What it is

The C780 is a pressure reducing valve with an integral strainer, manufactured by Andrews for its water heater range. It regulates incoming supply pressure to a stable outlet pressure and traps debris before it reaches the appliance. The valve has a 3/4 inch connection.

Signs this part needs replacing

  • Outlet pressure creeping above or falling below the set value
  • Reduced flow or a pressure drop across the valve caused by a blocked strainer
  • Water weeping from the valve body, bonnet or adjuster
  • Banging or water hammer in the pipework downstream of the valve
  • Pressure gauge readings fluctuating without any change in demand

Before you order

  • Confirm your appliance model against the fit list above
  • Check that the connection size required is 3/4 inch
  • Verify the incoming supply pressure and the outlet setting needed for the system
  • Isolate and depressurise the water supply before removal
