VIVAQUA guarantees a static pressure (= maximum pressure) between 2 and 10.5 bar. The pressure is not always the same, it varies according to the amount of water consumed by the customers: during the day, a lot of water is consumed, so the pressure is lower. At night, it is the opposite. The pressure is then at its peak (= static pressure)
For example, the static pressure is

• 7 bars at the Grand-Place at 1000 Brussels
• 6,6 bar at the Square Jean Rey at 1070 Brussels
• 4 bar at the Square du Solbosch at 1050 Brussels
• 6,4 bar at the Place de la Reine at 1030 Brussels

You can contact VIVAQUA to know the static pressure in your street.

VIVAQUA can also, at your request, measure the pressure available in your home for 7 days. Please note that you will be charged for this service.

Sometimes the pressure can drop unexpectedly, for example during works on the distribution network. It is often a temporary situation.

In large buildings, it may be necessary to install a device to boost the pressure in order to ensure sufficient pressure.

If the pressure is too high and could damage your private installation (for example, a water heater does generally not resist to a pressure higher than 7 bar), we advise you to install a device to reduce the pressure.

 

Flow is the amount of water (in m³ or litres) that flows from your tap during a given time (per second, per hour). The longer it takes to fill a container (a sink, a bucket, …), the lower the flow.

Pressure is a force exerted by water on a surface. To check if you have pressure, try stopping the water supply by plugging the tap with your finger. The easier it is, the less pressure there is. In drinking water distribution networks, pressure is usually measured in bar.

It may be a flow problem or a pressure problem.

Do you notice a lack of flow?

 

Open the tap after the VIVAQUA meter and check the flow there. If everything seems normal, the problem is likely to come from your private installation (tap filter clogged with limescale for example). In this case, we advise you to contact a plumber. If you notice a lack of flow at the tap after your meter, please contact our technical service (02 739 52 11 – 24 hours a day, seven days a week)

 

Do you notice a drop in pressure?

 

A lack of pressure is often temporary, due to works on the distribution network for example. Start by checking all your taps. If you notice a drop in pressure at only one tap, the problem is likely to come from your private installation (blocked pipe for example). If you notice a drop in pressure everywhere, check at your neighbours to see if they are having the same problem. In this case, please contact our technical service (02 739 52 11 – 24 hours a day, seven days a week).
