I'm waiting on Bob w/pressuretek to call me back as we speak.

Going to buy two of those bad boys today!

On the RCIA board, Russ say it costs $229 per pump.

This is going to be KICKA$$!!

I won't need to upgrade to the Yamada pump, these
Dual FATBOYS will be all I'll ever need for roof cleaning.

THANKS CHRIS!

I have 10 gauge on now.

Dual FATBOYS will draw as much as 50AMPS @ 100psi!!

Damn that's a lot of juice!

My battery is strong, it should handle it. 770CCA/950CA

After further research I will have to upgrade my wire to 8 gauge

When I install my FATBOYS I have decided to plumb them together
but not on the same switch like I had my 5gpm 60psi Delavans.

They will be on separate switches and if I run them together, I will run
them through two 3/4" hoses separately with two guys. The only time I
will run them together through one hose is for filling up my chemical
tanks with no nozzles, just open flow.

This way they will not be running at maximum pressure.
If I keep them running at 60psi or less, they won't draw as much amps,
saving them from overheating, blowing fuses, and killing the battery.

I will use large nozzles, #50 at least, #60 maybe, 1/4" barbs, or 3/8" barbs.
I'll experiment to see which one gives me good distance w/o putting
too much strain on the pump. I ordered 8 gauge wire and 3/4" poly quick couplings to
change out my 3/4" stainless steel hose reel swivel (which is getting rusty)
I can not see using any hose smaller than 3/4" for a pump that pushes this much volume,
1/2" or 5/8" would cause the pump to draw more amps and raise the pressure beyond 60psi, decreasing it's life.

Of course, this is all in theory, according to the performance chart. I won't know until I actually use them.

It is gonna be Interesting ?
Personally, I think you will need more then 60 psi to push that much flow, but we will see ?
