Simpson MSH3125 Review

Now I’m starting my technical analysis of the Simpson MSH3125. I’ve read a few other assessments on this model, and it appears that most people are pleased with it.

Performance: Great for small and big jobs

The power of this tool is what makes it unique. The water pressure is 3,200 PSI, and the water flow is 2.5 GPM (gallons per minute). 

This tool can clean most surfaces. For example, we used it as a pressure washer for our house, and we could remove the mold on some of the siding panels easily. 

Note: If you want more power than this unit, you should look into gas-powered models.

Durability: Strong and sturdy

Getting the GPM and PSI is one thing, but how well-built is it? Well, this model has a steel frame that makes it durable. It also features a high-quality axial pump for long-lasting performance. 

The nozzles are brass so they won’t rust easily from all those chemicals you’ll be using. In addition, they can adjust the flow and pressure of the water with just a push of a button.

Fuel Life: Sufficient for most tasks

The Honda GC190 engine powers the MSH3125. The MSH3125 has a 0.5-gallon tank, which is not the biggest, but it’s enough to do most jobs. We used it to pressure wash our house, and it lasted for about two hours.

Design: Improvement Needed!

The MSH3125 is a powerful power washer that can clean even the most filthy messes. However, this device is a mixed bag, with some fantastic features and others that may be annoying.

Price: A fair price for heavy-duty performance

Although you can find some cheaper models, this one is not that expensive compared to other similar power washers on the market. Currently, it’s selling at around $400.

Maintenance: Easy and simple

Like any other power washer, you’ll need to change the oil after a while. But make sure you are using Simpson’s formula for this machine because it is designed for Simpson products.

Noise Level: Quiet for a gas-powered model

The MSH3125 is not that loud, but it’s noisier than your average power washer. The Honda engines are known for their relatively quiet operation, and Simpson uses them in their products. 

We took measurements from both close to the machine and 25 feet away. The pressure washer’s operator will be exposed to an ear-splitting 93.2-decibel level. The sound level drops to 80.1 decibels at a distance of 25 feet, which is still quite loud.

Warranty

  • Five-year limited frame warranty
  • 90-day limited accessory warranty
  • 2 Year limited HONDA consumer engine, 1-year limited pump, 5-year limited frame, and 90-day accessory
  • One-year limited pump warranty

Customer Support: Should be better

When it comes to customer service, Simpson sucks. Do not expect a quick solution to clashes and difficulties with most of its technical support outsourced. To get the missing components back, you must wait two weeks.

 You might connect with someone who doesn’t understand what you’re telling them but isn’t particularly interested in assisting.

Experts’ View

The SIMPSON MegaShot MSH3125 Pressure Washer is a powerful machine that can handle almost any cleaning task. However, a few poor design choices may be annoying.

SIMPSON Cleaning MSH3125 Assembly

The machine is a durable power washer that will last for years. In addition, it comes partially assembled, so you don’t have to worry about putting it together. 

Just follow these steps instead:

Step 1: Attach the handle until it snaps into place

Step 2: Add oil before firing it up. Although SIMPSON provides the oil with the power washer, we provided the fuel. The oil is kept in a soft bag that can be damaged if mismanaged. 

Note: Overall, assembling took us around 15 minutes.

How to Run SIMPSON Cleaning MSH3125

Now that your machine is set up, it’s time to start cleaning! Here’s a quick guide on how to use the pressure washer:

Step 1: Fill the gas tank with unleaded gasoline.

Step 2: Snap in the high-pressure hose.

Step 3: Connect the garden hose to a water source.

Step 4: Open the water source.

Step 5: Pump the handle a few times to prime the pump.

Step 6: Squeeze the trigger on the gun to release the pressure.

Step 7: Set the choke lever to the “run” position.

Step 8 Pull the cord to start the engine.

Step 9: When finished, release the pressure from the hose by squeezing the trigger on the gun.

Step 10: Set the choke lever to the “off” position.

Step 11: Turn off the water source.

Step 12: Unplug the garden hose from the pressure washer.
