Changing the seal of the head of a faucet.
Over time, faucets tend to drip. Generally, this problem comes from a deterioration of the valve rubber ensuring the closure of the valve. The remedy in this case is simple: just change this seal.
Tools and materials needed
Fats for faucets.
a wrench or flat keys.
a set of flat screwdrivers
Step 1: Preparations
Before starting the operation, turn off the water supply and check that there is no more pressure by opening the tap on which you are about to change the gasket. Then check that all your tools are at hand and that the drain of your sink / sink is closed to prevent the screws from falling into the water drain.
Step 2: Disassembly of the head
Start by unclipping the colored plastic pellets noting their position. You will clear the access to the screw that allows to fix the plastic part of the head.
Engage a suitable screwdriver in the hole thus cleared, unscrew and disengage the plastic part of the head.
The brass body will disassemble then with a flat key or failing, a wrench.

Step 3: Disassembly of the parts head
To disassemble the parts of the faucet head, remove the brass "U" which blocks the axis of the groove where it is located. Then remove the axle from its support, and disassemble the other parts.
Step 4: Change the seals if necessary and lubricate the parts
Clean the rooms, and scrape areas where limescale deposits have formed. Then check the various seals (the O-rings and the flat seal of the valve), and change them if they show signs of wear. Below from left to right, the new seal and the old one.
Next, grease the pieces where they will be playing: around o-rings, washers and threads.
Step 5: Reassembly of the parts head
To reassemble the parts of the head, proceed as for disassembly. Check, that the pieces play on each other without forcing. Then place the head in the closed position: this will prevent deterioration of the seal during reassembly.
Step 6: Repositioning the head and tests
Reassemble the faucet head and tighten without forcing using the wrench or wrench. Then open the general water supply and test your faucet.
Step 7: Replacing the plastic part of the head
If step six went well, you can reassemble the plastic elements and switch to the other faucet if necessary.
