T&S Brass Pre-Rinse Spray Valve Replacement Instructions

Picture - T&S Brass Pre-Rinse Spray Valve Replacement Instructions

T&S Brass’ pre-rinse spray valves are known for their precision and efficiency. Although they’re built to last, you may eventually have to replace your existing valve. If you need to install a new one, this set of T&S Brass pre-rinse spray valve replacement instructions details the process clearly and concisely so you can maintain your faucet with ease. 

This guide is for B-0107 and B-0108 pre-rinse faucet spray valves.


Preparing the Faucet

  • Step 1. Turn off the water - Use the faucet handles to turn off the water. However, unlike when installing the faucet, you don’t have to cut the water supply or drain the lines.
  • Step 2. Check for water - Press the spray valve handle to see if any water comes out; if it does, let it drain out completely before proceeding.
  • Step 3. If necessary, remove the valve handle (B-0108 only) - If replacing a B-0108 valve, use a screwdriver to remove the handle before proceeding.

Uninstalling the Old Valve

  • Step 1. Loosen the spray valve - Use an adjustable wrench to hold the ring above the valve. Then, begin turning the valve counterclockwise in order to loosen the connection.
  • Step 2. Remove the valve - Uninstall the defective valve by twisting it in a counterclockwise motion. 
  • Step 3. Pull out the washer - Reach into the hose outlet and take out the old washer.

Installing the New Valve

  • Step 1. Install the new washer - Place the new washer into the hose outlet.
  • Step 2. Attach the replacement spray valve - Insert the new spray valve into the hose outlet.
  • Step 3. Screw on the spray valve - Tighten the connection by holding the hose ring with an adjustable wrench and twisting the valve clockwise.

Replacing the Spray Face (If Necessary)

  • Step 1. Remove the existing spray face - Use a Phillips screwdriver to uninstall the existing spray face. Once it’s loose, remove the spray face and rubber bumper.
  • Step 2. Install the new spray face - Insert the new spray face and rubber bumper into the valve.
  • Step 3. Tighten the connection - Make a secure connection by tightening the screw; however, don’t overtighten the screw as doing so can cause the spray face to crack.

Resuming Normal Operation

  • Step 1. Check for leak points - Turn on the water, press the handle and check for leaks in the spray valve, such as around the spray face and at the hose connection point
  • Step 2. Evaluate water flow - Press the handle and examine the flow from the spray valve to make sure it’s consistent. If it isn’t, the new spray valve may be defective and should be replaced.
  • Step 3. Flush out the system - Push down on the handle for about one minute so that water can flow through the spray valve and flush out any debris created during the installation process.
  • Step 4. Use the unit normally - Resume normal operation of the faucet and spray valve.
