What do you do with the siphon tube if you dont want to use detergent on a job.

Do you leave the siphon tube connected to the detergent inlet and let it flop on the ground, or do you remove the siphon tube and plug the detergent inlet hole, because this unit has no detergent tank.
Asked by: Alex
Take the tube to the side. Most Pressure washer machines are made like this. Not sure why. As an engineer and mechanic I Believe it is too cut cost for the creation process and the engineers figure the consumer has common sense to solve this issue on their own.

Does this unit have an adjustable pressure regulator?

I was looking at a unit that boasts a "Spray Gun-convenient adjustable pressure regulator to selcect correct pressure for the cleaning application; adjust pressure from 1000 t0 4200 psi with a simple twist." Does this unit have something similar where I can adjust the psi without changing the tips?

4,200 psi 4.0-GPM OHV Engine Triplex Pump Gas Powered Pressure Washer is rated 4.5 out of 5 by 40.
Rated 5 out of 5 by from Best pressure washer i have ever used i did some... Best pressure washer i have ever used i did some extensive research before i decided on the purchase.Out of the box 123 up and running.Very easy to start and move around my cleaning time is cut in half due to the strong output of the machine.Iwould definitely recommend this machine 100%.

Rated 5 out of 5 by from Amazingly powerful and awesome power washer! I bought this unit to replace a smaller Karcher pump with Honda engine that quit work (broken shaft). I have used a $6,000 trailer mounted Shark belt driven steam/power washer that is not as nice and powerful as this Generac unit it. The Triplex pump is awesome, excellent pressure and very good GPM. It isn't all about pressure when washing heavy equipment, you have to have a large volume of water and this pump does it. I'd recommend to anyone who isn't just washing a deck and needs some power. The only issue so far is that the paint is burning off the exhaust but not really an issue. Also it is Made in USA.

Rated 4 out of 5 by from would be 5 stars but for poor Generac customer service The unit arrived in good condition. Washer works very well and with the 4000psi/4gpm rating cleans very fast. Only issue was that upon first use the "Unloader Adjustment" came lose (near zero pressure from the unit). The jam-nut was not fully tight. I requested the adjustment procedure from Generac and met a wall. After repeated attempts to get the needed adjustment instructions from Generac resulted in no success I contacted Annovi Reverberi (the pump manufacturer) and within minutes had the entire service manual for the pump. The adjustment to correct the problem took less than ten minutes but required a pressure gauge. Bottom Line: The pressure washer quality is very good. Customer service needs improvement! Kudos to Annovi Reverberi!

Rated 4 out of 5 by from Great performance out for that axle snap ring!!!! MINOR CON: Adding oil to the motor is a bit tricky given its placement. MAJOR CON: Vibration from motor caused snap ring to come off axle, Axle vibrated out and unit collapsed. This was on first use on day 1. Ring was unable to be found (probably "blown away"). I was very annoyed that I had to stop, clean up and go buy one on my new $900 unit. LIVID. With my new 25 cent snap ring now installed on day 2 being cautious I was looking for it and the snap ring again came off the axle. NOTE: axles and wheels come assembled on unit. Problem seems to be a design flaw given the obvious vibration when unit is used. . PROS: As advertised it is a VERY powerful pressure washer and it cut the time down on my job significantly. Starts easy but you need to be able to give it good rip on the pull (older users may be challenged). Performanc was excellent.

Rated 1 out of 5 by from Had high expectations, but am very disappointed by Generac The design and features of this product made me order this pressure washer. It shipped directly from Generac in WI. But when I received the pressure washer I found out, all of the accessories (Pressure wand, Suction hose, Nozzles,) were missing. Guess somebody at Generac screwed up big time. So, I directly called Generac customer service and informed them about the missing parts. They told me it would take 2-weeks to send me the missing accessories. Completely unacceptable! It actually took Generac almost a month to ship the missing accessories. I am glad I returned this Pressure washer to Homedepot and went with a Dewalt/Simpson instead. Due to this experience I will never buy a Generac Product again!

Rated 4 out of 5 by from concerns over quality Powerful power washer. The only negatives I have are 1) I find the power waher hard to start. 2) Two of the four bolts that hold on the fuel tank on fell off after 15 minutes of use.and the other two were very loose. I would have expected better quality from Generac. This problem kept me from buying a Generac generator a week later.

Rated 5 out of 5 by from My crews love it! I have not used the maching myself, but I did unpack and assemble it which was a snap. Each person in my company that used this machine says it does a great job. That's music to my ears. We have only used it a few times, but so far so good.

Rated 5 out of 5 by from Excellent do it all pressure washer I opted to go with the 4200 PSI since I've got a 2-story house. The tip selection allows me to get the majority of the second floor without using a ladder. Variable pressure speeds allow me to adjust based on what I'm cleaning. I use this to clean my cars, UTV/Quads, driveway & house. It's amazing what a good pressure washer can do to restore dirty concrete walkways. This replaces an older 3000 PSI electric one. For my side by side this has cut my wash times from over and hour to being done in about 15 minutes! My only compliant is it can sometimes take a few pulls to get fired up. You have to let it run half choke with the wand open for about 2 minutes before you can take the choke off without killing the motor. It would be nice if you had an electric start version, not super hard to start but it's more convenient.
