How to Attach a Tub Spout

A worn tub spout can lead to a variety of problems including leaks and weak shower pressure. Replacing a tub spout is inexpensive and easy, and doesn't require any special tools or plumbing experience. Tub spouts are available in a wide variety to match many decors; however, almost all tub spouts attach using one of two simple methods.

Slip-on Tub Spout

• 1

  Remove any caulk around the existing tub spout. Use a putty knife and work carefully to avoid gouging or scratching the surface of the tub or wall. Determine if the tub spout is a slip-on type by looking for a small Allen screw on the bottom of the spout.

• 2

  Remove the Allen screw by turning it counterclockwise with an appropriately sized Allen wrench, and pull the spout off the supply pipe.

• 3

  Slide the new tub spout onto the supply line and tighten the Allen screw.

• 4

  Caulk around the base of the spout and smooth the caulk with a damp finger. Clean up any excess caulk and allow the caulk to cure according to the manufacturer's directions. Turn on the water and check the spout for leaks.

• 5

  Repair any leaks by loosening the Allen screw, pressing the tub spout firmly onto the supply pipe, and retightening the screw while maintaining pressure on the spout.

Screw-on Tub Spout

• 1

  Use a putty knife to remove any caulk around the existing tub spout. Work carefully to avoid gouging or scratching the surface of the tub or wall.

• 2

  Remove the tub spout by turning it counterclockwise until it comes off the supply pipe. Clean the threads of the supply pipe with a wire brush to remove any PTFE tape, pipe dope or corrosion.

• 3

  Wrap the PTFE tape clockwise over the threads of the supply pipe until all threads are covered in two layers of tape. Alternatively, you can lightly coat all threads with pipe dope.

• 4

  Slide the new tub spout over the supply pipe and turn it clockwise to screw it onto the threads of the supply pipe. Tighten the tub spout until it is hand-tight and the opening is facing down.

• 5

  Caulk around the base of the tub spout and smooth the caulk with a damp finger. Clean up any excess caulk and allow the caulk to cure according to the manufacturer's directions. Turn on the water and check the spout for leaks.

• 6

  Repair any leaks by firmly screwing the tub spout onto the supply pipe.
