The hydro-pneumatic accumulator fitted on a cold water booster set in a roof top failed due to hydraulic shock caused by a lack of regular maintenance. The fact that the vessel failed was bad enough but the ensuing flooding of the top two floors caused £1000’s of damage. Routine regular maintenance would have avoided this situation.
