faucet with a clamp.
- 3). Run the other end of the supply pipe over to the outlet side of an emergency shutoff valve and secure it with a clamp. Connect a second piece of supply pipe to the inlet side of the emergency shutoff valve. Secure the pipe with a clamp and run the other end of the supply pipe over to an existing water pipe.
- 4). Shut off the water supply and relieve the existing water pressure by turning on some of the faucets in the house.
- 5). Cut the existing water pipe with a pipe cutter and insert a T-fitting. A T-fitting is shaped like a T. This allows the addition of a side branch that comes off the main branch. Connect the new faucet to the side branch of the T-fitting.
- 6). Connect one of the remaining sides of the T-fitting to the water pipe that runs between the well (or main water supply) and the T-fitting. Connect the other side to the pipe to the line that runs between the T-fitting and the house. Add clamps to all three sides of the T-fitting.
- 7). Apply expanding foam sealant at the hole where the faucet comes out of the foundation wall.
- 8). Turn the water back on and check for leaks.
