The mixing faucet has a spout and a unique control for adjusting the water flow rate and temperature.

Installing a mixing faucet involves attaching it to the sink or washbasin and then connecting it to the water supply system.

Important:

  • Turn off the water to avoid leaks, using the stopcock if you have one, otherwise turn off the water at the house water supply.
  • Open a faucet to relieve the pressure in your pipes, then close it again when the water stops flowing.
  • Plug your sink.

Your sink or lavatory must be pre-punched to install a mixing faucet. If this is not the case, check on this post: How to Drill a Sink.

What equipment should I choose to install a mixing faucet?

You can choose between several models of mixing faucet:

Mixer faucet with anti-scald ring: The hot water’s opening is limited by a ring, thus preventing burns.

– Mixer faucet with notching: the notching blocks the opening of the mixing faucet handle in the middle of the tap, thus limiting the water flow. However, the maximum flow rate can be reached by pulling the handle harder.

Mix faucet with the sensor: the sensor allows you to automatically open and close the water without touching the faucet by placing your hands under the faucet spout.

– Cascade faucet: with a flattened spout, it cascades the water. A little cumbersome, it can also be thermostatic.

– The thermostatic mixer allows you to choose the water temperature and make it constant, regardless of the water flow rate. It is mainly installed in the bathtub and shower because it is bulky.

1. Assemble the mixing faucet

– Combine the different parts that make up the mixing faucet. These other parts are :

◦ the tubes, or flexible connectors, for the water supply ;

◦ the threaded rod to hold the mixing valve.

– Take the tubes or flexible supply hoses and screw them onto the threads at the mixing valve base.

– Fix the threaded rod next to the hoses in the remaining thread. Fix it first manually and then with a suitable screwdriver. This will give stability to the mixing valve.

2. Install the mixing faucet

The joint between the mixing valve and its support is sealed by the O-ring (in the shape of a buoy). This gasket is usually supplied when you purchase your faucet.

Place the O-ring between the base of the faucet and the surface of the sink:

– Place the gasket between the sink and the faucet.

– Then, insert the faucet into the space provided.

3. Attach the mixing faucet

– Thread a gasket over the hoses and slide it until it contacts the underside of the faucet holder.

– Install the protective wedge to prevent damage to the sink.

– Place the bracket on the shim. Then manually insert the fastening nut into the shim and tighten moderately.

Ensure that the faucet is correctly positioned and then tighten all the components using a wrench.
