Pressure Wash Downstream

What is the difference between plug in/socket out versus plug out/socket in? While I have several videos on Pressure Wash Down Stream basics, I did receive an email with questions about pressure washer configurations. Some of the products on the store website provide a configuration option for you to choose from. You can select either plug in/socket out or plug out/socket in. This can be somewhat confusing, especially if you are new to the pressure washing service business. So this Pressure Wash Downstream video will help clarify some things and answers questions you may have.

FLOW DIRECTION

This entire issue boils down to the direction that the water flows from your pressure washer machine. On the water outlet from the machine, you will have either a socket fitting or a plug flitting. Sometimes the socket is also called a coupler. The way all of my machines are set up is “plug out.” But most machines arrive from manufacturers with a “socket out” configuration. We provide custom builds and this means you can choose your own personal preference for this option. At the 2:50 time stamp, I provide an example of one of our store products on the website with this option. At 4:30, you’ll see a very important but small arrow which indicates the flow direction of the water. So understanding pressure wash downstream configuration really boils down to the direction the water flows.

PRESSURE WASH GUN

Then I also explain how this configuration option applies to a pressure washing gun. At this point, I explain once again that his is all simply a matter of personal preference. One of the main reasons I prefer the “plug out” option is I get as much better flow and spray pattern. That is the case when I use a ball valve to downstream or rinse. Another way to explain this is that whatever your water is coming “out” of, that is your outlet fitting. Please don’t hesitate to put any questions you may have about this in the comments section. And be sure and take advantage of all our training opportunities coming up in the near future.

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.
