Ferroli 39813030 Safety Valve C/W Manifold

The Ferroli 39813030 is a safety valve supplied complete with its manifold. It is a pressure-relief component used in Ferroli heating appliances, where it opens to discharge water if system pressure rises beyond the valve's set limit, protecting the heat exchanger and other components from over-pressure damage. The manifold carries the valve body and provides the connection point to the appliance pipework.

• Water continually dripping or discharging from the valve outlet or relief pipe when the system is at normal pressure.
• System pressure falling repeatedly and needing frequent top-ups, with no visible leak elsewhere on the circuit.
• The valve failing to reseat after it has lifted, leaving a steady weep from the discharge point.
• Scale, sludge or debris holding the valve seat open, causing a constant trickle.
• Visible corrosion, cracking or deformation around the valve body or manifold joint.

• Confirm the part number 39813030 against the appliance's manual or data plate before ordering.
• Check the appliance model and, where shown, the GC number so the correct variant is identified.
• Inspect the manifold joint and any sealing washers on removal, as these may need renewing at the same time.
