WARTHOG (Stoneage Tools) Jetter Nozzles

Yes. StoneAge is the manufacturer, Warthog is their product line for sewer/drain cleaning. The name "Warthog" comes from StoneAge and it's become renowned in the industry as the first nozzle “tool” that could truly cut roots with water-jets alone – no chains or cables required. Jetters Northwest carries the full StoneAge Warthog line, keeps service parts in stock, and does repair/rebuild service work. For demos and tech talks, check out the Jetters Northwest YouTube channel.

The WT, WS, and WH “classic” models do the bulk of the heavy lifting with high-impact, slow-rotating water-jets; physical size and GPM capacity is the difference between them. The newer WX models (aka WTA) are designed for descaling and extra hose-pulling power, plus a brand new WX “Pusher” model is coming out soon. The WV is a smaller 1/4" nozzle that’s designed to spin at a faster “medium speed”, making it a premier grease and sludge clearing head. 

The compact WT-3/8 and WT-1/2 heads handle 3 to 8-inch lines, while the efficient WS-1/2 is built for 4 to 12-inch pipe, and the larger WH classic models are suited for 6 to 24-inch pipes. Match the nozzle to the pipe size, not the other way around. Check the individual product specs on our Warthog nozzle pages to confirm the right fit and GPM/PSI specs to match your jetters.

All Warthog nozzles can handle up to 5,000 PSI, but Running short on jetter GPM-flow is the most common mistake operators make because Warthog models/sizes are actually GPM-flow driven: The popular WT models are designed for jetters in the 5 to 16 GPM range, while the efficient WS-1/2 is built for 15 to 21 GPM jetters. The WX descaler requires from 9 to 21 GPM from the jetter. The small WV-1/4 grease-cutter heads run on 4 to 9 GPM, but you can feed them with a 10-20 GPM jetter as well. The larger WH-1/2 is built for clearing larger lines hence it requires 15 to 25 GPM (larger 3/4" WH models handle up to 50 GPM). Watch our Warthog WT in action on YouTube to see how it performs at real-world GPM and PSI.

Staying on top of lubrication is what keeps Warthog nozzles spinning at an efficient speed: The factory recommends refreshing the viscous lube fluid in WT, WS, WX, and WH models abround every 40 hours of use but we recommend twice that often if you use the nozzle heavily or have hard water. The nozzle’s high-pressure seal and seat should typically be replaced every 150 to 300 hours, but note that running hard water – or a lot of heavy silt / grit clearing jobs – will push you toward the shorter end of that range. The small WV models are sealless thus simply need a WD-40 type lube sprayed on and in them after each use. Read our full breakdown in the Feed the Warthog blog.

The “Lube Kit” includes the viscous lube fluid and a syringe tool to inject it. The “Service Kit” adds the high-PSI seal and wearable seat you'd swap out during routine maintenance. An overhaul kit goes deeper adding the main bearings and shaft-seals to fully rebuild the nozzle from the inside out. Lube kit for daily/weekly lubrication. Service kit for scheduled internal maintenance or when performance drops off. Overhaul kit if it's been a few seasons or the rotation is stalling or has seized up. Shop Warthog service kits and parts.

Viscous fluid is a very thick lubricant that lives inside the Warthog’s bearing housing. It does two important jobs: (1) it lubricates the internal bearings and seals, and (2) it keeps the Warthog’s  rotation-speed slow so the water-jets can have maximum impact and tearing/scouring action. When the lube breaks down or is fouled with water, the nozzle inefficiently spins too fast and wears out quickly, possibly seizing up. The WT and WS models use "Slow" fluid. The WX and WH models take "Fast" fluid. Shop viscous fluid here. (Note: WV models do not hold lube; they simply require a WD-40 type lube sprayed on and in them after each use)

The smaller models, specifically the WT, WV, WX, and WS models, are designed to navigate elbows and cleanouts in residential and light commercial laterals. Larger WH Warthog models are built for larger/longer lines, not tight bends. If you're regularly working through 90’s in smaller pipes, make sure you're running the right size model for the job.

The Warthog’s forward-jet can forward cut, but its slow-rotating rear-jets are the star of the show. The heavy rear jets rotating slowly rip through grease buildup and root-intrusion while scouring the pipe wall, leaving a truly cleared line. The thrust from the rear jets provide excellent hose-pulling power. Again, it can have front-cutting action, but it is slow going compared to new “coring nozzle” designs, and many operators used their Warthog with the forward-port plugged off to maximize the power and thrust of the rear-jets. For maximum forward attack into root obstructions and other blockages look at the Reaper nozzle – many contractors pair the Reaper with the Warthog for an efficient “one-two punch” to unstop the line and scour the pipe walls clean.

Yes: The Warthog’s slow-rotating design provides the platform for excellent jetting results, but its orifice-tip inserts are what create the sharp penetrating and tearing action of its water-jets. It’s good practice to replace the orifice-tips yearly, or even quarterly if your Warthog is in use every day. Why? Because high-velocity water gradually erodes tiny channels into the orifice-tips which cause its water-jets to fog and disperse, losing their sharpness and impact. Literally it’s like trying to cut with a dull knife, so regular replacement is key. Each orifice-tip has its bore-size engraved on its side – be sure to order exact replacements. Any change to the actual orifice size can significantly reduce the GPM or PSI power at the nozzle. Need help with this? Give our team a call today!
