How Often Does Dry Riser Testing Need To Be Done?

If you have dry risers on your premises or you are responsible for them, it is important to know how regularly they have to be tested. This is a legal requirement and a failure to carry out testing on a suitable basis may lead to problems.

The legal requirement for dry riser testing

When it comes to dry riser testing, there is a legal requirement for the person that has been responsible for the site or building to test all the firefighting equipment. This includes dry riser testing, which has tests which need to be carried out annually and every six months. This means that you should be looking at your dry riser and testing it at least six months.

This is due to the British Standard Code Of Practice BS9990:2006 which states that a complete pressure test must be carried out every year and a visual check of all dry risers, for buildings which stand above 18 metres and less than 60 metres, must be carried out every six months. Buildings which lie above or below this height requirement require wet risers to be utilised.

Further information can be found within Clause 7 of the British Standard Code of Practice BS9990:2006. This states that the landing valve boxes, the drain valves, the landing valves and the inlets all must be inspected on a 6 month basis. The Clause also makes a recommendation that annual wet tests should be carried out. The main purpose of this test is to carry out examinations for leaks.

The British Standard Code Of Practice BS9990:2006 also makes provision for maintenance and all repair work to be carried out by a person of competence. This may mean hiring a registered or experienced professional to carry out all work with dry testing. In the long run, it may be worthwhile for a business to prove that they have a competent person employed on the payroll who is able to carry out these repairs and maintenance work.

Maintenance and Servicing of Dry Riser Testing

For a building that is taller than 18 metres, dry risers are crucial. They play an integral role in ensuring sizable amounts of water can be found in buildings that are classed as high rise. Unfortunately, these dry risers are commonly vandalised and neglected, so there is a need to ensure that they are reviewed on a regular basis. The legislation calls for a six month review of the dry risers but checking on them regularly can help to ensure that they are kept in good condition.

Yearly wet testing of Dry Risers

The testing of dry and wet risers involved them being pressure tested for a period of at least 15 minutes. The pressure test should take place at 150 PSL or to 10 bar. All of the outlets and inlets should be analysed for leaks and if there are any parts that are deemed to be faulty or missing, they should be replaced. At this time, it is also of benefit to carry out flow testing. If there is a need to replace any of the valves in the dry riser, an additional pressure test will have to be undertake to ensure that these valves are fit for purpose. Certification is now allowed to be passed until new valves have been reviewed.

Six monthly dry riser visual test

This test is straightforward, comprising only of a visual inspection and ensuring that any damaged or missing elements are replaced. While it may be helpful to have this test carried out by someone experienced that knows what they are looking for, it can be carried out by most employees.

Private testing of hydrants

There will be some premises of a larger size that will have hydrants on the premises. These also need to be tested and it is often best to leave the testing of these systems to a professional call Blaze Fire and Security Ltd on 08443350842 for all your dry riser testing requirements.
