Attach a washing machine to the sink

Washing machine connections are by no means standard. For this reason, the washing machines should usually be connected as circumstances permit. This may also mean that you need to connect a washing machine to the sink.

This is needed for a washing machine connection

If the special connections are available, it is no big deal to connect a washing machine. However, if this washing machine connection is missing, it usually gets a bit more complicated. All in all, the following connection requirements for a washing machine are required:

  • water supply
  • water drainage
  • Electricity 230V

Special features of power connections in bathrooms and other wet rooms

If you want to connect a washing machine to the sink, this usually means bathroom according to old standards, in which the corresponding power supply options are missing. If electricity is available, then usually at the level of the mirrors or somewhere similar high up - always so far away that no electrical equipment in the water (bathtub, for example) can fall. That should be taken into account in any case.

Electrical installations exclusively by a specialist!

To make it really safe, so you should install a power outlet that can actually be used only for a washing machine (lockable), also a wet room socket is also strongly recommended. You should only install the power connection if you have sound electrical engineering knowledge and know all connection principles for washing machines and the like in humid rooms.

Requirements for corner valve and siphon

For the aforementioned reasons, no corresponding branch will find itself on the siphon. Likewise, the angle valve will be easy. Special features are also to be considered with the siphon. So the connection must have an odor trap. The whole thing would be a dip tube siphon with side ¾-inch connection. Meanwhile, the angle valve can be a conventional combi angle valve (also double spindle or duo check valve).

If all connections can be realized, there is nothing standing in the way of the washing machine connection on the sink.

Step-by-step instructions for connecting a washing machine to the sink

  • appropriate siphon with side washing machine branch and odor trap
  • double angle valve (two connection threads)
  • Electrical installation material for damp rooms (including corresponding surface-mounted socket)
  • Hemp for wrapping the pipe threads
  • Wasserpumpenzange
  • possibly larger pipe wrench
  • possibly fork-ring wrench set
  • possibly screwdriver for hose clamps
  • spirit level
  • Tool for electrical installations
  • Bucket for catching water (change of siphon)

1. Prepare all connections

First, all connections are laid or prepared. The installation for the current should only be carried out if you know enough about it. Then take out the old siphon under the sink and replace it with the new siphon with odor trap and side outlet. The external threads wrap around you with hemp.

To replace the simple shut-off valve, you must first turn off the main water tap. In multi-family houses, you first have to inform the other parties. Then dismantle the old angle valve and replace it with the new double valve.

2. Now connect the washing machine under the sink

If it is a new device, you must first remove the transport locks of the washing machine. Then connect the two supplied hoses to the washing machine. In a conventional washing machine, the corrugated hose is for the waste water. For Aquastop systems, the one with the plastic box is for the water inlet.

Now bring the washing machine to its final position so that you can align the washing machine. You can turn the legs on or off while checking the level with the spirit level on the top of the machine. Finally, turn the water on the shut-off valve and plug in the mains plug. Now only a test run is missing, if everything is tight.

Tips & Tricks

You may be able to dispense with replacing the siphon. All new washing machines are supplied with a sheet into which the waste water hose can be inserted. Then the free end is bent like a hook that you can hook into any sink or toilet. However, you must then hang the hose again and again during washing if it is otherwise not visible.
