What it is
The ONYX 80L BLUE POTABLE VESSEL 1 2Bar w FEET is an 80-litre potable water expansion vessel from Onyx, finished in blue and supplied with mounting feet. It absorbs the expansion of heated potable water so that system pressure does not rise unchecked as the water warms. It sits within the Onyx range of pressure vessels and accessories.
Signs this part needs replacing
- Water discharging from the expansion relief valve as the system heats up
- System pressure rising sharply when hot and falling back when cold
- Water weeping from the air charging valve, indicating a failed internal diaphragm
- Corrosion, pitting or water pooling around the base of the vessel
- Pressure gauge readings that swing widely through each heating cycle
Before you order
- Confirm the 80-litre capacity and the 1 2Bar pressure figure suit the existing vessel and the system it serves
- Check the connection size and thread on the existing installation against the vessel being fitted
- Confirm the installation is a potable water system rather than a sealed heating circuit
- Allow clearance for the vessel body and for the feet mounting position
