How to change sink faucet or bidet faucet?

The constant use of the sink faucet or the bidet faucet causes great wear and tear which means that sooner or later you have to replace it with a new one. The accumulation of lime can also be another reason that encourages changing the faucet since it clogs the pipes and causes the water to come out with little pressure, in addition to the fact that the lime water causes dry skin and hair, nothing questions recommended for our well-being.


However, in many homes they do not wait for the faucet to be damaged but rather make the decision to change it for other reasons, which are not merely functional, such as renovating the aesthetics of the faucet (either for another style or because the old one has some scratches or small bumps that make it not look as decorative as when it was new) or even for economic and ecological reasons since there are models that allow very interesting water and energy savings that you will see reflected in your bills and with which you will contribute to protecting the environment.


It does not matter what type of toilet faucet you are going to modify; whether it is the sink or the bidet, the installation process is basically the same, only the smallest workspace in the bidet area changes.


Replacing the taps can be a good time to check the operation of the stopcocks on the hot and cold water circuits for the sink or bidet on the wall. Here is the list of faucet for the kitchen you might be interested in

Step 1:

Remove the old taps:

Close the square cut-off valves for each toilet, corresponding to hot and cold water; if they are not damaged and do not need to be replaced, you can close them with your fingers with a simple right turn.

Unscrew the hoses from each of the cutting keys. Do this with the help of a spanner or wrench at first and finally with your fingers. If the hoses of your old taps were not flexible but rigid, it is best to unscrew and remove them directly from underneath the toilets.


Some water is likely to come out. Put a rag underneath and clean quickly to work comfortably.

Using the socket wrench, unscrew the nut of the clamping screw that is used to fix the tap at the bottom of each toilet by turning it to the left. This screw is at least 5 cm long, so you will need to finish unscrewing it with your fingers.

Remove the clamping pieces, gaskets, horseshoe clamping coupling and nut. At the same time, with the other hand, hold the tap, which will already be loose, to prevent it from hitting the toilet.

Remove the old tap, pulling it out from the top of the sink. The normal thing is that the tap itself comes out together with its old seal, the clamping screw and the hoses. If there is difficulty, unscrew and remove one of the hoses from the bottom.

Save the fixtures from the old faucet if they are in good condition. They can always come in handy for an emergency repair.

Step 2:

Put the new faucet in the sink or bidet

Before going to work, you should bear in mind that to tighten the taps and that they are well attached to the surface of the toilets, you will have to work in somewhat uncomfortable positions. Try not to force your back when bending over. If necessary you can lie down, if space allows it.


2.1. Place the gasket in the groove on the bottom of the faucet. If the flexible hoses are not already mounted on the tap, screw the male part into the threads of the base. Tighten by turning clockwise with your hand and top off lightly with a spanner if the faucet design allows. Do not overtighten to avoid breakage.

2.2. Next, fix the set screw or threaded rod. Squeeze with your hands and finish with the help of a flat-blade screwdriver. The stem usually has a indentation at one end to allow it to be fixed securely to the base of the tap.


Clean the surface of the toilets well, since there can always be some accumulated dirt that prevents a perfect seal when some water splashes during use.

2.3. Put the hoses from the top of the sink. The union nuts with the water taps are likely to prevent the two hoses from entering at the same time. Enter one first and then the other.


2.4. On the bottom, put the rubber gasket and the clamping piece on the stem, both horseshoe-shaped and used to press the tap from the bottom of the sink. At the same time as holding the tap, insert the clamping nut with your fingers and finish with the socket wrench.

2.5. Screw each hose to its corresponding water intake: remember that hot water is usually the faucet on the left and cold water is the one on the right. Tighten with the spanner. If any hose is short, you can always lengthen it by screwing another smaller hose, 10 cm, for example. Open the stopcocks and check that there are no leaks.


If the faucet does not have a water saving device, add one. Unscrew the diffuser from the tap with a wrench and insert the saver, which will have the same thread pitch. Tighten with the wrench without abruptness so as not to damage the enamel.
