That is very interesting Bruce, that you are running the Fat Boy 12 volt roof cleaning pump for so long. Many 12 volt roof cleaning pumps will overheat and fail, if run for more then 20 minutes at a time. The Northern Northstar Pumps are made to run for a long time.

I gotta say, I have always preferred 12 volt. They last a long time and I have never had one overheat. I have a nice compressor/ pump setup and it works fine as well. I just really like the peace and quiet of the 12 volt.

 After about 20 years of cleaning roofs in one place here in Tampa, we are almost always busy, and feel no need to do any special marketing.

Yes, 12 volt pumps are quiet, very quiet, and air pumps are noisy, but this noise has often got us work 

IMHO, this is something a new comer to the roof cleaning business may want to keep in mind.

I'm with you Chris,..I like the nice industrial sound of equipment running on a job,...and seeing how I use my 20 HP Honda running an 8 GPM pump to keep everything wet,...I have lots of noise going on,Ha,Ha,..

 I say, when cleaning roofs "Be loud and Proud", because it attracts attention, and attention can attract customers

Hi Chris,
This is the post I was looking for with the info about the 12V pumps,
Did you ever get anywhere with the pump guys with the changes to the pumps?

 I did meet with the Northern Tool Pump Engineers, and made my suggestions. if they will implement them or not is anyone's guess.

They did seem very interested in my suggestions for a better roof cleaning pump.

So is their standard 7gpm 60psi as good as better or worse than the fatboy.
I see they sell replacement head units for a good price.

 Better is a relative term, when it comes to 12 volt roof cleaning pumps, and you must ask yourself, if you really need all the flow of a fat boy or not ?

Tell me more about your needs, and where you live at ?

Hi Chris,

We also use the pump to apply chems for softwash on stucco.
So we need high flow for reach with the fatboy,
Ideal world would probably be two pumps one for reach and 1 for roofs only with less flow.
If you were to use an electric pump what flow would you recommend for roofs only.
I just purchased a new van and ordered a 8gpm Pressure pro for softwashing but just wont have room to put an air compressor into the van as we do need a generator for the gutter vac system.
So the electric pumps must work for now and just looking for the best must versatile set up i can get.

 I think 5 gpm is plenty of flow for cleaning roofs. Yes, The Fat Boy has more flow at 7 gpm, but this extra flow will make the pump cycle on and off too much, unless you  use a big ass nozzle, then you waste chemicals and get excessive run off, especially on a tile roof.

 

 

I'd find room for the compressor and air pump,..that will be reliable and do anything you ask of it when you need to apply a strong chemical at variant flows.

There's always room,Ha,Ha,..

Just a thought. I bet if this new pump were going to be a 12 volt battery operated pump and not require a generator, there would be a lot more interest in it! Most of us use these pumps for their simplicity and cheap replacement / repair costs. My guess is also that if anyone were to decide to add the generator, they'd use the superior air pumps, like Apple Roof Cleaning Tampa uses??
I also like mine to be quiet, as a generator sounds just like a pressure washer and that's what listeners nearby will assume is taking place. Just my thinking???
I KNOW I'd be very interested in an improved 5850 Delavan type pump!!!
Until something similar, but better, comes along, I'm extremely satisfied with my 5850 pumps. I have 2 complete pump setups at all times and if 1 quits, I simply quick connect right to the other one and rinse the quit pump as well as possible. It's usually the demand switch and that's a quick $20. + replacement!
Well, My wife is calling me. We are heading off to the theater to see the movie "BIG EYES"

 Happy New Year Chuck 

You use the smaller delavan 5850, not the Fat boy's, right ?
