Choosing the Right Nozzle
The relationship between pressure drop (PSI) through a sewer jetter nozzle, flow (GPM) and orifice size (Nozzle #) can be expressed as: However, if you rely on this formula alone when designing a sewer jetter you can overload your pressure washer or pump. That’s because the formula doesn’t account for pressure buildup in the jetting [...]
Choosing the Right Jetter Hose
When building a sewer jetter there's a tradeoff between using a lightweight, small-diameter hose that's flexible enough to move easily through clogged drains, and a larger hose that's costlier, less flexible, and can be more difficult to feed through a sewer line. While small-diameter jetter hoses have their advantages, there's a big [...]
Pressure Drop In a Jetter Hose
In our article about choosing the right sewer jetter hose, we talked about how the diameter of your jetter hose can have a big impact on the effort needed to clean a drain. Larger diameter hoses are less flexible and move less easily through dirty sewer pipes. Too small a diameter can overload your pressure washer. How do you choose the right [...]
