What it is
The Ariston 998069 is a three-way pressure gauge valve manufactured by Ariston for use in its standard water heater range. It sits in the water circuit and provides a gauge connection point alongside three flow ports, so system pressure can be read while flow is directed between the connected pipework. The valve body and spindle are the working parts, and the unit is supplied as a single assembly.
Signs this part needs replacing
- The pressure gauge reads zero, or the needle fluctuates when the system is running steadily.
- Water weeps from the valve body, the spindle or the gauge connection.
- The valve becomes stiff to turn, or turning it makes no difference to flow between the ports.
- Scale or debris in the water circuit causes the valve to stick or fail to seat.
- The gauge reading drifts away from the pressure shown elsewhere on the system.
Before you order
- Check the part number on the appliance data badge or in the manufacturer's documentation to confirm 998069 is the correct item.
- Inspect the joint faces and note whether a gasket or seal is needed to complete the repair.
- No GC number is listed for this part; identify it by the Ariston part number.
- This is not a gas-carrying component.
