Managing water pressure is important
  • Minimum Pressure required is 290psi (20 Bar)

Not for use with Hot water, Max 105 Degrees F (40 C)

For Pressure washing sizing the Brushes 2 tips (#3.5) are the same as a #7 tip in your Pressure washer

We recommend the use of an inline pressure gauge to monitor pressure..

A Small Pressure Washer 2.5 GPM at 3000psi is all you need to run this water powered brush.

Do not run a larger pressure washer with this brush at it will damage it.

Connecting to a Extention Wand

When using an Extension Wand that has an M22 Male Tip on the  end. Then to attach the water poered brush be sure to order a Female to Female M22 Fitting to connect the brush to the extension wand 

Regulator and Gauge

Use a Pressure Gauge to undestand the pressure at the brush

Install the Gauge on the water connector on the brush

Test Run your your pressure washer and supply water to the brush from your running pressure washer the PSI should be between 290 psi and 725 psi.

One you have your system setup at the correct pressure ytou can remove and store the gauge for future testing

Alway test again after a pressure washer has been worked on or should a different pressre washer is put in place to power the brush


If your pressure Washer is running the brush at more that 725PSI then immediatly stop the water flow.

You can try a smaller pressure washer or install and adjust a  Pressure Regulator to set the pressure to the suggested 600 to 650 psi to run the brush. (Max 725psi)

Regulator and Guage not included
