Root Ranger Nozzle
The Root Ranger Nozzle is possibly the best root cutting nozzle available today for thoroughly cleaning roots, grease and debris from a drain. It only has one moving part and can be cleaned on site without tools in 1 minute. It features an optional offset front jet for forward penetration. (This will reduce the forward thrust by 15%). It is sold worldwide to plumbers who need their drains cleaned properly, the first time. It is an extremely reliable nozzle.
Caution, cheap copies are now in the market. The original Root Ranger is made by Mustang Nozzles Australia from High Strength Stainless Steel so it will last for many years.
