Have you ever heard of SIAMESE PRESSURE WASHERS?  This post and video features a large commercial parking lot job.  This particular job was extremely dirty with tons of mud, dirt and debris and took longer than expected.  So on the second day, I was able to SIAMESE PRESSURE WASHERS, using two machines to create one flow.  So between the two machines, we were able to achieve 17 gallons per minute.  This reduced our rinsing time in half and can be done with two individual pressure washer machines.


Pressure washer machines are rated by gallons per minute.  So the higher gallons per minute you have, the more powerful the siamese flow will be.  In this siamese pressure washers example, I have an 8 gallon per minute machine and a 9 gallon per minute machine.  I was able to hook the two machines together into one output flow combining for 17 gallons per minute when rinsing.  The kit you need to execute this is available at my Doug Rucker Store.  I provide extensive detail on this product and how to hook it up.  Be sure and watch the entire video for all the details.  Two machines run together at one time into a T connector with check valves.


It is best to start the lower GPM machine first.  So in our case, we begin by starting the 8 GPM machine first.  Then we start the 9 GPM machine.  If both machines are identical then this is obviously not a consideration to worry with.  But just remember to start the lower GPM machine first.  One of the things the video demonstrates is how we were able to pick up the pace using our surface cleaner.  We then rinse with an open valve and I explain the reasons for this in the video as well.  If this helps you, consider attending one of my monthly training events in Houston. These events include on the job training as well as classroom instruction.  It’s also a great way to meet some new friends in the business.  Thank you for checking out this siamese pressure washers post.
