Gutter drainage - this is how to install properly


The rain gutter collects rainfall that ends up on the roof. But if the gutter drainage via the downpipe and the other piping on the property does not work reliably, the foundation of the house and the garden are soaked.

Install drainage pipes for the gutter

The drainage pipes for gutter drainage on the property must be laid and assembled with the same care as other water pipes.

If they are just laid out loosely somewhere, the property can bottom out from underneath and the foundations of the house are just as damaged as the beds and lawns. In addition, stagnant water can severely damage the downpipes, especially in winter.

Place gravel bed to secure piping

The gutter, in which the gutter drainage pipes are laid, should on the one hand be laid deep enough and, on the other hand, should be well tamped and graveled.

Of course, the pipes must have the same diameter as the downpipe. If several downcomers are brought together, the drainage pipe should have a correspondingly larger diameter.

Drainage in the ditch

If the roof water runs into a drainage ditch, you should see how high the water is usually there. It does not help if you dig your gutter drainage very deep on the property when the drainpipe is under water permanently.

What to look for in gutter drainage?

  • Select downpipe of sufficient diameter
  • Secure drainage pipes securely together
  • Lay the pipes carefully
  • Avoid tight angles

Tips & Tricks

Avoid using any branches that are at right angles or steeper. Here you can collect dirt, small branches, leaves and bird nests. Then, of course, no more water runs off and in a real downpour, the property is flooded.

It is therefore better to use several lighter angles of 45 degrees instead of a 90 degree angle. This allows larger parts and dirt to run better.
