Wizard, Deployed Bag & Hydrant
In the Hydrant Mini Line Stop System the flow of water in the Main is not affected. A simple Golf Blade Saddle is fitted to the 'leg' between the Hydrant and the Main, through which a small hole is drilled under pressure. A Hydra™ stopping bag is inserted and inflated. Inflation is controlled by a pressurisation unit using the line pressure through the Sniffer Hydra™ Bag Service Spine in the entry hole. When inflated the defective Hydrant can be replaced and Hydra™ Bag removed.

Key Benefits:

• Only the Hydrant is isolated
• Main flow is not affected
• No independent power source required
• Supplies to customers unaffected
• No discolouration
• Suits restricted excavation
• Compact & light weight

• Hydrant conversion option for future Zero Dig Mains Service & Repair points.
