Cornwall dry Riser and fire hydrant testing services by Advanced Fire & Security Cornwall.
Dry risers are tested and pressurised to a testing pressure of 12 bar and held at this pressure for a minimum of 15 minutes. All dry riser inlets and outlets are checked for leaks and any missing or faulty items replaced. Flow testing is also carried out on the system. If any system parts need to be replaced a further pressure test will need to be carried out to allow certification is issued.
