Small problems solved quickly - important questions and answers


My vacuum valve does not close - what can I do?

If the vacuum valve does not close, there may be various causes:

  • Check whether all yellow caps on the compact controller are removed.
  • Check whether there is water in the connecting hoses.
  • Disconnect the hose between the compact control and the vacuum valve. The valve should now close. If it still does not close, the valve is blocked from the inside: Remove the object in the valve.

My chamber does not provide suction - what could be the reason for this?

There may be various reasons for this: Either the vacuum is too low or the hose is not connected properly. Also check whether the pressure cap is correctly fitted. A blockage in the reservoir or in the valve can also restrict the suction power.

Can I adjust the vacuum in my system to different workloads?

Yes, the vacuum can be regulated. Please contact us and we will explain the possibilities to you.

How many households can be connected to one chamber?

Depending on the number of residents, we can offer various solutions. We will be happy to assist you in this regard.

Is vacuum technology loud?

No, it is rather an unusual noise during the suction process.

Can I also connect normal toilets to a vacuum sewer?

Yes, toilets can be connected via a house collection chamber.


Why can't anything leak out with a vacuum system?

Since the entire pipeline network is continuously under negative pressure, the wastewater is directly extracted by the pumping power and does not remain in the pipes.

Why is wastewater vacuum technology suitable for conservation areas?

Because the pipes have small diameters, the interference with the soil is minimal, as only a minimum of soil excavation is required. In addition, exfiltration does not occur even in the event of a pipe burst - the system is leak-proof.

Does vacuum technology save water?

Since wastewater is transported by means of negative pressure, vacuum sewer systems eliminate the need for regular flushing of the pipes, which is necessary with conventional systems. Vacuum toilets also require only small amounts of water compared to conventional toilets, reducing consumption many times over.

Can wastewater vacuum technology be used for contaminated water?

Whether industrial wastewater or radioactive wastewater: vacuum technology can be used to transport contaminated water separately and absolutely leak-proof.


Is a vacuum system cheaper than a conventional system?

Yes! Because there are significantly lower costs for pipe laying than for a gravity sewer. A vacuum system also does not require additional pumping stations or maintenance manholes, we can simply transport wastewater uphill.
