How can I change a kitchen faucet?

Whether in the kitchen or in the bathroom: the kitchen faucet on the sink controls the flow of water on the tap and ensures the desired temperature by mixing cold and warm water from two lines. Before you get a new faucet, however, you should check whether there is a boiler in the area. You can often find it under the sink in the kitchen. To process water from the boiler, you need a low-pressure tap.

To replace an old faucet with a new one, the water supply from both lines must first be interrupted. Then you loosen the old faucet at its connections and remove it before you attach the new faucet and seals to the sink and fasten the connections. Finally, you check whether the connections are really tight.

Note: If you live in a rented apartment, you should discuss the replacement of the tap with the landlord, if necessary. In some cases, the built-in fittings are part of the rented apartment equipment – then you are not allowed to replace them without prior consultation.

In order to be able to carry out the exchange safely, do not forget to turn off the corner valves on your wall so that no water can run in. Loosen the flexible hoses on the angle valve with an open-ended spanner or an English wrench.

Note: There may still be residual water in the hoses. To make sure that there is no more water running, you can also turn off the main tap.

The fitting is screwed to the bottom with a nut that you can easily loosen by hand. In order to be able to remove the faucet upwards, you have to unscrew one of the two flexible hoses upwards, otherwise, you will not be able to turn the nut off the hoses. Now all you have to do is pull the fitting out of the sink and unscrew the second flexible hose as well. You can reuse the two hoses for installing the new faucet.

Prepare your new fitting for installation by first inserting the sealing ring. This way the water does not run through the mounting hole. First screw in the blue-marked flexible hose for cold water, which is usually on the right, and then place the mixer on the sink. Then thread the second flexible hose for the hot water through the lock nut. Put the nut over the hose that has already been installed and screw it on together with the rubber buffer from below.

Then you screw the hot water hose to the faucet from above and screw on the lock nut by hand until the faucet is firmly seated. In the next step, you screw the flexible hoses back onto the angle valves. Make sure that the hoses are not kinked or twisted and tighten the nuts with an open-end wrench. Turn the corner valves back on and turn on the water.
