SEWERQUIP jetters are renowned for being powerful, reliable and simple to use. But if your sewer jetter won’t start, loses power or is noisy, here are some quick tips to get it back in action. Of course, our experts are always here to help so feel free to give us a call if you need a hand.
Symptom: My sewer jetter won’t start!
It should go without saying, but an empty fuel tank is surprisingly the most common problem we see! Other simple things to check in this scenario are:
- Fuel valve: Check that the fuel valve is turned on and/or not blocked
- Water level: Check the water level is not low and if so fill the tank up
- Electrical damage: Check the engine to see if any leads, plugs or wires are loose, cracked or hanging off
Symptom: The pump is noisy or sucking air
If you notice more noise than usual or an air sucking sound, there are a few common causes:
- Air in the line: Check that the water line and connection points are sealed to avoid air entering the suction – clean, tighten or replace lines if necessary
- Low oil: Add or replace engine oil regularly to ensure smooth and lubricated operation
Symptom: Erratic water pressure or low flow
If water flow and flushing power seem lower than normal, it can often be caused by the nozzle head being blocked or buried in a blockage, bend or trap. Here are a few simple things you can do to get it cranking again:
- Pull the hose backwards and then release it again to help it penetrate a particularly tough blockage – sometimes this can be done a few times to break up the debris
- Twisting the high pressure hose with your hands can help it work itself around bends and traps
- Different nozzles can be used for different applications – our range of jetter nozzles includes chisel points for penetrating heavy blockages, micro nozzles for very tight bends and rotating nozzles to cut through roots
- Sometimes the jetting nozzles themselves can become worn or blocked over time, so cleaning them out with a tip cleaner or replacing nozzles can help
Symptom: Oil leaks or water dripping
When operating correctly, your jetter should not be leaking or dripping oil or water during use or in storage. This issue is typically caused by worn seals or piston packing, which can easily be replaced.
- If water is leaking from any of the fittings tighten them if they are screwed fittings and if they are quick connector style fittings check that the o-ring is present and not worn in side the quick coupling.
- If oil is dripping this can be caused by operating the jetter on uneven ground levels, such as a steep street or driveway. There are breather caps in the pump and gearbox, so if the level is too far out when in operation, the oil can leak from these caps – wipe clean and even out levels
- If oil continues to drip it could be the seals contact SEWERQUIP or a mechanic to resolve this
Symptom: Engine keeps cutting out or runs poorly
If the engine starts but then cuts out or runs roughly, here are a few things to look at:
- Make sure the engine is sitting on a level surface, because if it operates on too much of an angle it may impact the oil levels and flow and disrupt the engine
- Check that the spark plugs are clean and firing as dirt or excess soot can significantly impact the running of the engine and reduce water pressure
- Check that the inlet filter is not clogged and blocking the flow – clean or replace if necessary
- Make sure there is enough engine oil and add or change if needed
- Dirty fuel can also affect the engine, so always ensure your fuel comes from a clean fuel can or straight from a bowzer
- A faulty low water shut off switch can also cause intermittent engine cut off – check that the wires are connected and not exposed or loose
- Make sure your battery leads are firmly connected
Symptom: Jetter freezes up in cold climates
Occasionally in cold areas, especially if the machine is exposed overnight, you may experience the pump, valves, hoses and/or fittings icing up and preventing water flow, meaning your sewer jetter won’t start. This may cause pressure build up and can cause injury if the pressure is released and ice shards are discharged. To release the pressure and restart water flow in cold climates:
- Turn off the jetter and ball valves
- Place the hose on the ground weighted down with no nozzle
- Ensure the hose is not aimed towards any person, animal or machinery
- Then pour warm water over the pump, hoses, valves and fittings until the pressure releases
Always remember safety first
Please always be aware that high pressure water jetting can be extremely dangerous and may cause death or serious injury if it is not properly controlled by fully trained personnel. Ensure that all the pre-operational checks have been completed and that any necessary safety actions have been taken as outlined in the user manual that comes with each product. If you have any concerns or have lost the product manual, contact us for another copy.

Want up to 30% more power from your existing jetter?
Watch this demo of our new 3FLOW Nozzles!
Our comparative testing shows that a 3FLOW water jetting nozzle can be up to 30% more efficient than an equivalent standard nozzle, so you get more flushing power from your current jetter, with the exact same pump and water pressure. By switching to 3FLOW Nozzles – featuring computer generated flow direction optimisation – you use less water and less fuel, while reducing wear and tear on your machine.
