What it is
The Broag 51143 is a water pressure switch supplied as a boiler control component. It is a Broag Commercial spare part intended for use in the GAS 350S and GAS 450S commercial boiler range, where it monitors water pressure within the appliance and signals the control system accordingly.
Signs this part needs replacing
- Boiler fails to fire or runs only intermittently despite the system holding pressure
- Boiler locks out or shuts down during a demand for heat or hot water
- Fault codes or warning indications relating to water pressure appearing on the appliance controls
- Erratic switching behaviour, with the boiler cutting in and out without a change in system pressure
Before you order
- Confirm the appliance model is the Broag Commercial GAS 350S or GAS 450S
- Check the existing switch and its connections against the part number 51143
- Verify the fault is traced to the pressure switch and not to low system pressure, a blocked sensing line or a wiring fault
- Isolate the appliance and depressurise as required before fitting
