Under Pressure Hydrant & Mains Isolation System
Using the Hydrant Wizard System, the flow of water in the Main is not affected.
A simple Golf Blade Saddle is fitted to the riser between the Hydrant and the Main, through which a small hole is drilled under pressure.
A Mini Hydro® Bag is inserted and inflated to create the isolation. Inflation is controlled by a pressurisation unit using the mains pressure through the Sniffer facility within the Hydro Bag.
When inflated, the hydrant can be replaced and then the Hydro bag can be removed leaving the blade saddle as a future access point when required.
