Only the hydrant is isolated; the flow in the main is not interrupted.
The small diameter access hole does not compromise the integrity of the pipe. The only consumable is a small plate valve which remains on the hydrant leg.
No independent power source is required.
Excavation is restricted to the area around the hydrant minimising the cost of labour and materials.
Supplies to customers and water quality are unaffected throughout the operation. Sediment in the main is not disturbed and flow is uninterrupted.
The equipment is compact and lightweight and can be used in confined areas.
