Ideal Safety Valve 1/2M 3 Bar Pushfit 178088

The Ideal 178088 is a safety valve rated at 3 bar, supplied with a 1/2 inch male connection and a pushfit fitting. It is listed by the manufacturer under the temperature and pressure relief valve category, so its job is to open and discharge when pressure or temperature inside the appliance rises beyond the set limit, protecting the unit and the pipework from over-pressurisation.

It is an Ideal spare intended for Ideal Commercial appliances, including heat interface units where a controlled relief point is part of the primary circuit design.

• Water discharging from the valve outlet when the system is at normal operating pressure
• The appliance losing pressure repeatedly and needing regular top-ups
• The valve failing to reseat after it has lifted, leaving a constant weep
• Scale, corrosion or debris visible around the valve seat or outlet
• Pressure or temperature readings climbing past the normal working range before the valve operates

• Check the part number on the existing valve against 178088 before ordering
• Note the alternative number 1782876, which may appear on older stock or documentation
• Confirm the appliance model and, where shown, the GC number against the compatibility list
• Check the condition of the connection and any seal at the valve outlet, as these are disturbed during replacement
