How to Install Service Sink Faucets


Service sinks provide a practical alternative to using laundry sinks when mopping floors or cleaning accessory parts for vehicles. Unlike other faucets, service sink faucets have a bracing rod that allows hanging a bucket on the spout when filling it with water. If you had a service sink installed with shutoff valves and stub-outs for hot and cold water, you can save some costs by installing the faucet. Service sink faucets are available in a variety of finishes, and they come with the necessary installation parts. Installing the faucet requires basic carpentry and plumbing skills and everyday tools.

Things You'll Need

  • Stud finder
  • Measuring tape
  • One-by-four pine
  • Handsaw
  • Cordless drill with screw-tip attachment
  • 2-1/2-inch deck screws
  • Adjustable wrench
  • Vinyl plumber's tape

Setting Up

  • Position the faucet with the spout facing out and the upper end of the bracing rod pointing toward the wall. Align the ports for the hot and cold water on the back of the faucet with the stub-outs at the wall. Mark the wall where the mounting plate at the upper end of the bracing rod will attach, and set the faucet aside.

  • Locate the studs in the wall at each side of the mark for the mounting plate, using a stud finder. Measure between the marks and add 3 inches. Cut a piece of one-by-four pine this length with a handsaw.

  • Set up a cordless drill with a screw-tip attachment. Position the one-by-four horizontal and flat against the face of the wall so each end extends 1 1/2-inches beyond the corresponding stud mark. Raise it up or down so the mounting plate will attach on the face. Secure the one-by-four to the wall with a pair of 2-1/2-inch deck screws into each stud.

Faucet Installation

  • Turn off the water supply to the stub-outs for the faucet. If the plumber installed shutoff valves, turn these off. Alternatively, turn off the valve for the main water supply to the house, and open a spigot to release water pressure in the pipes.

  • Unscrew and remove the caps at each stub-out at the wall, using an adjustable wrench. Determine which of the provided connectors are needed to install the faucet. To do this, hold the faucet with the spout angled downward and the ports on the back just below the corresponding hot and cold stub-outs. If everything lines up, use the straight connectors. Alternatively, use the offset connectors.

  • Wrap three layers of vinyl plumber's tape clockwise onto the male threads of the connectors. Screw the male ends into the ports on the back of the faucet by hand. Wrap three layers of tape around the male threads on each stub-out. Hold the faucet in position, and rotate the nuts on the outer ends of each connector clockwise to thread them onto the stub-outs.

  • Hold the faucet spout with one hand, and tighten both ends of each connector with the wrench. Attach the bracing rod mounting plate to the one-by-four by driving one of the provided screws at each machined hole on the plate.

  • Turn on the shutoff valves for the service sink. Alternatively, turn on the main water valve, and wait until water runs out of the spigot, then turn off the spigot.

Tips & Warnings

  • Installation and parts varies somewhat with the manufacturer. Read the installation instructions, and become familiar with the procedures and parts before installing the faucet.
  • Before attaching the one-by-four to the wall, brush on two coats of exterior wood sealer, and allow it to dry.
  • As an alternative to a one-by-four, cut out a section of the drywall or plaster, and install a two-by-four block between the studs with deck screws. Patch and paint the wall before installing the faucet.
