Q: hello bill, i am in the plumbing business and noticed that most sewer jetter have the same psi and rpm as the high end pressure washers, aside from the hoses what is the difference? by John from California on January 02, 2012
A: The difference is in the nozzle.
A pipe cleaning nozzle vents backwards, allowing the water pressure to move it through the pipe. As the hose is pulled back, the water breaks up clogs and debris.
Water pressure, nozzle size, and hose size need to work together based on the size and length of the pipe to be cleaned.
Q: The AR 620 has a pressure adjustment. When the PSI is reduced does it increase the GPM, or does it stay the same? by Anonymous on October 25, 2011
A: As you reduce the psi, the gpm will slightly increase. However, the highest gpm rating you can get from the pump on this model is 2.1 gpm's. The rating of 1900 psi and 2.1 gpm is the max rating of this pressure washer, not the operating ratings. This is how all pressure washers are listed and adverstised as. by Bill, Product Expert
Q: Hello Bill my name is Richard, I've been looking for a pressure washer that can pull water from a tank of water (self priming) for a mobile detail business so it has to be electric because of the noise. Looking for something under 500 dollar at 1800 psi or up. Any toughts? Thank you for your time. by Richard from South Carolina on April 14, 2011
A: Only Karcher, Kranzle, and DirtKiller brand pressure washers have self priming pumps with this capability. Any model from these brands can pull water from a tank. In your price range, you will more than likely have to purchase a Karcher model. Kranzle offers the best quality pressure washers made but the lowest costing model is around $670.00. by Bill, Product Expert

Bill's Recommendation
This unit from AR also works harder than it's small size might indicate. Its triplex pump (usually found on larger units) uses ceramic plungers so it can run cooler and last longer.
We also like the bells and whistles- it comes with a bonus turbo nozzle for cleaning grit and grime off tough surfaces, a siphon tube so you can apply detergent from a bottle or bucket, and a quick connect for the hose to save your knuckles.

Trying something new.
Have always used the Cam Spray 1500A but decided to try something new. The pressure isn't as high as AR rated, but so far it hasn't blown a breaker and the nozzle gun work much nicer.
For those afraid of trying something new but are looking to save some $. Its nicer in some ways to help make up for not having quite as good of pressure as the Spray Cam 1500A. The pressure difference is probably between 5 to 8%.
