What is the problem?

What manual flushing duty really costs

Germany stands for excellent drinking water. Yet in unused hotel pipes the danger grows quietly: water stagnates, and Legionella finds ideal conditions.

The hygiene-flushing duty requires an interval of 72 hours under VDI/DVGW 6023. Doing it manually means paying in staff hours, error risk and incomplete documentation.

up to 25,000 €

Fine per breach of the TrinkwV. On top of that comes the hotel operator's personal liability.

72 hours

Stagnation sets in after 72 hours at the latest. The hygiene flushing follows the recognised code of practice (VDI/DVGW 6023) — even for empty rooms.

Mandatory Legionella testing for large drinking-water systems under TrinkwV section 31. Gaps in the log are a regulatory offence.

How does Aqvior work?

How Aqvior takes over the hygiene-flushing duty

A smart shower fitting that recognises when flushing is needed, does it automatically and documents everything seamlessly. No cables. No bathroom renovation.

Self-powered

A built-in turbine generates power from the water flow. No cable, no electrician, no energy costs.

Automatic 72h flushing

The fitting detects unused showers and flushes on its own — log-compliant, with no human intervention.

Pause-to-soap

The guest stops the water while lathering up. 15–20% savings, no loss of comfort.

Dashboard monitoring

Real-time status of every shower at a glance. Which room was flushed, which is due — all seamlessly documented and available at any time.

The comparison

The solution that works

Manual rounds rely on trust. Existing systems require a complete bathroom renovation. Aqvior just runs — reliably, every day.

ERROR-PRONE

Manual flushing rounds

Everyone knows the problem: forgotten rounds, colleagues off sick, gaps in the paper log. It all depends on someone always being there and never forgetting.

COSTLY & IMPRACTICAL

Existing systems

Common hygiene-flushing systems require a complete bathroom renovation. Their industrial design doesn't fit a hotel. And the effort is out of all proportion to the result.

The team

We know the problem. Aqvior is our answer.

Founded in 2026 in Baden-Württemberg, Aqvior grew out of a simple observation. Over the past 20 years, little has changed in the hotel bathroom — except the colour of the tiles.

Our approach: technology does the work, the hotelier stays in control. We automate the hygiene-flushing duty that today is manual, error-prone and expensive.

FAQ

Frequently asked questions

The Aqvior shower fitting detects whether a shower has been used. After 72 hours without use, it flushes automatically — without anyone lifting a finger. Every hygiene flushing is logged in the web dashboard with timestamp, duration and water temperature.
Yes. The German Drinking Water Ordinance (TrinkwV) places responsibility on the operator — in hotels, that means you. Anyone who cannot present complete documentation during an inspection risks substantial fines, and in the event of health damage, even criminal consequences. With Aqvior, every hygiene flushing is documented automatically and available as a compliance report at any time.
No. Aqvior is fitted directly to the existing shower. No demolition work, no damaged tiles, no room taken out of service. Our team handles the complete installation in under an hour per room.
The web dashboard automatically keeps a complete digital drinking-water log for every shower. When an inspection comes, you log in, select the period and download the compliance report as a PDF.
Authorities can order the immediate closure of affected areas and impose fines. The reputational damage is hard to repair. Anyone who then cannot present complete documentation of the hygiene flushings is in a doubly bad position. With Aqvior, you always have that proof at hand.
Most systems on the market require a complete bathroom renovation. Aqvior does not. Your existing shower can be retrofitted easily — no demolition, no damaged tiles. The automatic hygiene flushing acts exactly where it counts: directly at the point of use.
