PRESSURE WASHER CHECK VALVE

PRESSURE WASHER CHECK VALVE

The main purpose of this post and video is to provide instruction for pressure washer check valve repairs.  Many pressure washing professionals are installing a check valve into a downstream injector.  This provides a stronger mix but also depends on variables like strength of bleach and gallon per minute machine you’re using.  Hose length is another variable that affects mix ratios.  Another benefit is that a check valve will help the downstream injector last longer.

REPAIR KIT

The spring and valve seat will occasionally wear out and go bad.  This is the result of bleach and other chemicals in the mix, as well as grit and debris that invade the lines.  But there is a very simple solution for this issue.  There is a check valve repair kit which will come in very handy for this problem.  In this video, we provide step by step instructions on how to use this kit to repair a pressure washer check valve.

PRESSURE WASHER CHECK VALVE REPAIR INSTRUCTIONS

The check valve repair kit comes with an o-ring and a spring.  Our service technician, Edwin, shows precisely which tools you will need.  After disassembling, we see the problem spot as rust and corrosion is obvious.  There is a seal, a shuttle, and a spring.  They are fairly symmetric and we give detailed visual instructions on reinstalling with the new parts from the repair kit.  Re-taping the threads upon reassembly is also very important to remember.

HIGH PERFORMANCE LUBRICANTS

We use HIGH PERFORMANCE LUBRICANTS oil brand for all of our machines and vehicles.  The penetrating spray is especially helpful for cleaning any corrosion and repelling water.  Another great source of information you may find helpful is this Downstream Injector Check Valve post with video.  We hope this helps your pressure washing business!
