UnderSink Mixer Kit



  1. Locate the Hot and Cold water angle valves under your sink. Turn on the hot water to verify which valve begins to feel hot and mark it with an “H”.
  2. Turn off both valves, disconnect the flexible water lines at the valves, and install supplied 3/8 T’s. (Lay towel below valve for drips.)
  3. The 3/8” Compression T’s are shown installed in the above picture. ( If the T does not fit, then you have either a 7/16” or 1/2 inch outlet on your valve, and you must either change out the valve or buy new Tees with a 3/8″ center outlet to fit your Valve.
  4. Connect the 18 & 20″ hoses to the side outlets of the brass T’s, then install the Tee assemblies on the valves. Use 18″ hose on the short side, 20″ hose on the long side.
  5. Mount the Mixer Valve on the mounting bracket, use one silver lock ring. The screw  holes should be on the SAME side as the lock ring
  6. Mark which valve inlet is Hot before mounting the valve.  Loosely connect the two inlet hoses, hold the bracket to the wall, and mark the screw holes.  Drill 1/8″ holes. Mount the valve and bracket, and tighten hose connections. (Snug but do not over torque hose nuts, since they all have rubber washers.)
  7. Locate a spot next to your toilet, on the side of your vanity cabinet, to mount the  1/4 turn Shutoff valve.  (Be sure you can route the 30 inch stainless hose from the Mixing valve to the Shut-off Valve without interfering with any drawers or shelves.)
  8. Drill a ¾ or 7/8 inch hole.  Slide the trim ring, with one white nylon spacer inside it, onto the Vanity On/Off valve.  Insert the Valve stem into the hole, and secure it on the inside, with the second nylon spacer and white plastic lock ring. (brass lock ring optional) Secure with 2nd sliver lock ring.
  9. Attach the 30 inch hose to Vanity Valve inlet, and firmly tighten the hose nut, holding the Valve in position with hose bib facing down.  Then, attach the 30″ hose to the Mixer outlet, and tighten.
  10. Attach the Hydrawand bidet hose to the Wall Mount Valve hose bib.
  11. Turn the water supply valves on, and check for leaks.
  12. Turn on the sink HOT water faucet until hot, and then adjust the temperature of the mixing valve to your preferred temperature. If your sink is far from your heater, you may have to turn the sink HOT water for 10-20 seconds to clear the cold water out of the line before using the bidet.

Note: Thermostatic mixer outlets are straight ½” pipe thread, made for Stainless flex hoses with washers. Tapered F.I.P. fittings will only catch the first few threads and should not be used.
