 for residential the bigger the better, once you used 8 or higher you will never ever go back to 5 I promise you.

Honestly I would like to have about 15 - 20 gallons per minute.


 15-20 gpm??  Holy chit, you'd have to carry "flash flood" insurance biggrinbiggrin 


 Gary their has been times when I washed house their would sill be water running down the road behind me.

I think after you reach about 10 gpm it will be time to move up to 1/2 hose and all bigger fittings.

I ended up with a 3700 psi, 4 gpm, with a 13 hp honda. Now in the market for a descent entry level surface cleaner. Any suggestions for the specs above? (Ray...do you have one laying around your shop that you need to get rid of?) biggrin

My PW is 5gpm 3500 psi and my Whisper Wash Classic works great ... PT has had it on & off sale the past couple months for $597, they've also been running some free shipping deals.

the surface cleaners with 4 spinning casters are far better than fixed wheels, no comparison

I myself have not. 100% of the guys here use a soft wash mix with various detergents and surfactants. Any sort of pressure is frowned upon within the roof cleaning industry. Just curious though, can you post a picture of what you are talking about?

Another forum? We dont use surface cleaners on roofs period. Go to the roof shampooing websites if you want to sell the roof surface damager/ not so cleaner thingy mobob. Sorry if I sound harsh but better me than some homeowner screaming and yelling becuase you just took 10yrs of life from their roof.

what ever you do, get a resevore for it.. i had a 25 gallon one for our 5gpm unit, but homes with well water couldnt feed it quick enough.. ive now switched to a 150 gallon tank just for the washer, and use the 25 gallon tank for soft wash mix (we downstream) 

 

its something you wont think about until the home owners water supply doesnt keep up and you turn a 2 hour job into a 4 hour job on waiting..

What's funny is the link to the Ultimate Washer Forum. I gotta hand it to Chris T and guys like Ron M who've put together forums like a hundred years ago. How many new forums have we seen pop up in the last year or two?

Ray, you get what you pay for with surface cleaners. Whisper Wash holds up well. Excellent swivel assembly. Not cheap. I just bought the Classic from PT. I think it was around $600.

General makes a Hammerhead. Either 18" or 20" and Northern tools sells them. I think Mike Derose just picked one up. Around $300-$400.

The hover types are better for residential in my opinion. Make sure your tips are no larger than 2.5's which should work well with your machine.

 I have 2 Whisper Wash units. One is about 10 years old and never had a problem, the other is 1 year old. The whirl aways have problems with their bearings going. You definately get what you pay for with surface cleaners.

That's what I started out with years ago and it is sufficient, if you don't run them all day 5 days a week. But I assume, you are talking about a direct drive. The next step would be to go up to a 5.6 GPM TS2021 pump with double pulleys. I have 2 of those with 13hp Hondas and also one ts2021 with an 18hp engine and a 16hp all with electric start engines.

I have one machine I am about to put up for sale locally, that has a 4.9 GPM pump / direct drive 13hp honda engine.

You can clean roofs with a 1.8 GPM ShurFlow pump and 1/4" hose and a little ball valve. You can successfully run a small pressure washing business, with a Home Depot $999.00 4 GPM direct drive pump on a 13hp engine. Anything less, and you are working way to hard for your money and if you have enough work, you will lose the difference in cost, between a $999.00 HD machine and a professional Pulley driven 5.6 GPM machine. They will all put out 3500 psi-if you want that. For most of my work, even with the 18hp I run at 2500 psi. The more psi you crank it down to, the less water flow you get. Water flow does a LOT of the work! {Just  a guess- a $999.00 4 GPM HD machine, set at 3500 psi probably puts out more like 3 GPM at 2500 you will get closer to the 4gpm. I have done tests with my TS2021 5.6 GPM pumps and the psi changes output drastically! Used in business, you will probably change out pumps [if you do it yourself ] at $100.00 a year. I have TS2021 pumps [which cost $600.00 each ] that have run steady for up to 8 years with no { sorry Mr Customer, but my machine is broken, I will be back when I get it fixed } I carry 2 machines at all times. A bolted down 18hp in the truck bed and a 16hp in my trailer.

Just like I have a double softwash 5gpm Delavan setup in my trailer. If one quits, I unplug the quick connect and plug it into the other one and fix or replace the broken one after work. Some things that appear to costly in business are really the cheaper way to go in the long run-besides having the pleasure of working with good equipment.

I bought every pressure washer used and sold the 4gpm pumps they came with and replaced them with new TS2021 pumps. Actually, 2 I got at Home Depot, that were returned $999.00 machines marked down to $600.00 and replaced the pumps. The 16hp I bought used as it is and the 18hp I built from an 18hp motor, about 7 or 8 years ago. Everything was new except the motor and NOTHING-not even the unloader, has ever broken [oh ya, the belt did twice. It uses a wide toothed belt.

I use all General TS2021 5.6 gpm pumps and that's after trying most everything since 1989.
But I have never had larger than 10gpm / 20hp Honda.

OOPS, Didn't notice I had already answered this!

Mike, have you used your hot box yet.


 No I havent! Believe it or not. No gum removals yet. Havent used my 20 inch SC either, my 4gpm doesnt push it. Still using my trusty lil 12 inch, and I'm on my second one now, get about a year out of it then have to buy a new one.

I'll be trying out hot water later this year when it gets colder, see if it makes a diff.
