Hello,
My name is Chris Tucker, ower of Apple Non Pressure Roof Cleaning Of Brandon Florida, a suburb of Tampa.
We have been cleaning fiberglass shingle, and barrel tile roofs w/o using any pressure for 14 years.
I have been helping people get started in Roof Cleaning for many years.
I am a roof cleaner, not a power washer.
Therefore my area of knowledge is confined to doing only one thing, cleaning roofs.
I can be reached at 813 655 8777 any Sunday evening.
I will be posting many roof cleaning related threads here in the future, and I encourage you to read them, and all the great advice and experiences of the other fine people who frequent this new forum.
Here, we will all be trying to advance the state of the roof cleaning art.
Personally, I find that the mind, like a parachute, works best when open.
The New Roof Cleaning Pump Of Choice
http://news.thomasnet.com/fullstory/464091/3286This is the new Delevan 5800 pump, 5.3 GPM open flow and 100 PSI capable.
Viton valves, Santopene Diapraghms, and poly body ensure great chemical resistance.
Performance like this was unheard of in a 12 volt pump years ago, when we started.
This will be a great roof cleaning and chemical spraying pump.
I predict it will become the inexpensive pump of choice for roof cleaning.
It also has 1/2 AND 5/8 Hose Barb factory options.
Hats off to you Delevan for listening to our needs.
One might notice that this pump will prime up to 14 feet!
What does this mean ?
It means that this pump can be used with an Apple Vari Flow system!
Below is the link to the thread telling you how to build this system
BTW, TWO of these pumps can be combined in tandem.
This means the outputs of the two Delevan 7800's are simply combined into a TEE having equal lengths.
This yields a pump system capable of 10.6 GPM, at 100 PSI!
How do we arrive at 10.6 GPM at 100 PSI ?
Simple, each pump has 5.3 GPM and 100 psi.
So, two pumps in parallel double the flow, and pressure remains the same.
Enjoy!
Chris
