Dry Risers & Wet Risers

Dry Riser Repair

A Dry Riser is a system of valves and pipework which enables the Fire Service to pump water on to the uppeer floors of a building. A Wet Riser is a system of valves and pipework which are kept permanetly charged with water.


A dry riser system is an empty pipe running up the inside of a building which can be connected to by firefighters and used as a pressurised water system. There will be inlet connections on the outside of the building – or in fire escape areas – for the fire services to access, allowing the water to be pumped up to valves on upper floors on the inside.
This makes things easier for firefighters who are tackling a blaze in a building with multiple floors, with most systems installed up to a max of 50m above the fire service access level.
These systems are designed to provide pressure on the upper floors of a building, so need to be planned into the construction of a building carefully.


We pride ourselves on providing the best possible service to our clients with competitive rates. We always deliver our service to the best possible standard complyin with legal requirements.

We carry out dry riser installations across the UK including London, Cambridge, Milton Keynes, Northampton, Essex, Norwich, Nottingham & Derby.

Every 12 months a water test should be carried out to 12 bar for 15 minutes.

Dry riser testing is a legal requirement dictated by BS9990:2015 which is the British Standard that details requirements for a dry riser test and maintenance in the UK.

Dry Riser testing frequency and dry riser maintenance requirements. Durcan Dry Risers know the answer and are here to help.

The 6 monthly visual check which is primarily an anti theft or anti vandalism check. This should be carried out by a competent person with the records stored in a safe place, should they be required by the local authorities.

Dry Riser Pressure Test

We offer installation, comissioning, servicing / maintenance and repairs for all types of dry risers across the UK.


6 Month Visual Inspection Consists Of  Checking The Following - 

  • Exercise all valves and leave them secured in the closed position (checking strap and lock if required)
  • All outlet washers
  • For damaged and missing blank caps and chains
  • That all hand wheels and nuts are undamaged and intact
  • Landing outlet valves open freely and are undamaged

  • The inlet breaching valve springs and rubbers are free moving and in good condition
  • The inlet/outlet cabinet glass
  • All required sinage is present and correct


Annual Pressure Testing

Dry Risers - An annual pressure test entails connecting the inlet to a pump and water supply. The system is then completely charged with water to a pressure of 12 bar, measured at inlet for a period of at least 15 minutes. During this period an inspection is made to ensure that there is no leakage of water at any of the joints or landing valves. Once the pressure test is completed the system must be drained so that it is left ready for immediate use. In the event of the system failing we are able to carry out dry riser tests using air to locate the origin of any leaks without causing any water damage, once the repair is completed we could carry out a full dry riser pressure test using water inline with British Standards.

Wet Risers - For Wet Riser Sytems there are additional checks, on cleanliness of storage tanks, booster pumps and associated mechanical and electrical equipment.

What is Dry Riser Servicing?

The buildings Responsible Person (or RP) is legally required to ensure the system is maintained to BS 9990:2006 code of practice which means a full annual pressure test plus a six monthly visual check for dry risers in buildings over 18 metres but below 60 metres (anything over 60 metres or 18 stories must have wet risers).
