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?
