Is this possible???

[harveymasons]

Greetings all. I just bought a Briggs and Stratton cold PW featuring a b&S 10 hp motor w/ A&R pump The specs boast 3400 psi w/ 4.0 gpm.

Is this possible out of a 10 hp motor?? IF not how can Briggs outright lie and give these specs like that?? ISn't that false advertising??

I paid 799.00 no tax or freight.

SOmeone on another board told me those specs were impossible w/ the motor hat comes w/ it??

Any feedback?

Regards,
Harvey

Does it have a grearbox on it?,if so it may be able to handle it but not day in and day out.

 

[harveymasons]

no gearbox. Pump is mounted directly to the engine.

I am not looking to use the machine everyday but I do want it to last a very long time. That is why I bought a commercial grade w/ the A and R pump.

I plan on using it10-20 times a year. Do you guys think I need to buy that pump saver when I store it for the winter??

Regards,
Harvey

Harvey,


The 10 HP Briggs is not adequate for 4.0 GPM @ 3400 PSI.

 

[harveymasons]

When you say not adequate what do you mean exactly??

I won't need to use full pressure very often, in fact I won't be using the machine on a daily basis. Maybe 15-20 times a year??

Are you saying I won't be getting a true 4.0 gpm and 3400 psi when I have the preassure turned to max??

If so how can Briggs advertise something that is outright untrue??
Isn't that false advertising?? I mean if iyt is rounded off that is understandable ie. true gpm is 3.2 and they round to 3.4.

If youare saying the machine was not built to run everyday at 4.0 gpm and 3400 psi that is fine as I don't intendn to use it everyday.

What do you think???

HArvey

NO it was not built to run every day. Consumer units run fast and loose with the truth because they round up whenever they can They also publish theoretical values based on specious factors for performance based on theoretical engineering values; therefore they are not actually 'lying'.

Remeber this is the same group of pressure washer manufacturers that foist 'Cleaning Units' on the unsuspecting populace. According to CU theory the following are identical in performance:

1 @ 4000
2 @ 2000
4 @ 1000

All three are 4,000 CU's BUT....

in actuality they have the following Impact Force (a real hydraulic calculation available at Giant Pump's website)

3.34#
4.73#
6.68#

Or to put it another way the 4 @ 1000 will clean twice as fast as 1 @ 4000 unit. Do yourself a long term favour and find a local professional pressure washer dealer to help you get the CORRECT pressure washer for your intended use; this will cost more money initially but save you in the long run.

OR you may be better served by hiring a professional cleaning contractor to do the job for you.

Truth is we can only give you our opinions and a few facts; you will buy what you want and I hope you do not learn an expensive lesson.

By the way, who looks after showing you how to set up and maintain your pressure washer? The safe operation and chemicals to use? Who performs warranty? Stocks parts? Provides after sale service? And so on.

Hope this helps? Cheers.

I'm still a bit confused, CAn you put it in layman terms for me??

With that Briggs and stratton machine what do you think I will be getting in GPM if not 4.0?? And what psi if not 3400??? The specs have not mentioned anything as far as cleaning units, I don't think they are using those as specs just 3400 psi and 4.0 gpm via Annovi Reverbi triplex plunger pump. How can that be a gray area?? Either it will give you 4 gallons in 1 minute or it won't correct?? Am I missing something here??? I think I will do the test w/ a 5 gallon bucket and see if the machine lives up to what it claims. As far as psi goes 3400 is far more then I will ever require I have been told so even if it was 3000 psi that still would be more then adaquate correct??

I am told that this A and R pump is a bit better then most of the consumer washer pumps that come w/ pressure washers. Again, this is not for commercial or everyday use.

As I said earlier I don't plan on using this everday maybe 10-15 times a year for my 3 properties that I own.

As far a maintaince I plan on doing it myself, doesn't seem to hard to change oil in the pump and engine.

ALso. Briggs provides a toll free 1800 # for any questions on setting up and or using the pressure washer. IE. dos and don'ts which I find quite helpful.

Again UI am no expert, and that is why I really appreciate your comments and thoughts.

HArvey,
Well you have been to two boards and received the same answer twice! Bet you try a third.

You ask the questions after you made the purchase, sometimes the truth hurts.

 

[harveymasons]

The TRUTH?? I WISH I CAN GET THE TRUTH!! lol

That is the problem. I cannot get a straight answer???!! The answer I am receiving implies that the people here don't know the answers to me real questions so they just dodge the question and talk about cleaning units etc....

All I simply want to know is for occasional use will this machine put out what it says it will and if not what do you think in actuality the output (gpm) is and if not 3400 psi what do you think the true psi is??

I didn't realize such a simple question would turn into such a nightmare. lol

I guess I will have to do the test myself w/ the 5 gallon bucket.

best regards,
harvey

If you want to know what the true gpm and psi are: Put a pressure gauge on right before the gun to check the pressure, and open the trigger into a 5 gallon pail for 60 seconds, and see how much water is in the pail. You can't expect anyone of us the know what YOUR machine will put out.

Here a few cold water units that are currently for sale on eBay:

9 hp Robin 4000 psi / 2.5 gpm General pump (Buy it now $799)

Troy-Bilt 9 hp B&S 3400 psi / 3.2 gpm AR pump Currently $610)

So, have you actually seen this machine? It sounds like the Troy-Bilt unit.

The laws of physics being what they are, if you want higher psi and have a smaller motor, you will have less gpm.

 

[harveymasons]

Hello,

Yes I actually just bought the machine. YEs the specs are almost indentical to the troy-bilt unit above except the troy has a 9 hp and the Briggs has a 10.

SO I guess the specs are very possible and very real based on the above.

YOu can see the machine I am referring to if you just goto google and do a search for Briggs pressure washer 1808.

best regards,

Harvey, Harvey, Harvey

Let me reiterate a few things...

Briggs Intek motors (as supplied on this unit) have a poor reputation; ask ANY small engine repair guy.

In some marketing math circles 3.2 GPM IS 4 GPM in the miracle of rounding.

10 hp gasoline = 6.67 ELECTRIC brake horsepower

6.67 EBHP = either 2434 PSI @ 4 GPM OR 2.7 GPM @ 3400 PSI

Please follow the math...

EBHP = (Flow X Pressure) / 1460; this formula is a proven electric motor/ hydraulic constant. Electric motor brake horsepower is used because there are International standards relating to the performance of these motors, regardless of country of origin. There are no such standards for small gasoline engines so you must use a factor to compensate based on real world models of EBHP X 1.5 = gasoline engine HP.

Therefore plugging in the 'values' supplied by the retailer you get either 4x=6.67 X 1460 OR 3400X=6.67 X 1460 where x is either pressure (former) or flow (latter).

Neither 4 @ 2400 nor 2.7 @ 3400 is what you purchased. As to my post regarding 'Cleaning Units' this was proactive to prevent anyone from being bamboozled by a marketing ploy.

Impact force was printed to show the value of flow versus pressure; again to educate the consumer.

Contrary to some opinions this IS valuable information that is NOT made available to the uninitiated.

After you have assembled your new pressure washer please make certain that you operate it in a safe manner and that every component is set safely. You can never be too safe.

Hope this helps? Cheers.

harvey.......if you are only going to do 15 or 20 jobs a year....i wouldn't worry to much about "gpm"..............as you have got 365 days to finnish them in...hope this puts your mind a rest.

cheers paul.

point excepted Paul.

thanks,
