We only clean tile and shingle roofs, so we went to a dual tank system instead, oner tank for shingle, one for tile.
Easier and faster for us.

The idea of mixing the SH with the water/tsp/surfactant just before the pump is an interesting idea. I'm a new company and small company. If I mix too much love for a job and can't use the leftover before the SH goes south I lose money. If I mix too little love for the job I end up taking time to mix additional love to complete the job and that also cost money.

I have a biodiesel operation where I do exactly what is being talked about here. I mix methoxide with the waste vegetable oil to create the biodiesel. A ball value is used to introduce the methoxide just before the pump. I control the flow by how far I open the ball valve.

I will have to experiment over the winter with a setup that will allow me to create my love at the pump.

When I started this forum, it was with the belief that ALL of us is smarter then one of us.
By all means, experiment !!!
A ball valve is not a linear device BTW, but it may be good enough ?
More precise control is had by using a linear type of valve.

You are right about the ball valve. It will not provide percise flow control. I started searching the internet for flow control valves. If you know of a source please share it with me.

Thanks.

Remember to look for something that will withstand SH ? Especially if you are using non-diluted SH?

Can you provide some details as to how you control the mixing with the dual intakes. Some pictures of your setup would be nice.

Thanks.

Will be or ARE? Remember, time is money. How many times will you need to re-apply?

im in the process im waiting for the manifold they are on back order so any time now and i will have pics for ya soon. they make yamada dual manifold the just dont make them in kynar so i have to modify it myself

Yes, I had considered using the Yamada dual mainfold.
It is only availiable in Poly, but MIGHT last awhile, if rinsed out after use ?

when im done with mine if you like it ill build you the parts you need to build your own using two kynar manifolds you could install them in less than 5min

I am going to work on getting a set up to work this winter. I am running the delavan pump.
I think the pick up tube in the SH will need to be one size smaller than the pick up tube in the water. And, install a metered flow control valve. I am going to try a manifold with "Y" connections. I think that would give better suction, and mixture .

Roof Clean USA-Dual Draw tm Quad-Chem Setup

roof cleaning Been there done that. Works but not as well as you might imagine. There may be variations of "CLEAN" on the roof at times depending on if you have mixed or unmixed leftover TSP in the tank bottom or OTHER cleaning agents.

Installing a return line with a AGRICULTURE style bypass Agitator will help you.

The "problem" we found with the vari flow system is left over chemical in 300 feet of hose.

We once cleaned a tile roof, a white one, really dirty.

We set our flow control valve for about a 50/50 mix.

Then, we did a shingle roof, and only needed about 30 percent mix.

WHAT do you do with all that strong chemical trapped in 300 feet of hose ?

Since we only clean shingle and tile roofs, and do very little other cleaning, we just use dual tanks of pre mixed shingle or tile roof cleaning chemicals, and switch the pump feeds.

BTW, poly is not "all bad", and will last awhile IF rinsed out.

Manifolds are cheap, at least single ones are ?

Sure, Kynar is better, but I have used Yamada Poly pumps for almost a year, by rinsing them out after every job.
