Your faucet is supposed to be turned off, and yet you hear a drop… Then another drop… Then another… This noise is not only unbearable but is also often heralding a water leak in your plumbing! Unfortunately, this is not uncommon, and it is necessary to take care of it as quickly as possible, at the risk of seeing your water bill go up considerably. belimo valves experts explain the steps to repair a leak in your faucet!
Remove The Head From Your Faucet
You have to change your tap. Start by shutting off the water supply, as always when carrying out plumbing work, and close the drain to prevent certain parts (screws, nuts, etc.) from falling into it during handling. Open the taps to drain the water contained inside your pipes.
Next, remove the spigots from the faucet, i.e. the handles. To do this, unscrew the pellet placed on it (if there is one!) And insert a blade to sauté it carefully. Once done, unscrew the fixing screw of the handle of your faucet and remove the latter.
Now you can access the faucet head. With an adjustable wrench, unscrew the nut of the said head then finishes unscrewing it by hand. If you don’t succeed, use a little penetrating product and wait a few moments before starting again. That’s it, and you can take the next step!
Change The Damaged Seal On Your Faucet
Before going any further, be aware that the valve seal seat (which seals between the handles and the valve body) may be damaged and if so, it must be lapped.
To do this, use a lapping rod with a bur having the diameter of your valve seal and the thread of the same dimension as that of the head. Without forcing, screw the lapper onto the head of the handle. Turn the lapping wheel three turns, and it’s done!

And nothing could be simpler! If your seal is full, pry it off with a screwdriver or a flat knife and gently pull. If it is pierced, be sure to unscrew the nut that holds it before removing it.
Then clean the faucet head well and insert the new valve seal with your fingers.
Raise Your Faucet
Check that the head of your faucet is in the open position, then screw it back on by hand. Using an adjustable wrench, tighten the nut, holding the valve body firmly.
Then, put the handles back in their original location and secure them by screwing in their nut; do not forget to put back the covers or the coloured dots!
Finish by checking the tightness of your installation.
