Ozone cleaner water supply: official advice on excessive water pressure
Anyone who connects an ozone cleaner to the mains water supply assumes that water can flow safely and without problems through the device. In most situations that is indeed the case. But there is a circumstance we have encountered more often than expected in recent times: water pressure that exceeds what the device can handle. The ozone cleaner is designed for a maximum water pressure of three bar. That is the pressure at which the device operates safely and reliably. In many homes and business premises in the Netherlands and Belgium, water pressure is well below that limit. But that is not the case everywhere. In new-build neighbourhoods, higher-floor apartments with pressure-boosting installations and some commercial premises, the water pressure at the connection point can be considerably higher. Water pressure is also not constant: it can vary by time of day, season and location within the pipe network. A connection that falls within the safe range at a quiet moment may temporarily deliver higher pressure during peak hours or after changes to the distribution network. We have seen cases where that peak pressure has led to leakage at the water connection of the device. That is not what we want, and it is not what our customers expect. Our decision is clear: we advise everyone to shut off the water supply to the ozone cleaner after each use. This is the most direct and reliable measure to prevent pressure-related damage while the investigation into a permanent technical solution continues. We understand that this is an extra step in the work routine. We are consciously asking that of our users because the alternative, damage from excessive pressure, is not an acceptable risk. Transparency is central to us: we share what we know, what we have seen and what we are doing to solve it. This article provides a complete overview of the pressure issue, the consequences of excessive water pressure, the measure we advise and the background to the investigation into a permanent solution. The accompanying articles in this silo go deeper into each component: the maximum pressure specification, the consequences of exceeding it, how to measure water pressure, why shutting off after use is the right measure and which technical solutions are available or being investigated. We will keep you informed as soon as there is new information.

Official update from Ozonreiniger on water pressure and safe use of the ozone cleaner. Advice, explanation and background on shutting off the water supply after use.
Water pressure and the ozone cleaner: what is happening, what we have decided and what it means for you
What is happening: pressure and specification
The ozone cleaner has a maximum working pressure specification of three bar. In certain environments, such as new-build locations with pressure-boosting installations or upper floors, pressure can be higher. More on the pressure specification: maximum water pressure ozone cleaner.
What we have seen
We have received cases where leakage occurred at the water connection while the device was not in use but remained under permanent pressure. The consequences are described in more detail in the article on excessive water pressure consequences ozone cleaner.
Our decision: shut off after use
Shut off the water supply to the ozone cleaner after each use. The full explanation is in the article on shut off water supply after use.
What this means for you in practice
For most users the impact is limited to one extra action: turning the tap off. Cleaning performance does not change. If you are unsure about the pressure at your location, read the article on measuring water pressure home or commercial.
What happens next: investigation into a permanent solution
We are investigating permanent technical solutions including a pressure reducer. More information: pressure reducer ozone cleaner solution. Questions? the contact page.
Summary
Shut off the water supply to the ozone cleaner after each use. Simple, immediately actionable, risk eliminated.
The ozone cleaner in use
The core function operates unchanged. More information on the ozone water machine. Full overview: ozone water knowledge guide.
