What it is
The 6 Bar Prv (Plastic Body) Loose Nut 3/4'' is a pressure relief valve from Popular Cylinder Spares, supplied as part of the cold water inlet controls range for unvented cylinders. It relieves excess pressure from the cylinder at a 6 bar setting. The valve has a plastic body and a 3/4'' loose nut connection.
Signs this part needs replacing
- Water discharging from the tundish or discharge pipe when the cylinder is not heating
- Continuous drip from the relief valve outlet
- The valve fails to reseat after it has operated
- Scale or debris visible on the valve seat or outlet
- Cylinder pressure drops or fluctuates with no other obvious cause
Before you order
- Confirm the existing valve is rated at 6 bar, as the relief valve setting must match the cylinder's pressure rating
- Check the connection is 3/4'' with a loose nut to suit the cylinder inlet assembly
- Check the cylinder make and model against the fit list above
- Work on unvented cylinders must be carried out by a competent person
