A new valve and / or a new seal. An adjustable wrench or pliers. A screwdriver. And if necessary, a sharp and sharp knife.
The mixers are often made a strong contribution, so it is not uncommon that with time leaks appear at the bottom of its handles. These leaks are mostly due to the degradation and aging of the valves that regulate and cut off the flow of water when you open the faucets.
Step 1: Remove the faucet handle.
- Turn off the water before starting your intervention. To do this, close the shut-off valve that controls the power supply of the mixer in question or, failing that, the main shut-off valve located immediately after your water meter and which feeds the entire network of your installation. Then run the water to empty the pipes completely.
- Then using the sharp edge of your screwdriver or the tip of a knife, remove the colored pellet, which covers the screw holding the spigot of the tap. The brace is the other name given to the faucet handle. For smooth faucet models without color pellet simply unscrew the top of the spider.
- Remove the faucet handle completely by loosening the retaining screw or pulling on the crank, if it is not held by a screw. Then you see the head of the tap.
Step 2: Remove the faucet head and proceed with the repair.
- Using an adjustable wrench or pliers, unscrew the clamping nut that holds the valve head in place to remove it from its seat.
- With the valve head removed, you can now see the offending valve (indicated by an A in the picture below). According to the mixer models, it can be fixed by simple casing or retained by a screw and can be, as here, extended by a plastic cap.
- Remove the valve and replace it. Make sure that the seal of the central part (B) is in good condition. If this is not the case, or if you are in doubt, change it.
Step 3: Clean and reassemble.
- Take advantage of the mixer taps being removed to clean the lime deposits that have accumulated on the faucet head and in the cavity of the seat on which it usually sits. Then reassemble everything, not forgetting to replace the cap or plastic trainer on the head of the tap, or the colored pellet on the spider.
- Then restore the circulation of the water in the circuits and try to make sure that there are no more leaks.
- If ever your problem persists, it may be the seat of the faucet head that is damaged. You then have two solutions in front of you, either perform a repair using a bead (see our sheet readjust the seat of a valve head), or you decide to change your mixer and why not, replace it with a mixing valve (Replace a mixer with a mixing valve).
