Dry Risers

The person responsible for a building or site is legally required to maintain all fire fighting equipment, including dry risers. A full annual pressure test and six monthly visual check is required.

Dry Riser Testing – Maintenance & Servicing

Dry Risers are a vital piece of fire protection equipment for buildings above 18 meters. They play a critical role in delivering considerable quantities of water in a high-rise building. They can however be prone to serious neglect and vandalism so it is important to have them regularly maintained and serviced. Nirvana Electrical Ltd engineers will carry out a full annual pressure test and six monthly visual check to the current British Standard Code of Practice BS9990: 2006 using our own dry riser testing appliance.

Dry Riser Testing – Annual Wet Test

Dry and wet risers are checked and pressure tested to 150 PSL or 10 bar for a minimum of 15 minutes. All insets and outlets are checked for leaks and any missing or faulty items replaced. Flow testing is also carried out. If any valves have to be replaced a further pressure test will be carried out before certification is issued.

Dry Riser Testing – Six Monthly Visual Test

This test involves a visual inspection only as required by BS9990: 2006 and any missing or damaged items are replaced.
