High-pressure jetters are ideal for cleaning drainlines of soft obstructions like sediment and grease, and for general flushing. With regular care and maintenance, MyTana jetters deliver superior, reliable performance, helping professional sewer and drain cleaning contractors get the job done quickly.

Here we discuss some troubleshooting you can do to solve some of the pressure issues that can afflict any jetter from time to time.

  • Low pressure
  • Loss of pressure
  • Pressure spikes

Pressure issues can be caused by a few different things, most of which have simple fixes. These three steps are a good place to start your diagnosis:

1. Clear the nozzle. The holes in a nozzle are very small and it doesn't take much to clog them. Once clogged, spray pressure and volume will suffer. To clean a nozzle, first power down your system and clear all pressure from the line. Then unthread the nozzle and ream out its orifices using the cleaning tool supplied with your MyTana jetter. Be aware of the angles of the jet openings. Once the orifices are clear, securely reattach (hand-tighten) the nozzle and power up the system to see if that solved the problem.

2. Test the water supply. Jetters require a certain flow rate for supply water in order to function properly. Check your owner's manual to find the gallons-per-minute capacity for your jetter model. To test the water supply, perform a bucket test. Using the water source (generally a spigot or garden hose), fill a 5-gallon bucket for one minute. If the number of gallons in the bucket after one minute falls short of the required gpm rating, then your jetter is not receiving enough water from the source, which will adversely affect its spray pressure.

3. Test the water supply through the jetter. If your nozzle is clear and the supply is sufficient, then test the flow through the jetter hose. Perform the bucket test again using the jetter hose without a nozzle attached. If the jetter is still producing the appropriate gpm, other issues could be the problem.

A leaking jumper hose or the ball valve that connects the jumper hose to the high-pressure hose could be the culprit. Inspect those.

Know the size and length of hose that is optimal for the jetter to perform correctly. The longer the hose, the lower the pressure at the nozzle. Be sure to follow manufacturer’s recommendations for hoses.

Finally, the issue could be in the pump itself. New noises or milky/cloudy oil in the pump could indicate a cracked ceramic plunger or bad seals. Other problems in the pump can cause drops in pressure and performance as well.
