What it is
The Broag Filling and Drain Cock 1/2 is a 1/2 inch valve used on Broag commercial boiler installations for filling, draining and isolating the system water circuit. It is supplied as a Broag spare part for the GAS 320 ACE and GAS 620 ACE ranges.
Signs this part needs replacing
- Water weeping or dripping from the valve body or spindle when closed
- The valve will not shut off fully, so the system cannot be isolated or drained cleanly
- The operating handle or spindle is seized, stiff or rounded off
- Mineral scale or corrosion visible around the seat or outlet
- Difficulty holding system pressure during filling
Before you order
- Confirm the connection size required is 1/2 inch
- Check the appliance model and variant against the fit list above
- Inspect the surrounding pipework and seals for damage before fitting
- Isolate and drain the boiler/system before removing the existing valve
