Q: I am looking for a pressure washer that does not leak. I am on my second Husky (I know) and am tired of getting more water on my pants than on the work.

Is that possible vCard with this model?

by Jim Farrell from Maryland on July 02, 2016

A: I've only had one leak if the hose connection was not secure and I used teflon tape and that fixed it up nicely. You'll love this machine. It's a monster of a unit.
by Brian, Product Expert
Q: The Generac 6565 comes with a 1/4" quick connect correct.
Is the Generac compatible with the
MTM Hydro Long-Range Detergent Foamer Attachment (Cold Water Gas)-
Do I need an adaptor to work with the foamer? it states Includes Both 1/4" Male Quick Connect & M22 Threaded Fittings, but then it states

•Will not fit Generac or Simpson quick connect spray wands--What The flock!?


Also the General Pump Professional 4.0 Orifice Turbo Nozzle states "Will not fit Simpson or Generac spray wands" is that for a consumer grade PW that does not have the quick connect end?

Thanks again Mike.

by Brian Gillespie from Oregon on April 23, 2015

A: I apologize, the Generac couplers are to shallow to accept the standard quick connect plugs.

However, by simply purchasing the AR Plug, it will fit those wands. I have attached a link for you to view the plug you would need to purchase with those items.

Generac has a great reputation for their power equipment, and this newcomer should be no exception - we have received a lot of positive feedback on this model.

This pressure washer includes a Generac OHV commercial grade engine and an AR triplex pump.

With that being said, this 4200 PSI, 4 GPM unit from Generac is basically a professional-grade machine at a prosumer-grade price.

Met All Expectations
The only issue with the value is the machine is a bit pricey. It didn't help that a similarly featured Simpson 4200 psi model went on sale for almost $200 less shortly after my purchase. That notwithstanding, Freight shipping went swiftly and without a hitch. Due to my remote rural residence, I opted for Freight Terminal pickup. The shipper (Saia) was a pleasure to coordinate delivery issues.

Currently, I am into 5 hours of use and will be changing the oil today. Start up and use were... more

Good Product
Good quality product for the price. We will be using it for our business. It's not a belt drive but has good GPM and PSI for the price.

We have a smaller Generac pressure washer (the One Wash) that has been going strong for a few years - I would guess we used that unit somewhere around 500 hours and it still works well. Hoping this model will have some longevity as well.

Maybe You'll Get Lucky
So I bought this even after reading some bad reviews of it mainly to do with stalling when hot and hard to pull. But my unit did that one better right out of the box it wouldn't start not even a cough. So I went all over it and eventually found that the spark plug had been smashed to the point where there was gap. I regapped the plug and pulled until I found out the thing will not start on choke only run. Do you know how many pulls that took to find that out?

So now I'm happy it's running... more

Matt,
I am so sorry you've had issues with your pressure washer! Generac is such a large company that I'm afraid they don't keep their Service Directory as up-to-date as they could.

If you feel you aren't being treated fairly at the Authorized Repair location, please give me a call directly at 800-710-7499 or email me at service@pressurewashersdirect.com and I will be happy to ask our Generac sales rep to step in on your behalf. I will need the name & phone number of the shop, your invoice number, and the name of the person you're speaking to.

We appreciate your business, and apologize for any inconvenience!

Second Time In Use Though It Blew Up
first time I used it it was great. The 2nd time I thought it blew up b/c of all the white smoke. I needed it badly but had to take it to be repaired. Was not happy.
Brian, the Pressure Washer Expert
Product Expert
Charles,
I apologize for the issues you are having, however it sounds to me like there may have been too much oil added to the unit.

This would cause the white smoke you are referring to. Also, Generac does warranty the item for 2 years and should be able to help find out the problem. Any questions you can call me direct at 800-710-7499.

Not Flushing The Siphon Tube Causes Expensive Repair
This unit, like many others has a barb that you connect the chemical injection hose too. This barb screws out and under is a small spring and ball bearing approximately 1/4" diameter.

This often requires cleaning as it gets gummed up from the chemicals and will no longer suck the chemicals in. I took my barb out to clean the hole and ball but it sprang out and lost it. I called Generac for a replacement and they told me that I must purchase a new pump as the spring and ball are not... more
Cons: Generac Poor Customer Service
Brian, the Pressure Washer Expert
Product Expert
Vernon,
The pump on this model is made by AR. You may want to give them a call at 866-235-5112 to see if they have the part that you need.

A couple simple steps described in the Owner's Manual will prevent this from happening in the future:

Always use pressure washer-safe detergent at the proper dilution ratio. This ensures a good mix with the water flow. A too-thick mixture will not mix well and will be harder to rinse out of the siphon tube and siphon barb.

Once you're done soaping, always stick the siphon tube in a bucket of fresh water and spray until the water runs clear to flush the soap out of the siphon tube and barb.

These 2 steps should eliminate the need to disassemble the soap barb at all.

Vernon,
We are sorry to learn of your unit's issues. Please note that we do not personally manufacture the pump that is featured on our commercial grade power washers. Considering this, we are unable to provide individual parts for replacements. If you are interested in obtaining specific parts for the pump, however, we would recommend contacting the pump's manufacturer. If there is any other insight that we can provide regarding your personal unit, please do not hesitate to contact us directly at 888-GENERAC (436-3722). We do apologize for any frustration that this unfortunate scenario may have caused.

Awesome Product And Service!
First off....... This thing is a BEAST!!!! Definitely worth the money. I bought it primarily due to its 4 GPM rating and it hasn't disappointed. I was able to run a 20" surface cleaner with this machine and had GREAT results! I have used it for down streaming and can easily hit two stories with it. :)

I paid extra for lift-gate service and was glad I did. The unit was quite "hefty" to say the least. Everything was included as advertised and start up was achieved after 3... more

I have 5 powerwashers due to my job. I only bought this Generac because of its sale price, and I could not be any happier. It does have 4000 psi and starts up first time.

I am leary about the duration of the pump, but so far it's working as designed. I have no regrets and would definitely buy another one. Generac is well known for their generators, so I decided to go to their line of power washers.

So I purchased this pressure washer simply for the 4200 and the 4.0 gallons per minute but I'm so happy with everything about this machine!

I have used many other gas pressure washers with Cat pumps and big PSI that cost almost double the amount of this Generac and let me tell you I would buy this over them every time now that I have used this machine- this is just the best value out period!

I seen that some other people had problems starting their unit, let me tell you I have never had... more

So Far An Excellent Choice
Just used it for the first time. Very difficult to start the first time. Followed the instructions and tried to start it 20-30 pulls later, nothing. Open the choke fully, instead of closed, fired up on the next pull. Started the first pull about 20 minutes later. 4200 psi has quite a kick to it. I purchased a pressure gauge so I could accurately adjust the output pressure. Cleaned my concrete patio at full pressure, turned the pressure down to 3100 psi to clean patio furniture and table.
