Maintaining and Servicing Sewer Jetters

Consistent sewer jetter maintenance is key for optimal performance, reliability, and longevity. While our industrial sewer jetters are built to last, even the strongest machines require regular upkeep to function at their best. By performing consistent maintenance, you can extend the life of your sewer jetter, minimize costly downtime, and ensure reliable performance. In this guide, we take you through the best routine maintenance practices as well as how to perform minor repairs and troubleshoot any issues.

Best Routine Maintenance Practices

Whether you operate a cold-water jetter or a hot-water jetter, routine maintenance should be performed year-round to keep your model in top shape. Follow these steps for the best routine maintenance practices.

Daily

• Inspect hoses for wear or damage
• Check the nozzle connection for leaks, loosening, or cracking
• Clean the nozzle after each use
• Verify the oil level for the pumps, gearbox drive, and engine
• Drain excess water from the tank

Weekly

• Lubricate moving parts, such as the hose reel and pump components
• Inspect and tighten any bolts or connections
• Clean and examine filters for debris or blockages

Monthly

• Test the pressure gauge for accuracy
• Check belts for tension or signs of wear (if operating a belt drive machine)
• Inspect the fuel system for leaks or debris in filters and replace as necessary

Seasonal

• Perform a comprehensive inspection of all components
• Replace any hoses, nozzles, or seals if necessary
• Service the engine and pump semi-annually
• Flush the system to remove buildup

Potential Sewer Jetter Maintenance Repairs and Solutions

With consistent routine maintenance, the risk of damage to your sewer jetter becomes significantly smaller. However, occasional damage can happen to even the most well-cared-for machines. These simple solutions to common maintenance repairs can help save you downtime and protect your equipment.

Clogged or Damaged Nozzles

Symptoms of a clogged or damaged nozzle include reduced or extreme pressure, uneven spray, or a weak stream. You can remedy this by cleaning the nozzle with the appropriate tools to clear any debris that may have gathered in the orifices. If the issue persists after cleaning, the nozzle may need to be replaced.

Leaking Hoses or Connections

If you observe visible water leaks or reduced system performance, there may be faulty or leaky hoses and hose connections. Be sure to tighten all connections; if the leaking continues, this may be a sign of damaged hoses, which must be replaced to resume operation.

Pump Malfunctions

A drop in pressure or unusual noises may be an indicator of pump malfunctions. To resolve any pump issues, you can inspect all seals, valves, plungers, connecting rods, and the crankshaft. Check for air in the system or replace any damaged parts. These repairs will help restore your pump to optimal performance.

Engine Trouble

Your sewer jetter may be experiencing engine trouble or failure if it exhibits excessive difficulty starting or inconsistent performance. Do not attempt to operate a machine with a faulty engine. Instead, check the oil level, change the filter if necessary, check the fuel quality, clean the carburetor, and replace the spark plugs to bring your engine back to life.

Frozen Components

Frozen components are evident with a blocked water flow or cracked parts. Avoid this by using antifreeze during cold weather months immediately after operation and before storage. Be sure to completely and safely thaw all components before attempting to start and operate your drain jetter. Any leaks are signs that the fittings or hose have been compromised and should be replaced prior to using your jetter.

Troubleshooting Tips and Tricks

If you’re dealing with additional issues or faults in your jetter, these practical troubleshooting tips can help repair your equipment. Use these simple checks and quick fixes to resolve issues without costly repairs.

Low Pressure

Low water pressure in your sewer jetter may be the direct result of obstructions in your nozzle or hose. Check for any blockages and remove any buildup. Additionally, inspect the pump for worn seals or valves and replace if needed. Check the inlet water connections and filters for obstructions in water flow.

Inconsistent Spray Patterns

For inconsistent spray patterns, ensure the nozzle is properly seated and free of debris. Clean the nozzle if necessary. In addition, check the hose and fittings for bends, as they can cause water blockage and diminish pressure.

Failure to Start

If your sewer jetter won’t start, make sure the key switch is on, verify the fuel supply and engine oil levels, and ensure the fuel valve is in the “on” position. If your machine has a water tank, it will also have a water level switch—if no water is present or there is a low level of water, the engine will not start. Fill the tank and try again. Tighten any connections if necessary.

Unusual Noises

If your machine is emitting unusual noises or sounds, thoroughly inspect the unit for loose or leaking components or debris in the pump valves. Check the quality of the pump oil and engine oil—it should be a clear brown color. If the oil appears milky or metallic, change it immediately. Worn bearings, crankshafts, and connecting rods in the pump and engine can cause unusual noises and may lead to catastrophic failure. Call us at 800-641-5011 and let us assist you.

Preventative Sewer Jetter Maintenance Tips for Prolonged Operation and Lifespan

Performing preventative maintenance is one of the most important components to keeping your sewer jetter in top condition. Regular checks and simple care routines can help you avoid costly repairs and reduce downtime to keep your operations up and running. Follow these tips to prolong the lifespan of your sewer jetter:

• Store your equipment in a clean, dry, and temperate location.
• Use high-quality fuel and oil (Ethanol is not recommended!).
• Keep detailed maintenance records to track service intervals.
• Train all operators to handle equipment properly and recognize early signs of wear or damage.

No matter your applications or industry, preventative maintenance is key for extended operations.
