Alpha Pressure Relief Valve 3 Bar 1.028643

The Alpha 3 bar pressure relief valve is a safety component used across the Eco, InTec ErP and InTec ranges. It sits in the closed heating circuit and opens proportionally once system pressure reaches its set rating, discharging water to relieve the excess. This controlled release protects the appliance and the wider system from the damage that uncontrolled over-pressure can cause.

• Water discharging from the pressure relief discharge pipe when the system is not overheating or over-pressurised.
• System pressure dropping repeatedly, requiring frequent topping up at the filling loop.
• The valve failing to reseat after it has lifted, leaving a continuous drip or weep.
• Scale or debris visible around the valve seat, or the valve body showing corrosion or staining.
• Pressure gauge readings climbing beyond the normal cold and hot operating range for the appliance.

• Check the GC number and appliance serial plate to confirm the correct valve for your model.
• Confirm the existing valve rating matches the 3 bar specification before fitting.
• Inspect the sealing washer or gasket at the valve connection and replace it if it is compressed or perished.
• Confirm the discharge pipework is clear and correctly routed before returning the appliance to service.
