Drain of the washing machine

Washing machines can be found in every household today. The connections are largely the same in new apartments and houses. In the case of old and older existing buildings, however, there may be significant deviations from the current standards. This not only applies to the water inlet, but also to the drainage of the washing machine.

Washing machines have a lot in common

Even if there are numerous manufacturers of washing machines who offer different models, they all have one thing in common. The washing machine dimensions are almost identical: there are front and top loaders. They are available in widths with the larger standard dimensions and smaller standard dimensions.

Standard equipment of washing machines

Of course, some manufacturers also offer various special sizes so that the optimal washing machine is available for every need. When it comes to the keys of a washing machine, it's even easier:

  • Power cord with plug (220 V)
  • Intake
  • Outlet
  • Inlet hose
  • Drain hose (with or without Aquastop)

Hoses are included with new devices

The hoses are included as accessories for a new washing machine. With some providers you can choose between straight and angled hoses (at the connections). The drainage hose is always constructed in the same way.

Connection of inlet and outlet

The drain hose is screwed tight on the washing machine side. On the wall side, the mostly corrugated, soft hose (with the exception of the drainage hose with Aquastop) ends in a long piece of rubber pipe, which tapers towards the end.

The outflow in today's usual outflows

When you connect your washing machine, this hose end is simply plugged into the existing drain. The drains for washing machines used since at least the 1990s are largely standardized on the building side. Largely because there have been and still are modifications and special requests.

Washing machine drains in different positions

If the washing machine connections are in the bathroom, they are often a little apart from other fittings such as the washbasin. Then an extra connection option is kept ready (water, drainage, electricity). But it also happens that there are no connections.

Drain without siphon

Then there are different options again. The washing machines are usually also supplied with a bend that can be attached to the drainage hose. Attach this to the wall-facing end of the drainage hose, it forms a hook. In principle, you can hang the drainage hose anywhere you need it:

  • sink
  • Shower tray
  • bathtub
  • Toilet

When there is no drain for the washing machine

But if you want a permanent connection, there are two options: on the one hand, you can replace your siphon for the wash basin with a suitable insert that is equipped with a washing machine drain.

New installation in the ground

However, if you have to move the washing machine somewhere else and if it is a residential property, you can of course lay a complete drain. Since bathroom floors are usually raised, you can either mount it in the floor or build a pre-wall element up to the location of the washing machine.

Installation in a pre-wall element

Pre-wall elements are now also used for the installation of the other sanitary facilities. However, you have to keep in mind that certain lengths must not be exceeded, otherwise you will need an extra vent for the drain. The slope must also correspond to the building standards. If you want to lay a drain pipe in the ground, you have to pay attention to other installations such as underfloor heating.

Tips & Tricks Especially when the connection options do not meet current standards, there are a wide variety of adapter pieces that you can convert existing drains so that you can also connect the washing machine there. Before you look for suitable components in a specialist retailer, you should photograph your drainage options and show them to the specialist salesperson. The more detailed he knows, the better and more accurately he can advise you.
