Severe penalties could be imposed should the dry riser fail to work in the event of an emergency. Risers should therefore be inspected and serviced annually to BS9990:2006.


The annual testing and maintenance of both Dry and Wet Risers is the responsibility of the property owners or managing agents.

British Standard 9990:2006 recommends that the system is visually inspected every 6 months, and serviced annually to ensure that the equipment is ready for immediate use in an emergency.

In addition, it is recommended that a ‘full wet test’ be carried out annually, comprising of a wet pressure test to 150 PSI or 10 Bar subjecting the mains to a full working test.


Buildings above 18 metres tall will have dry risers, Buildings above 60 metres will have wet risers.
