Nozzles Questions and Answers

What do I need to specify to order a Warthog correctly jetted for my application?

A: Each order requires; the operating pressure at your jetting pump, maximum flow capability, hose ID, and hose length. With this information we can run our jetting program that assures your Warthog will deliver the most power possible.

How long can I expect the Warthog to last?

A: Service life is indefinite, as all parts are readily available, and the tool comes with detailed rebuild instructions. The model WT-3/8 is an exception, since the most expensive machined part is what wears in this design. As a result it’s sometimes a better idea to replace a badly worn WT-3/8 with a new one, than to rebuild it.

How big a root can the Warthog cut?

A: Tests indicate that roots up to 3/16 in. thick can be cut at normal jetting pressures, 2000 to 4000 psi. It is possible to cut bigger roots if the nozzle is positioned perfectly and allowed time to cut away at the root. TV inspection equipment is often used for this purpose.

How long a hose can be pulled by the Warthog?

A: That depends on the pump power available, but adequate pulling force is usually developed to pull 500 to 800 feet of hose. Additional pulling force can be attained by plugging the forward jet. Longer hose runs are not recommended because hose pressure loss becomes so great that jetting power is seriously diminished.

What is the biggest diameter line that can be cleaned with the Warthog?

A: Since most debris collects in the bottom of the line, there is no limit to line size. However, if the deposits to be cleaned are distributed all around the line from top to bottom, then limits do exist.

How big a jetting pump is necessary to operate a Warthog?

A: The smallest Warthog WT-3/8 requires at least 4.6 gpm at 2,000 psi to rotate reliably. Other models are supplied for greater flows.

Is it necessary to soak the Warthog in oil between uses?

A: No, the bearings are sealed in a chamber full of lubricant. It will prolong seal life if the tool is drained and water blown out with air before storing.

Will the Warthog remove concrete from drains?

A: Only if you are lucky! Fortunately concrete spilled into drains often mixes with water, sand, and debris which causes its strength to be dramatically reduced. In such cases, it is possible to clean with typical sewer jetting pressures. But if it is not diluted, or if it is allowed to set, then it might require pressures above 10,000 psi to remove – regardless of what jetting nozzle is used.

Will the Warthog remove tuberculation and mineral scale?

A: Yes it often does, but effectiveness depends on pump power and the exact nature of the deposits. Hard mineral deposits sometimes require jetting pressure as high as 10,000 psi. Perpendicular ports can be used on the Warthog head to maximize scale cleaning performance. Contact StoneAge, for optional jetting designs.

I’ve been disappointed with spinning nozzles before. Why is the Warthog better?

A: The Warthog uses a patented control mechanism to limit rotation speed so that jet quality is maintained and dwell time of the jet on the deposit is increased. Also, fewer but bigger, high quality jets are used. The result is much more powerful jet impact on the deposits to be removed.

Will the Warthog damage vitrified clay lines or PVC lines?

A: At normal sewer jetting pressure and flow, it will not damage vitrified clay that was built to modern quality standards. If the nozzle is kept rotating and moving, then normal sewer jetting pressures and flows will not damage PVC lines. If not rotating, or if allowed to sit in one spot, it is possible to damage, even perforate PVC.
