Important Service Tips for Maintaining Your Hydro-Jetter

Share This Post

High-pressure jetting units are an investment that must be maintained properly to achieve maximum longevity and success. Simple steps should be taken regularly to ensure the long-term profitability of your sewer jetter machine. Below we outline the various tasks that should be done before every use of your machine, at specific intervals of your usage, and at various times of the year.

Every Time – Prior to Operation

– Inspect your hose for any damage or rips.

– Check your water filter bowl & mesh filter to ensure it is clear of any debris. Make sure you check the inside of the mesh filter as that is where debris will collect.

– Make sure your sock filter is present and clean.

– Check oil levels for the pump (using pump site gauge) and engine (using dipstick)



Tier 3 fluid filter change – after the first 50 hours, then every 250 hours or once a year (whichever comes first)

Tier 4 fluid filter change – after the first 50 hours, then every 500 hours or once a year (whichever comes first)

Check your pump mounting and adjustment bolts – tighten them once a month to protect your belt from getting loose and shredding as a result



Check frames for any cracks.

Check brakes (when applicable) by hooking your trailer to a truck and verifying they are stopping appropriately.

If you have hydraulic brakes, check your hydraulic reservoir to ensure it is still full of liquid.

Check safety chains for any weak or worn areas.
