Regular maintenance of surface hydrants, underground hydrants and wall hydrants is enormously important. They ensure a reliable and independent water supply for the fire brigade in case of emergency.
Important: Above-ground and underground hydrants are connected to the public water supply network. Therefore, drinking water protection must always be taken into account. If you have any questions, please contact our experts.
What kind of hydrants exist?
There are wall hydrants as well as underground and surface hydrants. A wall hydrant is suitable for use by a layperson as well as by the fire brigade. These are permanently installed water tapping points in buildings. Underground and surface hydrants are used exclusively by the fire brigade to supply water in an emergency.
An underground hydrant is sunk into the ground, e.g. on a road or in a car park, and marked with signs. In the event of an emergency, the fire brigade can use a standpipe to establish a water supply. In contrast, an above-ground hydrant is a permanently installed fitting for drawing water for firefighting. They are often found in residential complexes, city centres or industrial facilities and have different connections (A, B or C).
Wall hydrant maintenance
Wall hydrants with dry risers are to be maintained every two years. All other wall hydrants must be inspected once a year. This is based on DIN EN 671-3 and DIN 14462.
Maintenance of surface hydrants & underground hydrants
The maintenance of above-ground hydrants and underground hydrants is necessary on a regular basis - at least once a year. Maintenance must be carried out by a competent person in accordance with DIN EN 14339 (underground hydrants with nominal sizes DN 80 and DN 100) and DIN EN 14384 (above-ground hydrants with nominal sizes DN 80, DN 100, DN 150 and PN 16). In addition, the results of the testing of the above-ground or underground hydrant must be recorded in a test book.
In addition, depending on the federal state, an inspection of above-ground and underground hydrants by an expert is required every three to six years in accordance with the Technical Inspection Regulations (TPrüfVO for short).
