Simpson Dial-n-wash
So what is a Dial-N-Wash? Actually it is a very cool product by Simpson pressure washer. With this small little gadget, you can turn any ordinary pressure washer into a variable pressure washer. All you have to do is simply screw this onto the wand and now you’re set. You can adjust the pressure of your pressure washer right from the wand. Why is this so cool? Well now you can do your patio with a low pressure and your driveway with a high power setting. I have a Ryobi pressure washer which has been great to me. One thing I can’t stand is the higher pressure when I am trying to clean the pavers on my patio. I end up spraying out the sand and doing more harm than good. With this little gadget, I can dial down the pressure and go to town.
A user can adjust the pressure from 1000 psi to a max of 4500 psi, if your pressure washer goes that high. To use the Dial-N-Wash just turn the plastic ring either direction to get your correct setting, it is that easy. If you want to be able to adjust the pressure of your unit, this is a great investment.
What We Like:
Works with almost any pressure washer
Easy to put on
What We Don’t Like:
The unit is wider than the wand, so hopefully when it gets dropped it will hold up.
Specifications:
Adjust pressure from 1000 PSI to Max PSI with a simple twist

Most Helpful Critical Review   Not Recommended First time used, it leaked. Had to finish job without. Never had time to send it back.
 Dennis Does Not Recommend This Product Product Expert Dennis, I'm sorry the regulator leaked when you used it. It has a 30 day Factory Warranty from the folks at Simpson which has unfortunately expired- you would only have had to call Simpson to report the problem. You may still want to give them a call at 877-362-4271 to see if they have any advice for getting a better seal between your wand and the regulator.
We appreciate your business and apologize for any inconvenience. more Brand Rep Dennis, Hello my name is Zac and I am the Assistant Service Manager for the FNA Group who manufactures the Simpson line of gas pressure washers.

Product Defective
It always sprays water backwards... at me right from the beginning. Customer service connected me directly with Simpson. Simpson insisted I have to return it to the retailer I bought it from even though Pressure Washer Direct says I have to go to Simpson.
I'm replacing one that froze, so don't be a numbskull like me and leave it out in below freezing conditions. My old one was all around excellent so I know it's a good product. Just returning a defective one is problematic. Pressure Washer Direct has to communicate more effectively with Simpson in order to provide us with better service.

This Actually Works.
Now I can turn the pressure down and use the power washers on my motorcycle. It's nice to be able to control the pressure for lighter or more fragile things like window screens (those nylon ones especially).

Does Not Fit!
I had a Simpson water blaster 4200 on order and I ordered the dial and wash as well. Thinking that because my PW is a Simpson I thought the Simpson Dial-N-Wash would fit but no such luck. Blaaaahhhh.
Brian Does Not Recommend This Product Product Expert Brian, I apologize for the issues however, the Simpson you have is a professional unit and uses a 1/4" connection instead of an M22 connection on the spray gun. The Simpson unit you own has adjustable pressure at the pump and would not be the correct unit to pair with the Dial-N-Wash and would not be the correct fitting. moreBrand Rep Brian, Hello my name is Zac and I am the Assistant Service Manager for the FNA Group who manufactures the Simpson line of gas pressure washers.

Simpson 82235 Pressure Regulator
The Simpson 82235 pressure regulator did not work on my Karcher G3050OHC pressure washer. The Karcher has a Honda GC190 engine that uses a governor to increase engine speed when water is needed. The engine runs at a slower rpm when water is not needed and increases rpms when you pull the trigger to use the washer.
When using the washer with the Simpson pressure regulator attached, the washer works normal at full pressure, but when you reduce the regulator down for less pressure, the governor slows down the rpms and the water trickles out of the nozzle until the water is out of the hose and then it kicks in at full blast until the hose is filled and then the governor slows down the engine again with a trickle of water coming out.
I had hoped that this regulator would let me reduce the pressure from 3000 psi to 1500 psi for vehicle and RV washing but with the Honda engine set up this way, you can only wash with the full 3000 psi.

Dont Install It Where The Manufacturer Says To
If you install it in the middle of your wand, it will break in half from the use and will also come loose. Mine broke in half the first time I used it. If you need to have adjustable pressure, get a pressure washer that has a regulator built in it.

Works Like A Charm
I bought this when purchasing a new single-flow Simpson power washer. It complements the nozzles perfectly, reducing the odds of etching soft wood or painted finishes.
A great compromise to the option of paying $100+ for a variable pressure model.
