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 cabinet and do for corrosion
  • 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?


A Dry Riser is a network of pipes running up inside of taller buildings (or ones with restricted access) to enable the fire brigade to pump water to areas within the building when tackling fires high up.

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).
