What To Do When Your Mains Have To Much Pressure

PSL recently was asked to advise on how to reduce the pressure coming from a standpipe when the customers had high pressure mains boosted by a pump.  After discussions within our R & D department a pressure releasing valve was fitted to this standpipe allowing our client to have an appropriate pressure with good flow.  This was another example of how PSL Fire & Safety are advisors and manufacturers to the industry.
