Fitting and removal of a wash-hand basin tap

Installing or repairing a washbasin tap doesn’t have to mean calling a plumber. In many cases, you can handle it yourself — as long as you know where to start and what to pay attention to. Check out our tips — you might be able to do it on your own!

Key information at a glance

  • Always turn off the water supply before dismantling the tap.
  • The most common cause of failure is a worn cartridge or seals.
  • You’ll need basic tools for installation (spanner, adjustable wrench, Allen key).
  • After installation, always check the entire system for leaks.


When and how to dismantle a washbasin tap?

A washbasin tap is dismantled when there is a problem with its operation or when you want to clean it thoroughly. This usually applies to issues such as dripping, reduced water pressure, or uneven handle operation.

Before starting the dismantling process, prepare your workspace and tools. This will help you avoid searching for parts during the job.

Before dismantling the tap:

  • turn off the water supply,
  • secure the drain (e.g. with a plug or cloth),
  • prepare a container for leftover water,
  • use protected tools (e.g. with rubber) to avoid scratching the surface.

Dismantling usually involves removing the handle, unscrewing the cover and accessing the cartridge. This is most often responsible for tap issues.


How to replace the cartridge in a washbasin tap?

Replacing the cartridge is necessary when the tap leaks, is difficult to turn or does not maintain the set temperature. It is one of the most common repairs you can carry out yourself.

The replacement process is simple but requires precision and the right parts.

Replacement steps:

  • remove the cap on the handle,
  • unscrew the screw (usually with an Allen key),
  • remove the handle and cover,
  • unscrew the retaining nut,
  • remove the old cartridge and install a new one.

The new cartridge must be compatible with the tap model. It’s best to choose a part from the same manufacturer to avoid fitting issues.


Which valve and thread to choose for a washbasin tap?

The thread and valve must match your installation, otherwise the connection won’t be tight. In most cases, standard solutions are used, but it’s worth checking before purchase.

Most common solutions:

  • 3/8 inch thread in connection hoses,
  • angle valves suited to wall installation,
  • compatibility of all components (tap, hoses, valves).

If the components don’t match, installation problems or leaks may occur. That’s why it’s best to choose parts as a complete set.


How to install a washbasin tap step by step?

Installation involves properly connecting the tap to the system and securely fixing it to the washbasin. The most important thing is to follow the correct order and work precisely.

Before starting, check the condition of the installation and make sure there are no leaks.

Installation process:

  • Screw the hoses onto the tap body.
  • Install the mounting bolt and stabilising elements.
  • Place the tap in the washbasin hole.
  • From below, fit the seals and mounting elements.
  • Tighten everything and connect the hoses to the valves.

Finally, turn on the water and check for leaks. This is when installation errors become visible.


At what height should a washbasin tap be installed?

The installation height depends on the type of washbasin and the tap, but there are recommended ranges that ensure comfortable use. It’s important that the water stream hits the centre of the basin and doesn’t splash.

In practice, the following values are used:

  • Deck-mounted tap – the spout should be approx. 10–15 cm above the edge of the basin.
  • Wall-mounted tap – installation approx. 20–25 cm above the top edge of the basin.
  • Countertop basin – spout approx. 20–30 cm above the rim or wall-mounted tap at 25–30 cm.

It’s also important to consider the spout reach — the water stream should fall roughly in the centre of the drain.


What mistakes most often occur during tap installation?

The most common mistakes result from rushing or lack of precision. Even small errors can lead to leaks or faster wear of components.

Most common issues:

  • loose connections,
  • missing or incorrectly fitted seals,
  • over-tightening (thread damage),
  • incorrect hoses,
  • no leak test after installation.

A properly done installation means long-term use without the need for corrections.


Checklist: installation and dismantling without errors

  • Turn off the water supply before starting work.
  • Prepare tools and secure the drain.
  • Choose compatible components (thread, valves, hoses).
  • Install in the correct order.
  • After finishing, check the system for leaks.

FAQ

Does the length of the spout matter during installation?

Yes, it determines where the water stream falls — it should match the depth of the basin.

Can you install a tap yourself without experience?

Yes, in simple installations it’s possible if you follow the correct order and work carefully.

Does the type of washbasin affect the choice of tap?

Yes, some models are suited to countertop basins, others to inset or furniture basins.
