Grease Clearing Jetter Nozzles

Rotating nozzles are the right call for grease. They scour the full circumference of the pipe wall rather than just punching a hole through the blockage, which means you're actually removing buildup instead of pushing it downstream. Many rotating nozzles can carve out hardened grease whether your jetter runs cold water or hot. For most grease work in 1½"–8" lines, a controlled rotation-speed nozzle calibrated to your machine's GPM & PSI will outperform a standard penetrating or flushing nozzle every time.

Both are controlled-rotation nozzles, but built for different setups. The less expensive Grease-Hog nozzles run 4 rotating jets that can be calibrated for a wide range of machines and is the lower-maintenance option because it has no bearings; these create a “water-bearing” by  allowing about 15% of the GPM to “leak” around the rotating part. The Warthog WT, WS, WX, and WH models run 3 highly aggressive slow-rotating jets which have extreme cutting-action to carve though hardened grease. Further, the Warthog WT, WS, WX, & WH have a much more water-efficient sealed bearing system that requires regular viscous fluid service. The Grease-Hog is your everyday grease tool. The Warthog is the heavier-duty investment for operators who consistently face hardened-grease, and other tough blockages like tree-roots, etc..

Match your hose connection size to the nozzle model, then confirm your machine's GPM falls within that model's range. Running a nozzle sized for 12 GPM on a 8 GPM jetter will fail to build full pressure at the water-jets, which is where your cutting power lives. Every Grease-Hog from Jetters Northwest can be calibrated to your jetters GPM/PSI specs. If you're on a small electric-powered mini-jetter, choose the 1/8" Grease-Hog Nozzle for Electric Jetters” which is orificed for low-GPM operation. Shop Grease-Hog nozzles here.

A ball nozzle is shaped to make turns easier and can be used as a blunt-force head built for maximum thrust to punch through a soft grease blockage, especially on longer runs in 2"–4" lines. A rotating nozzle like the Grease-Hog is the better call when you want to scour buildup off the pipe wall, not just clear the centerline. Use the ball to break through, then follow with a rotating nozzle to clean the line properly. See the Grease Ball Nozzle here.

Yes, and it's common. A Warthog WT handles grease and roots in the same pass, which is why it's a go-to for lines where you're not sure what you're dealing with. The Bulldog nozzles are slightly less aggressive on roots but are faster at clearing grease than the Warthog types. “Turbine” type nozzles like the Reaper, Rotodrill, and Root Ranger series are more aggressive for clearing blockages but less effective at moving sludgy grease or clearing side-wall buildup. Match the nozzle to what you know is in the pipe, and how versatile you do or do not need the nozzle to be. See the full nozzle lineup here.
