Measuring water pressure home or commercial: how to check the pressure at your connection
Many users of the ozone cleaner do not know what the water pressure is at their connection. That is understandable: for most household appliances it does not matter, and water pressure is something you do not normally measure. But for the ozone cleaner, with a maximum working pressure of three bar, it is worthwhile knowing whether the connection falls within that limit. Fortunately, measuring water pressure is simple, inexpensive and can be done without technical expertise. You need one tool: a water pressure gauge. This instrument is available at virtually every DIY store for less than fifteen euros. It is connected to a tap outlet or a drain point in the pipe network and immediately shows the static water pressure. The measurement takes literally a few seconds. For a reliable picture of the pressure at your location it is useful to measure at multiple moments. Water pressure varies throughout the day: at night, when consumption is low, pressure is generally higher than during the day. A measurement at a quiet moment gives the highest pressure you can expect at that connection. That is the pressure relevant for assessing the risk to the ozone cleaner. For home users the measurement is straightforward: connect the gauge to an outdoor tap, the valve under the washbasin or the connection point of the ozone cleaner itself. Open the tap and read the value on the gauge. A value below three bar indicates the connection falls within the ozone cleaner's specification. A value above three bar is a signal that action is needed, in the form of shutting off after use or installing a pressure reducer. For commercial users in office buildings, hospitals, hotels or other professional environments the situation is slightly more complex. In these environments water pressure is often centrally regulated by the building manager or technical services. The pressure at the connection point of the ozone cleaner may differ from the pressure shown at the building's water meter. In-building pressure boosters or pressure-reducing valve chains can influence pressure per floor or per zone. The most reliable method is measuring directly at the connection point where the ozone cleaner is used. If measuring is not possible, consulting the building manager or technical services is a good second step. They generally have an overview of pressure regulation in the building and can indicate whether the connection point falls within the specification. This article describes how to measure water pressure in a domestic or commercial environment, what tools you need and how to interpret measurement results in the context of safe use of the ozone cleaner.

Practical explanation of measuring water pressure at home or commercially: what tools you need, how to measure and how to interpret results.
Measuring water pressure: a practical guide for home and commercial use
What you need
A water pressure gauge with standard 3/4 inch fitting. Available at the DIY store for five to fifteen euros. Context: water supply ozone cleaner pressure update.
Where and when to measure
Measure directly at the ozone cleaner's connection point, at a quiet moment when pressure is highest. More on the maximum pressure specification: maximum water pressure ozone cleaner.
Interpreting results
Below three bar: safe, shutting off after use remains good practice. Above three bar: action required. Shut off: shut off water supply after use. Pressure reducer: pressure reducer ozone cleaner solution.
Commercial environments
In buildings with central water installation, the building manager can advise on pressure per floor. Questions? the contact page.
The ozone cleaner in use
The ozone water machine functions normally at pressures well below three bar. More: ozone water knowledge guide.
