Wet and Dry Riser inspections in Greater Manchester & nationwide

 

All buildings which have a Wet or Dry Riser must comply with the standards BS5306 and BS9990/2015. A visual inspection is recommended every 6 months and a hydraulic pressure test every 12 months. Failure to do so may invalidate your insurance. Located in Oldham, our engineers work throughout Greater Manchester and across the UK. Contact us today for expert Wet and Dry Riser servicing and maintenance.

Annual pressure testing

 

For Dry Risers this 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 the 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 system failure due to inability to hold pressure for the recommended 15 minutes at 12 bar (at the inlet), a retest will be required.

 

For wet risers there are additional checks, on cleanliness of storage tanks, booster pumps and associated mechanical and electrical equipment.
