Q: Is there any real difference between these two model numbers for Simpson pressure washers "MSH3125-S and MS31025HT-S ?" I have researched both and both are the same price at many locations. The biggest difference besides some subtle word play about having a commercial GC190 engine is the color. Lastly which one would i receive if i ordered from your website? Any help with this would be greatly appreciated.
by Ryan from Kansas on August 06, 2016

A: First of all, the Honda GC engine is their consumer grade unit- their commercial grade engines all start with GX. Both of these units come with the consumer grade engine.

Feature for feature they appear to be a match. It looks like the "T" version could be a special edition they made for a warehouse store. The handle angles look a little different- but that could also be the way the photos were taken.

We work very hard to make sure what you see online is exactly what you get in the box delivered to your door- so if you order from us, you will get the black engine cover.

The other thing to remember is that you won't pay shipping or sales tax when you order from us. (Sales tax is charged on Illinois orders, since our warehouse is in Chicago.)

Thank you for your interest in Pressure Washers Direct!

Q: What's the dimensions of the box it comes in? Thanks
by Dave from New York on July 10, 2016

A: The shipping box is 33 inches long by 21 inches wide by 19 inches high.

Q: Mike,
2 questions:
Wood piers and plastic decks- is this to much pressure for treated wood and plastic decks?

The pressure washer comes with 25' of hose.
if i want to add another 25 or 50' to existing hose do
i need an adapter. If so what is the part number and price.

by Bill Holmes from Illinois on July 04, 2016

A: It would work well for either application and have included the hose information for the extension.

Q: Does it have a safety or control release valve to protect the pump?
by Randall Beem from Missouri on June 30, 2016

A: The pump does have a thermal relief valve which will pop if the water inside the pump gets too hot. It is not good for this to have to pump as it meant the seals could have already been prematurely worn from heat.
by Brian, Product Expert
Q: Hi Mike,

I'm looking for pressure washer with 3000 psi, because that's what was recommended to me in order to use a telescopic 25'+ wand with it effectively. Thing is, I'd like to get a unit that has a 3/4" hose. I like the stats on the Simpson MegaShot 3100 PSI (Gas-Cold Water) Pressure Washer With Honda Engine, as well as the price, but it comes with a 1/4" pressure hose.

Can I buy a 50' or even a 100' 3/4" hose and use it with this machine instead? In other words, will it still connect to this machine and gun or no? Do you have a suggested unit that's better, at a similar price? One you recommend? I will be using this annually on my house, deck, fence and drive with sidewalk. Residential, but want it to last, if that helps.

Thanks,
Gordon

by Gordon from Georgia on July 19, 2015

A: Yes, you could purchase a 100 FT hose to use with the unit. However, those hoses are quick connect and would require you purchasing 2 adapters to attach it. You would need adapter model D10037 and D10088. I have attached links for you to view both adapters and the 100FT hose I would recommend.

Q: This pressure washer works fantastic. The only problem is that it shakes so much that the spray tips come out of the holders. When using on concrete the machine will just spin around. What can I do to stop the movement?
by George from Iowa on June 14, 2015

A: Unfortunately, there is no way to stop the vibration of the unit while in operation. However, you will have to make sure you are constantly spraying water. This should cause the unit to not vibrate as much and is not damaging the pump. when the unit is left in idle for to long, the water will heat up and damage the pump seals.
by Brian, Product Expert
Q: how many cc's is the motor?
by Bob from New Jersey on June 07, 2015

A: This unit uses a Honda GC190 which is 190CC's
by Brian, Product Expert
Q: Does this power washer come with the oil for the pump and engine when I make my order?
by Chris Janz from Louisiana on May 04, 2015

A: The pump is sealed (no maintenance of oil) and will be shipped with oil in it. This will also come with a quart of oil shipped with it for the engine. There may be some residual oil in the engine from when it is tested at the factory so we recommend to check the level and add as needed (be sure not to overfill).
by Brian, Product Expert
Q: Can you adjust the pressure?
by George from Massachusetts on April 08, 2015

A: This unit does not have adjustable pressure at the pump, however, it is just a matter of choosing the right colored spray tip for your application.

Q: Can this or any pw work with gravity fed water? I would hook it up to a 45gallon water tank not a faucet under pressure.

Thanks

by Rick from Arizona on February 02, 2015

A: No, this unit needs to be attached to a water source with a Min of 20 PSI and 3GPM. The only units that can be gravity fed are the belt drive units.
by Brian, Product Expert
Q: On the Simpson Megashot 3100- if i order it can i get 50 feet of hose with it?
by Peter from Connecticut on July 22, 2014

A: You can order an extension with it to make your hose 50 feet total. This will come with the necessary adapter to join the two hoses together.

25' Extension Hose

You can also purchase a separate 50 foot hose.

