Water pipeline extension

Plans and needs

When constructing or reconstructing the water or sewers pipeline, it’s really important to predict what connectors you will need. Changing or improving these pipelines in the later period can be really expensive. Water and sewer pipelines are usually located in the wall, behind the tiles, rarely in the ground. Because of this their extensions can be expensive and complicated.

Alternative cheaper ways of extending the pipelines

While supplementing or moving the washing machine or the dish washer, or any other machine that uses water. We also have to pay attention on the sewer connectors.

It’s possible to add a T splitter on an already existing exit on the wall. It’s recommended to have a sink on the water installation. That way, an option to just disconnect that part from the water pipelines, and not the whole water grid exists. When a sink that has spots for hot and cold water is getting extended, we extend the connector for hot water as much for the cold, so they are leveled.


Rubber hose that goes from the wall to the machine, and it’s under pressure from the water. It should be as short as possible, not longer than 3-5 meters.

Before working on the water installations, close the water on the part you are working on, and spill as much as you can from the sink.

The sewer connector should be lower than the location of the machine you are connecting.

The hoses should be hidden behind a drawer or something similar.


When extending the hoses, it’s important to secure it so it doesn’t leak.

If we use a sliver it spins in and tightens on the thread.

Sliver and teflon are reeled the opposite way so they don’t spin.

Sliver and teflon are tightened as much as they can, but if we use rubbers for sealing they are just enough.
