The assembly of a urinal

By no means are urinals so popular that they would be a matter of course in private households. But the popularity to the urinal in their own homes is growing steadily. The installation of a urinal is not rocket science. The installation is similar to corresponding washbasin systems or toilets preferably via a pretext element. Below you will find a detailed installation instructions for mounting such a urinal.

Urinals in a private environment make sense

A urinal in a private household is definitely a gain in hygiene. Many "lords of creation" prefer to perform their smaller needs while standing. But even with the most credible protestations - it is permanently impossible to avoid urine injection.

Various urinal techniques

Because cleaning is still the task of the woman in many households, this of course represents an imposition. More and more living communities therefore decide to install a urinal. Here is to distinguish between different techniques:

  • Urinal with flushing
  • Urinal without flushing
  • Surface-mounted urinals
  • Urinals on a wall installation
  • Compromises between pre-wall and surface-mounted models, half-deep installed

Special features when installing a urinal

The biggest challenge when installing a urinal is the space. Because in the fewest apartments and houses urinals are prepared.

pipe sizes

The required nominal diameter DN of the drainage pipes for urinals corresponds to that of conventional drains such as sinks, kitchen sinks, washing machines etc., namely DN 50 (for comparison WC: DN 100). Thus, the drainage pipes for the urinal are usually hung on the drainage line of the next washbasin. Since the drainage pipes are laid horizontally from the urinal to the sink drain, the necessary line gradient of 0.5 cm / m, which corresponds to a gradient of 1: 200, must be observed.

The urinal flush

For rinsing, special flush valves are used, which open and close very slowly. Older flush valves opened abruptly, which could cause an audible pop in the line. Actuation is either via a feeler mechanism or a sensor (do not forget electrical installation). Many urinals are equally suitable for waterless and rinse water use, whereby the rinse water variant is privately preferred (more information under "Tips").

Circumference of a urinal

The urinal includes extensive accessories, which may vary depending on the model and system:

  • Wall unit
  • possibly corner valve
  • Flex hose
  • rinsing nozzle
  • actuator
  • Fixing material (dowels, screws, distance plates, rails, etc.)
  • urinal
  • Odor trap or siphon
  • Seals for the drain unit
  • various DN 50 pipes in different bends (degrees) and lengths

Urinals on a wall installation

The pre-wall elements have versions that can be walled in (wall-mounted cistern instructions, wet construction version), as well as cisterns for cladding (drywall version).

Step-by-step instructions for mounting a urinal

  • Wall unit
  • Urinal with all accessories
  • corner valve
  • Flex hose
  • Drainpipes and connections
  • Lubricant (rubber seal lips on pipes)
  • Hemp (sealing of external pipe threads)
  • drilling machine
  • Drills (stone, possibly metal)
  • spirit level
  • Meterstab
  • saw
  • ratcheting box
  • Ring wrench set (in some models also multi-tooth or Torx)
  • screwdriver
  • Wasserpumpenzange

1. Preparatory work

At the beginning, of course, is the urinal or toilet planning. This calculates the need for drainage drainage pipes.

2. Water supply and drainage (outflow)

Then water inlet and drainage pipes are laid. Make sure that the drainage pipes meet the minimum gradient. Many pipes have to be laid horizontally (to the sink drain). If you want a sensor-operated urinal flush, the corresponding electrical installation must also be carried out. You can also connect angle valve and flexible hose. Do not forget to turn off the water beforehand.

3. Installation of the front wall installation

Follow the installation instructions enclosed with the pre-wall element. In addition to wet and drywall versions, there are also freestanding models. You can already prepare the water inlet and outlet to the extent that the breakthroughs can be made by the pre-wall installation. Then disguise or wall up the pretext component.

4. Installation of the urinal

Drill the dowel holes for the urinal attachment. Rubber seal lips on the pipes are lubricated with the lubricant, outer pipe threads (water inlet) are wrapped with hemp. You also have to make the electrical installation now. Then slide the urinal onto the drain and attach it to the prepared brackets at the same time. In any case, follow the enclosed installation instructions for the urinal, as each urinal may differ in details.

Tips & Tricks

Urinals without flushing function with a barrier fluid that is relatively expensive. Similar to an oil film, this barrier liquid forms an odor-impermeable layer on the urine and avoids disturbing odors. Often, however, urinals are "misused" to dispose of the contents of cleaning buckets, for example. Then the whole barrier liquid is flushed out. In addition, the urinal ceramic must be regularly sealed (coated), which is also cost-sensitive. In the private sphere, the benefits and costs of such a urinal are therefore often not in an optimal relation.
