See how they work

Greywater interface tanks are the smart answer to integrating greywater outlets into a vacuum piping system. See how we make that possible!

Air inlet

allows air to exit the tank when it's filling up, and to enter the tank when the discharge valve opens. The air pushes greywater from the tank into the piping through the valve.

Overflow valve

Blocks the air inlet pipe if water rises up through it. This eliminates the risk of overflow spills from the air inlet.

Greywater inlet

accepts standard size hoses and pipes. Connects sinks, washing machines, showers etc. to the vacuum system.

Level sensor

opens and closes the valve at preset water levels. The process is completely automated.

Stainless steel

corrosion resistant material. Prevents damage from long-term use.

Vacuum interface valve

lets greywater and air enter the vacuum system safely. The valve only stays open for a few seconds at a time.
