How dry-riser testing is carried out
Our engineer pumps water into the riser at a pressure of 10 bars for around fifteen minutes to ensure there are no leaks. A loss of pressure is typically due to leakages caused by corrosion or faulty components, which would require urgent replacement. Once the issue is rectified, our engineer repeats the testing process to confirm the system is operational.
Our engineer tests a number of parts subject to corrosion and/or breakage. This includes the dry-riser’s washers, valves, nuts, doors, springs and rubbers. Our engineer is typically able to put right any discovered faults immediately. If this is not possible our engineer orders the required parts on your behalf. Our engineer returns to your premises at a later date in order to rectify the problem by installing the required parts
