How Do I Choose a Roof Cleaning Pump?

Hey!! Nice set up!! Can u explain the three tanks?

I just use two tanks now. One is for chems on the right and the other is for mix. The little one I had used to rinse with but have another system now. You can email me and I’ll send a video that shows how I set it up. sullivanroofcleaning@dwx.com

Just sent you an email!! Thanks again for reaching out!!

So as far as GPM go on a roof system. What is not enough? I’m looking at this system in particular vs the fat boy.

VS

Or

Plus the added pump in a box. I guess it would be cheaper to go the pressuretek route and just add my own hose reel and make a stand.

However the gen 2 pump comes with everything. So 4.7 gpm vs fatboy’s 7gpm.

If you check the latest issue of EClean Magazine, I wrote an article explaining the different types of pumps, advantages and disadvantages. Issue 48 I believe.

Sorry for resurrecting this thread, but I really need some recommendations. I want to get hot water (100C) to a height of about 100 meters at flow rate of 21 litres per minute and pressure of 1500psi. Can anyone help me with the right setup?