Q: Can I use the MTM Hydro 3.0 Turbo Tip Nozzle on the Simpson Model MSH 3125-S Washer ?
Also, where do I find a tank for the cleanser so the siphon tube can go into and does it mount to the washer ? Thanks a lot

by Pat from New Jersey on July 14, 2014

A: Yes the MTM 3.0 orifice turbo nozzle would be the correct item for you. We do not sell add on detergent tanks here. I would recommend reaching out to the folks at Simpson to see where one can be purchased. Their number is 877-362-4271
by Brian, Product Expert
Q: Does the Simpson 3100 have a container to put cleaning detergent in.
by Jason from Louisiana on March 09, 2014

A: No this unit does not have a detergent tank. It comes with a downstream injection system, which is a siphon hose running off the pump. You would put the siphon hose in a detergent of your choice and it would draw chemicals when using the black tip.
by Brian, Product Expert
Q: I bought a Simpson 3100 from Sam's that was the display model, when I got home there were no spray nozzles. I think the bag blew out of the pickup. Anyway, I need to get tips for the sprayer, a model MSV3100 p/n 60464. Are tips available separately?
by John Owens from New Mexico on August 30, 2011

A: Yes, there are definitely spray tips available for purchase. I am posting a link below to the correct size tips you would purchase for that model:

Q: I'M CONCIDERING BUYING A SIMPSON 3100 MODEL MSV3100. DON'T KNOW ANYTHING ABOUT PRESSURE WASHERS.
I'M A FARMER AND I WILL USE IT AS AN ALL AROUND PURPOSE WASHER. IS THIS A GOOD PRESSURE WASHER

by LARRY GUNTER from South Carolina on March 26, 2011

A: Simpson is one of the first and largest pressure washer manufacturers in the U.S. and they make great quality pressure washers. Also, this model has a Honda engine installed on it which is one of the most reliable small engines available for pressure washers. You can definitely use this model pressure washer as an all purpose machine that would be capable of handling a variety of tasks
by Brian, Product Expert
Q: I have moss buildup on my concrete patio which is very thick. I need a pressure washer that will clean down to the concrete in a fairly short period of time. I've used the 2600 psi versions before but they do not cut it. Any advice?
by Robert Olsen from Washington on March 26, 2011

A: I would definitely recommend using a pressure washer with at least 3000 psi. A 3000psi pressure washer is normally sufficient for cleaning concrete. Given the amount of moss build up that you have and depending on how large of an area you have to clean, you might want to purchase a pressure washer with a psi rating between 3400-4000 psi to complete the project as fast as possible.
by Brian, Product Expert
Q: I bought a 3100 psi Simpson PW @ Sam's Club. Can I get a 50 foot hose with fittings for this machine from you/Simpson?
by Bert Solomon from South Carolina on March 26, 2011

A: Yes, we carry a 5/16" 50' hose by Legacy.

I posted a link below to the hose I am referring to:

The MSH3125-S Simpson unit has a durable Honda GC engine, which has earned it's place at the top of the small engine heap for being quieter and easier to start than other engines in its class.

Amongst all of the consumer grade pressure washers we carry, this model has been by far the most reliable and durable pressure washer in this category.

Put it all together and you wind up with a very versatile pressure washer at a very reasonable price.

Lasted Twenty Minutes
Purchased it from a chain store last Black Friday. Stayed in box till last weekend. Within 20 minuted of use, there was a separation between the silver and gold parts of the engine and the water flowed out like a fire hydrant. The store gave me my money back, although I'm considering giving it another try.

I assumed the Honda engine would be bullet proof, so I'm not sure if I should try a Briggs and Stratton, etc
Brian, the Pressure Washer Expert
Product Expert
Robert,
With respect, if water came out perhaps it was the pump that separated from the engine? Water doesn't run through the engine on any of the gas units I am familiar with.

Honda engines have earned their reputation as the best on the market. There are, however, different grades of Honda engine that may affect your buying decision. Their "GC" engine that's on this unit is consumer grade. It's a good engine and will perform fine for most homeowner tasks.

The Honda "GX" engines are commercial grade and have heavier duty components and will last longer- but they are more expensive.

My deck and ramp had years of sealer and stain and looked horrible with uneven wear spots, damaged surfaces, and stains. I used my Simpson to remove it all in one step). It worked and it's down to the bare cedar wood and staying that way!

Bad Start Good Ending
When the box arrived the top of the box showed oil had soaked through it. Yes, oil... After opening it up I had determined that the oil filler cap was loose, causing whatever oil remained in the engine compartment to come out. The instructions said the engine is empty of oil but I wouldn't expect it to be completely empty. I also wouldn't' expect it to have that much oil in it. I would also expect that handlers would read the side of the box that says "This end up"!

Engine Defect
After a couple of dozen uses the pull cord started recoiling back to the engine with a tremendous amount of force. It nearly broke my hand. I read on other reviews that there is a common engine defect with the exhaust valve. I bought this because of the reputation of Honda engines. I'm very disappointed.
Pros: Features
Cons: Unreliable
Brian, the Pressure Washer Expert
Product Expert
Archie,
It's a good idea to let the water run through the spray gun for a minute or two each time before you try to start the engine. This drives all of the air out of the pump, making it easier for the engine to turn over since the pump and engine are connected directly.

If you continue to have problems with the Honda GC engine while it's in the 2 year Factory Warranty period please contact the Honda Small Engine service location in your area. You may find this link to the Honda Small Engine Service Locator helpful.

We don't recommend trying to service the engine yourself during the Factory Warranty period since it might void the warranty.

I've used this several times over the past few weeks and it's great so far. Assembly was a breeze. The instructions are clear and the parts are marked to avoid confusion. The motor oil was supplied, and the container holds exactly the amount you need to add.

I've used it on my siding, picnic table, cement stairs, deck, trash bins, gas grill lid and driveway so far I'm always looking for more things to clean, it's so easy and fun to use.

Glad It's In One Piece
So far the product is great. The only problem I have is with the shipping. The power washer came fast but the packaging was terrible. Oil from the washer leaked in the box and by the time the box reached my front door it was ripped and falling apart.

I'm not sure if the issue is with Pressure Washers Direct, Simpson, or Federal Express. For the price of the equipment one would think the security during shipment would be more of a priority.
