Roof cleaning nozzle tips

The other day I went to clean a roof and forgot my roof cleaning JROD with all the .30 orifice tips on it for my 5800 pump. All I had was my house washing JROD so I used the 2510 and loved it! The smaller orifice coated more evenly and got the soap more agitated for better cling, I got about zero run off and used half the mix. But the down side to it is it builds up too much pressure and triggers the switch so you to get a consistent stream and it obviously is horrible for the pump.

So what are you guys using for tips? I watched a couple videos where they seemed to just be misting it on... Is that the upside to air driven pumps?
I have an accumulator tank coming to see if it will help any. I also have a fat boy I need to set up soon as well.

Thanks,
Quinn
 
You're lucky you didn't burn the pressure switch up on your pump. Don't use a smaller nozzle until you get your accumulator mounted.

30's, 40's, even a #9....just depends on the situation. 1 screwdriver won't work with all applications....neither will 1 nozzle.

Life lesson #537

One of the many things I learned from Doug was to buy the accumulator when you buy the pump.

Make sure your tip size matches the gpm of your pump, HOWEVER also remember that what you are getting at your gun may be as much as half of what you would get at the head of the pump. ALSO as you go UP you will increase head pressure. ( one story, two story, three story) Do the five gallon bucket test up on a roof and see how much you fill the bucket in one minute with no tip in the gun. This will be your GPM and then get a tip that matches that GPM. EXAMPLE a 5 gpm pump at the open head of the pump may only give you 3 gpm on the roof after 300' of hose and going up 10 or 15'. Watch these numbers closely.

Or just switch to an air pump setup and use any size orifice you want from the finest possible mist to truly massive flow depending on the pump and compressor you buy. No accumulators, no relays, no switches and no pump failures. More distance, longer reach, more reliability, more flexibility.

Great stuff!!
 
what is this accumulator you guys speak of.. i just setup all my stuff with a shurflo 3 gpm pump, 300' of half inch. the tip i originally used was not spraying evenly. (was weak in the middle of the stream and heavy on the ends). ended up just using a DS injector black tip and was able to lay even fan/stream.

i obviously am putting my pride to the side, and willingly acknowledging that i need some guidance. Im new to the roof cleaning, and learning tons on here, as well as first hand experience on my own roof.

any and all advice is greatly appreciated

Accumulator is a bladder tank that gets filled by the pump, it reduces pump cycling. Lets you use smaller orifices without burning out the pump.

Dude I am right down the street from you. Ill have a full system in my garage this weekend refurbishing it for a new owner in Texas. You should come by and see the toys.

Good stuff AC, and so very true. Those little gremlins such as hose restriction and head pressure loss reduce flow more then some realize. Your method is "old school", and has been all but forgotten, but it is still the very best method to determine proper nozzle size.

I have to agree here that an air pump setup is the best, and most dependable roof cleaning pump set up that money can buy, within reason.
No accumulator bladders needed, use whatever nozzle size you want, whenever you want.

Did I just see Chris agree with AC?

OMG, I just saw this! Someone must have hacked my computer ?
Seriously, I don't always agree with AC on everything.
But, he is correct here.

I need to take you up on that, I'm always looking to learn something new or how I can improve
 
I'm trying various tips too! Roof cleaning is really picking up. I guess I'll get this accumulator, and keep adding to my air setup fund. In a minute, I'll be able to bypass the harbor freight 30 gallon and roll with the ingersoll rand 30 gallon!
