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 Mike, 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 Mike, 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 Mike, 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 Mike, 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 Mike, 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 Mike, 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:

Pressure Washers Direct Recommended

There isn't a big stretch between our "Better" and "Best" choices in this category. Both have good engines and good pumps.

However, this 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.

Cannot Connect Hose To Washer
I received the washer 2 days ago. I found that I could not attach the high pressure hose to the pressure washer. It is apparently missing threads. I contacted the company and they are supposed to be sending out a replacement hose. Waiting to use.

Philip,
That is very odd... I'm glad the folks at Simpson are taking good care of you. We will follow up and make sure this is just a one-time thing, and not a bad batch of hoses. Thank you for letting us know.

We appreciate your business, and apologize for any inconvenience.

Power Washed Down To The Bare Wood!
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!

What The...?
About 15 minutes into use, the pump blew apart. One bolt sheared, and others blew out of the pump housing where the silver part bolts to the pump. A piece of the pump broke off. Up to that point, things were wonderful. What luck.

Of course I can't exchange it. I have to wait for the podunk repair shop to evaluate, submit, get approval, see if warranty will cover, order parts, replace the parts, etc.... and of course, as of a week after I dropped it off to them, they have not looked at it... more

Stacey,
I apologize for the issues you are having with the Simpson unit. However, the unit can't be shipped back due to Federal Shipping regulations on Gassed items. This is why everything we carry comes with a full manufacturer warranty. It is pressure washing season, so many of the service centers are busy.

With that being said, they will take a look at the unit and make the necessary repairs as long as it is covered under the warranty and nothing was used improperly. Again, I apologize for the issues you are having, and if you are unsatisfied with their findings, give me a call directly at 800-710-7499.

Impressive So Far...
I am a normal guy, Joe Homeowner.... And all I had done so far was borrow my father-in-law's pressure sprayer every spring to spray the moss/algae/gunk off my cement patio and wooden deck.

So I did some research, bit the bullet, and sprung for this $400 sprayer... (I was expecting to pay $250-$300...).

This past weekend, I broke it in with a good 4-5 hour session cleaning off my patio. Then last night, I went for another hour and a half.

I must say... Its pretty impressive. Simple to... more

Things Done Right!
I needed to replace a worn out pressure washer that the pump had gone out on. Honda motor still worked, but I thought it was time to replace. I bought a new Black Tahoe for my business and need to keep that clean, wife's Audi and Corvette and really in a small town I don't want to spend 40 a week on washes.

This does a great job and I'm impressed. Honda is perfect motor and the washer eats up dirt. I should have bought the sidewalk attachment and ended up getting one at Lowes. Same... more
