Fitted with two rear facing fan jets the small plough jet nozzle is great for de-silting drains and sewers. The heavy forged brass construction keeps the jet firmly planted in the base of the pipe where the silt deposits collect and blasts them back towards the manhole. 1/4"-nozzles need to be assembled under 45° to achieve best cleaning results. Select nozzle size according to pressure and flow rate of the machine.
