Drinking water must be protected in drinking water pipelines. DIN EN 1717 subdivides fluids into five liquid categories based on the potential hazards for the person who might be exposed to this water. Honeywell offers the right solution for every liquid category.

In order to maintain drinking water quality it is important to protect against the flushing through of foreign particles, such as rust or sand, for example. Honeywell offer a patented, reverse rinsing system, which reliably ensures an absolutely clean, particle free water supply which also serves to protect the entire water supply installation from malfunctions and corrosion damage and prolong component longevity.

Pressure reducing valves and pressure regulators protect pipes, valves and system components from damage caused by excessive water pressure. They provide effective system protection, particularly at night when low consumption increases the system pressure, or in the event of pressure surges and water impacts.
