Title: Pressure relief valve in roof space
Post by: CraigD on February 09, 2021, 05:36:55 PM

This is an install of a pressure relief valve from a HWC in the roof space of a business.  The mains has a solenoid which gets switched off during closing hours for flood prevention but when it's opened (especially after long holidays), the valve gushes into a small trap (which has A/C drains also) and overflows into the roof space.  Firstly is this to code and secondly what is the solution?
