I will check about the soap meter control on both.
What about Honda vs. B + S?
dELCO HAS A TWO YEAR WARRANTY ON THE CRANKCASE AND LIFETIME ON INLET/DISCHARGE MANIFOLD
Delco has auto burner control.

The attractive features of the Largo (to me ) are:
- 20 hp B+S and the 6 gpm.

I like 6 GPM for flatwork. Is 5.2 gpm plenty for flatwork?

Once again. Thank you for your opinions,warnings and advice. I absorb everything.

if you have any direct questions about the LARGO just ask them on this post.
I talked to a salesman today and he is our newest member.
He should be looking at this post soon.
 
Ron,

I talked to Mike at Largo. He was knowledgable and gave good advice. I will be talking to them today. I am going to order a Maintenance Manual that they sell that is supposed to guide you through most issues.

Thanks,
Scott
 
Scott, I spoke with those folks on Wednesday, I also plan on getting one of the manuals, sounds like it is full of great information. I had called about a new pump and he mentioned the manual to me.
 
The pump you are referring to is rated at 5.6 GPM and 3500 PSI. If they are getting 6 gpm out of it they are over clockingthe pump by about 10%. That means, it is made to run at 1750 RPM, but is probably running at about 1900 RPM to make 6 GPM. I hate Briggs engines, but they seem to be the standard. They would need a 20 HP motor to run the pump at the higher speed. They also usually come with a higher amperage charging system. as for the 12 volt VS 120 Volt argument, I have two and have no more problems with them than people with 120 volt systems.

After being in the service department for 25+ years, I can personally vouch for the 120 volt system. They don't depend on as many variables to run properly. A 12 volt DEPENDS on the battery, battery cables and connections, the charging system on the engine,which, in itself is a source of many variables, the ambient temperature,a cold battery is weaker,like a baby depends on a mothers milk. With a 120 volt, you've got a durable generator and a belt. As long as the engine runs at the specified speed and the belt is tight, the rest is exactly the same ( motor, transformer, fuel pump, etc.). Let the voltage drop off for any reason, and a 12 volt could fry a transformer or solenoid coil. The electrical components on a 120 volt are also less expensive to replace when the time comes. I have seen 10 year old 120 volts running just fine. As a side note, you guys with 12 volt systems, as a part of your maintenence program, when you do your tune ups ( once a year), check the brushes in your motor if they are accessible. If the carbon brush wears out and the copper wire hits the rotor it could burn out the motor. Brushes are cheaper than motors. Much cheaper.
 
Sticker Prices ?

Hi Scott,
I just bought a RK-43 in Jan. and it is a great unit, but more
importantly what I was looking for was service, and you won't find
better service.
As far as the prices you shown at the beginning, that is like
when you go looking far a car, would you pay exactly what the
sticker says ?
Just remember everything is negotiable...!

Take Care
 
Cleaner Times Article

For what it's worth, in the Feb issue of cleaner times,
a distributor of both systems says,"I have more problems with
120V burners than I do with 12V systems, For more detailed info
on the comparison they did on the 2 systems go to page 17
in that issue..

Hope This Helps....
 
Scott,i beleieve you cant go wrong with either machine both give you hot water and enough volume to be competitive,i however have had problems getting Honda to honor there warranty claims and they dont claim to have a warranty.

i will never purchase another honda engine,myself.
 
Thank You! Thank You!! THANK YOU ALL!

I have finally made made my decision based on research, talking to reps., and the fine advice from the PRINCES OF PRESSURE! .

O.K. I am getting carried away with my discovery of color. Nonetheless, thanks to Tim Hayes, Warren Smathers, Ron p.,rfitz,
Russ Johnson,Scott Stone,Joel Hawley,Beth, Mike Hughes and many others.

Delco has been in business for 30 years, has popular support, a good reputation, and I now feel comfortable ordering from them. I must take responsibility for learning how to maintain this machine.I will order the maintanence manual and view the video tape.

The Largo has 6 gpm,but if I will be overclocking the pump it is not worth the risk. Landa has 12v systems. If they do then I just need to make sure I stay on top of things.

I had a good lesson today. I was pressure washing and my qc to my wand came loose and water sprayed everywhere. I reconnected the wand and water sprayed through . I lost my replacement toolbox on a job a couple weeks ago ,therfore, I did not have a replacement. Lesson: Be prepared!

Thanks again for helping me to make a decision that I feel good about.

Hello Clean Country,

There are three sources that I know about for pressure washing manuals.

1.- WWW.MOBILECLEAN.COM - That is the site for the company that manufactures the Largo machine. Call the "888" number and speak to Mike. He can explain the manual to you. It sounds very extensive.

2.- WWW.ENVIROSPEC.COM- Go to this site and request a catalog. You could simply call them as well. In the catalog is another manual.

3.Delco has manuals and videos. I plan to purchase that Beckett pump maintanence video.

I know that I will have a learning curve and am looking forward to it. Knowledge is power!

Good luck and email if you find out any other sources etc...

FIRST, unless Delco has done like another retailer I have not menitioned in the past, RW Beckett only rates their SDC 12 volt burner at 300,000 Btu. This is limited by the MAXIMUM capacity of the blower to move air through the system. In short, 300,000 Btu wil NOT give you 5.2 or more GPM AND 200 degree outlet temperature.

