What it is
The Pressure Relief Manifold 8 Bar (New Type) is a cold water inlet control component supplied by Popular Cylinder Spares for unvented cylinder installations. It combines the pressure relief function within the cylinder's cold water inlet control group, opening at 8 bar to discharge excess pressure safely. This is the new type manifold, used across the Popular Cylinder Spares cold water inlet control range.
Signs this part needs replacing
- Water discharging continuously or intermittently from the relief outlet or tundish
- Dripping or weeping from the manifold body or its connections
- System pressure failing to hold, with repeated pressure loss at the cylinder
- Scale build-up or corrosion visible around the manifold and relief port
- The relief valve failing to reseat after a pressure event
Before you order
- Confirm your cylinder model against the manufacturer's parts list
- Check that an 8 bar relief rating matches your installation's requirements
- Identify whether your cylinder uses internal expansion or has no internal air volume
- Verify whether your existing cold water inlet control group takes the new type manifold
