How to Connect a Faucet


    – Step 1: Connect the faucet to the water supply

    – Case 1: Connection with a U.S. gasket fitting or a glued fitting

    – Case 2: Connection with nut

    – Step 2: Connect the faucet to the bunghole.

    – Step 3: Check the installation

With flexible screw-on connections, connecting a valve is a quick and easy procedure. Besides, the material needed to join a valve is readily available on the market.

If your installation’s supply pipes are not equipped with a connection system, you will have to place a two-way (also called instantaneous) coupling at their end. This fitting should be selected to match the copper supply pipe’s diameter on one side and the screw-in hose on the other.

Materials for connecting a tap

    – Double cone fitting

    – Wrench

    – Silicone grease

1. Connect the faucet to the water supply

To install the biconical fittings on the copper supply pipe and the hose, you have the choice between :

    – a connection with a so-called American joint fitting (also known as a grip fitting) ;

    – a connection with a nut.

Note: the cold water pipes on the right and the hot water pipes are on the left.

Case 1: Connection with a U.S. gasket, or “grip” fitting

The American gasket fitting offers an optimal seal and is removable. It is equipped with a toothed metal ring that will hold the nut’s seal and the bicone fitting.

    – Grease the ring of the nut with silicone grease.

    – Thread the nut, the ring (with its teeth pointing towards the end of the tube), and the seal onto the feed tube.

    – Then, install the fitting on the end of the line.

    – Tighten the nut on the two-cone fitting to crush the ring and ensure a tight seal on the fitting.

    – Do the same thing on the hose side to ensure the connection with the supply tube.

Important: Observe the assembly sequence described above. Also, ensure the metal washer’s teeth are pointing towards the end of the tube because these teeth will seal the assembly.

Case 2: Connection with nut

A brass ring will guarantee the tightness between the nut and the bicone fitting.

To connect the hoses to the water inlet pipes:

    – Thread the nut onto the supply pipe.

    – Then, thread the fitting onto the end of the tube.

    – Tighten the nut: the brass should press against the fitting to ensure a tight seal.

    – Do the same on the hose side to make a connection with the supply tube.

2. Connect the tap to the bung.

Once you have made the valve connections, you must connect the valve to the bung through a control rod.

    – Inside the valve body, insert the bung control stem and screw the lower stem in place.

    – Then, insert the lower end of the stem into the ball joint.

    – Adjust the size of the bung valve. The plug should be able to close entirely and open sufficiently.

    – Tighten the screw.

3. Check the installation

It is strongly advised to check that you have correctly connected your faucet.

    – Run the water, boiling water.

    – Run the palm of your hand over the pipes and fittings to check for moisture or leaks.

    – Check that the water drains typically through the bunghole.

    – If there is a leak, disassemble the fittings and repeat the process.

To improve the faucet connections’ tightness, you can use silicone grease to coat the screw threads.

Now you know how to connect a faucet. Hopefully, this will help you.
