Morco Products Safety Valve MCB2185

A safety valve for Morco Products FEB-series gas boilers, supplied under part number MCB2185. It is the pressure relief device that discharges water when system pressure exceeds the valve setting, protecting the boiler and connected pipework from over-pressurisation. The manufacturer reference for this item is N57G002M3.

• Water weeping or discharging continuously from the pressure relief discharge pipe when the system is cold
• System pressure repeatedly rising above the normal cold-fill reading, or refusing to hold pressure
• Visible scale, corrosion or debris around the valve body or outlet
• The valve fails to reseat after a discharge, leaving the outlet permanently wet
• Pressure gauge readings that fluctuate with no other cause found in the system

• Confirm the appliance model against the fit list above, as the valve is model-specific
• Note the valve connection size, thread type and pressure setting from the fitted component before ordering
• Check that the discharge pipework is clear and correctly routed before fitting a new valve
• Inspect the system for the underlying cause of the discharge, such as a failed expansion vessel or over-filling
