How to Install a Water Line

A life without running water is hardly imaginable today. Luckily, the days when you took your dirty laundry to the next stream are over. A washing machine and the dishwasher can be found today in almost every modern household.

How to Install a Washing Machine and Dishwasher

The connection of a washing machine is, if one observes a few rules, easily done by hand and is also perfect for laymen. If you follow the tips below, you will not have any problems with the proper connection of your devices. By the way, you also save money, when you do it on your own.

The Fresh Water Connection

Since the water pipe, which supplies the equipment permanently with fresh water, is constantly open in most cases, I strongly recommend you to use a so-called AquaStop valve. This valve is installed between the tap and the fresh water hose of the respective machine. The assembly is no more complicated than the direct connection of the hose.

Should the hose of the machine burst due to mechanical effects or its old age, or should it simply come loose, this rapid pressure drop will be detected by the valve. After that the valve shuts off the supply of fresh water and thus prevents flooding.

Without proper protection, the water runs in the worst case for several hours or even days, until you notice it. The damage caused by uncontrolled water splashes in the apartment, quickly exceeds the purchase price of a protection valve. Also the neighbours below you will thank you if the water spills through the chandelier!

AquaStop valves are available in both mechanical and electrical versions. Electrical systems open the supply line only when the connected device is actually in operation. These are usually already included in modern washing machines and are opened and closed by the software of the respective machine if necessary. Mechanical AquaStop valves are already available for about 30 euros and can be retrofitted to almost all washing machines and dishwashers.

How to Dispose Sewage Safely

What counts for the supply of fresh water is also important for the sewage. Also on the other end of the machine it is advisable to make some precautions to avoid flooding.

If there is a separate drain at the installation site of the machine, it is recommended to use it. If there is no separate drain, you should use a siphon, which is the curved tube under the sink. A siphon usually has a smaller second entrance, which is closed with a protective cap. After you've loosened this cap, you can connect the waste water hose of the dish- or washing machine to this opening. This allows the device to pump the wastewater directly into the sewer pipe. When using the siphon, it is important to connect the device's hose with a clamp. Only when using a suitable hose clamp, the hose can't slip! Here it's really important to use a matching hose clamp in the right size. Silicone, tape and other adhesives are completely out of place here!

It's best not to put the drain hose loose in the sink or bathtub. What at first looks like a viable emergency solution is quickly becoming a problem. Because of pets, children or other influences, the hose could slip and maybe ends up on the floor in the room. In addition, no one likes lying in a bathtub in which the sewage of the washing machine runs in, at the same time.

The right Siphon

The siphon is quite inconspicuous, but fulfills several tasks in the drainage. It connects the sink and other equipment to the local sewage network and prevents rising odours from the sewers. Because of the loop of the siphon, always a little water remains in it and closes the sewer airtight from the apartment. Without it, unpleasant odours, or even worse, animals would stream into the apartment. That's why it's recommended, when buying a siphon, not to necessarily use the cheapest from the furniture store, because they are usually made of less high quality material and tend to leak after just a few years.
