Hydrant Wizard

altimg
The Hydrant Wizard has been designed to enable defective fire hydrants to be exchanged – ‘underpressure’.

Previous practices for exchanging a hydrant involved shutting down the main either by closing valves or using traditional line-stopping techniques. However, valves could often be some distance away so that supplies to customers would be interrupted.

In addition, both these methods of shutting down and restoring supply could disturb sediment in the main leading to complaints regarding water quality.

Hydrant Wizard – Key Features & benefits…

• During development of Aquastop, a need for stopping off of hydrants was also identified. This also required developing a stopper bag jointly with Sarco Stopper resulting in the Sarco Mini Hydro® Bag
• Only the Hydrant is isolated; the flow in the main is not interrupted
• Supply and water quality are unaffected and sediment in the main is not disturbed
• Excavation is restricted to the area around the hydrant minimising the cost of labour and materials
• The small diameter access hole does not compromise the integrity of the pipe The only consumables are the Sarco Mini Hydro® Bag and the Mini Golf Saddle which remains on the hydrant leg
• Easy to transport in small vehicle
• Prep tool enables easy access for the Sarco Mini Hydro® Bag regardless of tuberculation
• The equipment is compact and lightweight and suitable for confined areas
• Sarco Mini Hydro® Bags are inflated utilising the water pressure from the main. No additional power source is required for operation of the unit. The danger of over or under inflating the bags is eliminated
• Equipment is easily sterilised before each use and is made from non-corroding materials
