Connect the soap dispenser to your pressure washer using a hose. Ensure all connections are securely fastened and the soap dispenser is firmly in place. You can start jetting once you’ve connected all the necessary components. Press the trigger on your pressure washer wand to begin jetting at a low speed. When cleaning out blockages or deep clogs, increase the pressure gradually as needed.

Step 5: Connect the Pressure Gauge

Connect a pressure gauge to your system to ensure that you’re operating at the correct pressure. This will allow you to monitor and adjust the pressure as needed to avoid damaging the sewer lines or over-pressurizing the system. When you’re done jetting, be sure to clean up any mess that was created. Disconnect the hose and nozzle from the pressure washer wand and drain any water residue.

Step 6: Dispose of Waste Properly

Finally, make sure to properly dispose of all waste material that may have been collected during the sewer jetting process. This includes any mud, debris, or other contaminants removed from the sewer lines. It is important to dispose of these materials in an appropriate container and follow environmental regulations. 

Follow these steps to convert your pressure washer into a sewer jetter and get back to quickly clearing clogs and blockages in no time. With the right equipment, you can make your pressure washer even more powerful and do the job quickly and efficiently.

It is important to use biodegradable cleaning solutions when flushing a sewer jetter, as these will be less damaging to the environment than chemical solutions.

Additionally, when draining water from a sewer jetter, it is important to make sure that all solids and debris are removed first to reduce the risk of environmental contamination.

Researching local regulations before using a sewer jetter is also recommended, as some areas may have restrictions or bans on certain types of sewer jetter use. Finally, if possible, it is recommended to avoid using a sewer jetter in sensitive ecosystems such as wetlands and rivers.

What is the Best Way to Clean or Maintain the Drainage Pipes After Using a Sewer Jetter? 

After using a sewer jetter to clean your drainage pipes, it’s important that you maintain them properly for optimal performance. The first step is to flush the pipes with clean water to remove any debris or residue left behind by the jetter.

If you don’t flush the pipes, the debris and residue will build up over time and cause clogs in your pipes. Once the pipes have been flushed, you can use a drain cleaner solution to help dissolve any remaining debris and sanitize the pipes.

You should also ensure that all your drainage pipes are properly sealed and free of cracks or leaks. A sewer jetter could cause water to leak if there is an existing crack or hole in your pipe. If you find any cracks in your pipes, it’s best to repair them immediately. Lastly, you should conduct periodic maintenance checks on the sewer jetter system itself.
