What causes a blocked sewer?

If your toilets are regularly clogged and can no longer flush. If they are overflowing and you notice that your sinks are not draining properly and that you hear "gurgling" sounds every time you flush, the problem is most likely outside your home.

How can an outside manhole get blocked, a sewer overflow when they have much larger pipes than those in your houses?

The main causes of sewer overflows are

  • Using too much toilet paper at the same time (several flushes at the same time)
  • Non-biodegradable wipes or sanitary towels disposed of in the WC
  • Scale, lime and lye deposits that harden in the pipes and reduce their diameter 
  • Design problem: too small a slope between your internal installations and the external manhole or sewer.
  • Multiple 90° elbows that slow down the progression of the material.
  • Land subsidence causing breaks in the pipeline
  • Roots in the pipe.

If your outside manhole is blocked, there is no need to put destop in your toilet, only a professional unblocker can get you out of this situation.

Destop, bicarbonate of soda, grandmother's remedy... All these techniques are totally ineffective facing a clogged sewer problem. The reason is simple, the volume of water in the tube strongly dilutes whatever you are going to add. 

The most effective way to unblocking an overflowing drain is high-pressure hydrocleaning. This solution is fast, long-lasting and environmentally friendly. The unblocking experts offer a camera inspection (fixed price €250) if a root or breakage is suspected.

Who pays for the sewer that backs up or for the overflowing manhole?

It all depends on the location of the blockage. If it is outside your property, the municipality pays for the unblocking. If the blockage is in your property (outside manhole in your garden), the bill is for the owner or tenant.

We have written an article explaining how to determine whether the sewer problem is private or public

Frequently Asked Questions

Plumbers are our prescribers and privileged partners, they are specialists, but they do not have the equipment for this type of intervention because it requires a very specific investment (endoscopic camera, hydrocureuse, etc.).

Plumbers usually use our services for unblocking drains and sewers so that they can concentrate on their core business.

Hydrocleaning consists of unclogging and cleaning your pipes with a very high pressure "kärcher" equipped with specific ferrets. The nozzle goes up and cleans your pipes until it destroys the blockage.