Common practice is in order to raise 1 GPM 140 degrees you need 100,000 Btu. In order to give you 200 degree temperatures, you must bypass water which will wear out your unloader prematurely.

SECOND, telephone support is not service. Try and see how well it works for your computer and attendant software.

A local professional pressure washer dealer will always be your best bet. They inventory the parts and have the specialized tools required to make your repairs fast and affordable.

If books were so good, then why are there not home lobotomy kits with telephone support?

This is not to say I find professional contract cleaners inept or unable to service their machines. In fact basic maintenance should be done by them to maximize their dollars. Annual maintenance or repair work as required is usually better done by a local professional pressure washer dealer. It is their business to keep spare parts in stock to repair various machines. If you, the professional contract cleaner, keeps spare parts in inventory to cover ever repair eventuality for your equipment; do you factor in the carrying costs of non-productive inventory when you do your P&L?

Our technical service manager has 30 years of experience in the field and on the bench diagnosing and repairing pressure washer problems. Our service manager has 14 years of experience working on all manufacturers' machines because, unlike most pressure washer manufacturers, we have a service department that due to the local economy most often smells like a combination of hog and chicken barn.

However, with all their experience they encountered a problem recently where working with an experienced pressure washer service tech they were unable to diagnose and therefore repair a recalcitrant machine. We paid for it to be shipped back to our plant where we were able, once seeing the unit, to effect the modification needed to make it function in the environment it was placed in.

FYI, our model SDC355H20, 4.8@3500, 12V skid will give a 100-110 degree heat rise, at 5.2 it gives 80-90 degrees. Our model, 4532H20, 5.2@ 3500, 120V skid will give 120-130 degree heat rise. The former is 300,000 Btu the latter 414,000 Btu. Our water inlet temperature is 50 degrees year round from our 300' deep well. I can fax anyone our test results so they can do their own calculations.

RW Beckett will send you service manuals for their burners and will even accept you at their schools. Virtually anyone can attend the Cat pump service school and I bleieve General, Giant, A/R et al
offer service schools as well. Get information from the component source before you get it from anyone else. Some one else will always make assumptions you know a minimal amount or will forget to tell you a specific thing. The component manufactuers have a fiduciary responsibilty to ensure complete information on their products. Third parties do not. Use any third part manual as a guide only. Chilton's are very good but never as good as Daimler-Chrysler/Ford/GM et al.

In short, to know is to grow. I hope this has helped some of you?

Cheers.

What Michael said is true.
All Hot pressure washers are rated at 200 deg. That just means that is what the high limit switch is set at. A true measurement is what amount the water temperature will rise as it runs through the machine. Michael says that on a 12 volt machien that they get 70 degrees. So if the water out of the tap is 70 degrees, it will be taken to 140 degrees. For me and what I do that is enough. In reality, I probably get a greater temperautre rise than that, but I could be pumping more fuel in to get the water hotter, or overclocking the heater.
Personally, I do carry 90% of the parts that I need to fix my machine, because sadly, I have found that I have a better inventory than any of my local pressure washer dealers does. I hate when they tell me that they don't have it, and can I wait a week. If they do that the chase begins. Now, I only go to them if I am out of something, and have three different places I can go to get the parts I might need in a pinch. When I do that I have to plan on paying double or more for any parts that I get, than what I can pay for it mail order. I even usually have at least one spare new pump and a rebuilt sitting on my shelf in case of problems.
It all depends on the philosophy.

ron p/anyone

if you lived in monmouth county NJ 07740
where would you take your wash unit to get serviced?
My Landa guy is 1hour 30 min away and works out of a chicken coup. He is a nice guy and so is his son[mobile service].
He is 3 times higher for parts then internet and dos'nt stock much unless it's landa.
The Hotsy guy is 1 hr 15 min away and ive never been their.
I have no clue who else is around.
Any ideas?
 
Forgive me if I am geographically challenged in my response. I see Monmouth County is located on the sea shore near Sandy Hook and south.

According to my reasonably accurate database of dealers in New Jersey you can try Kleen Machines in Roselle Park, Vachino & Sons in Elizabeth, Advanced Cleaning Systems in Sayreville, Performance Screen Supply in Freehold, Espo Cleaning Systems in Red Bank, Regal Cleaning Systems in Lincroft, Martin Cleaning Systems in Sayreville.

One of these guys may be able to help you, I hope. Let me know who you want to talk to or for more information. Feel free to call me at my toll-free number (888-826-9191).

Cheers.
 
thanks for the try

my landa guy is in sayervile and thats 1 1/2 drive.
The rest you posted are not shops but just cleaning guys.
Even some of them are gone now.
You are correct-i am 15 from sandy hook.
Anything south? Everthing you posted is north.
This is why i went on-line to buy my equipment.
I can fix or work on everything but the burner and im sure it's time for a tune-up.
I would hate to pay for a mobile service call that cost's more then the burner.
 
Try Chem-Plus over on the west side of the state or Accreditred Autobale in West Berlin or Atlantic Coast Hotsy in Toms River or Clean Chem in Minotola. All the names I have posted are to the best of my knowledge pressure washer dealers. Recently our new dealers have come from the ranks of the contract cleaner industry.

Hope this helps? Cheers.
