Repair kitchen faucet - how does it work?

If the fitting in the kitchen sink is defective, the question often arises as to whether a repair is worthwhile. When this makes sense, what you can do, and when you better replace the fitting at the sink, read this post.

repair options

Kitchen faucets are complex components that are usually difficult to disassemble. Repairs to individual parts of the valve are therefore not possible in many cases. In the event of an obvious defect of the fitting (it does not work anymore, there is no water or gurgling noises) you should definitely replace the fitting.

Leaking or dripping taps are usually no problem. They can be eliminated by changing the seal or cartridge. It is important to first differentiate between the types of faucets:

  • classic kitchen faucet with two knobs or
  • Single lever

Both have different repair options.

Classic fittings

Classic faucets with two knobs are comparatively simple, and also work according to simple principles. The water is simply passed through the valves in different amounts from the warm and cold side and mixed in the tap.

Because of the simple principle of operation also the possible damages are limited:

  • the fitting may calcify
  • the gaskets can become brittle over time
  • the seals can be damaged

All these things can be solved. All you have to do is remove the grips and remove the valve inserts with a 19-pin end. Underneath are the seals that can be replaced. Calcified parts can simply be lime-free in a vinegar bath. Instructions can be found here.

Single lever

With a single-lever mixer, the only option is to change the cartridge. However, replacement cartridges are not available for all mixer models, usually only for high-quality products. The new cartridge can easily be used by yourself.

Since replacement cartridges but can cost consistently 20 - 30 EUR, is also questionable whether the exchange is worthwhile.

In the case of a dripping tap, one could also try to swap the spigot. But that does not always succeed.

Tips & Tricks

If you change seals in the fitting, always change the same all Seals and also the O-rings. This is the only way they can ensure that all gaskets fulfill their function after all.
