Thanks for posting this on the premium side Aaron.  Far too many lurkers on the guest side these days.

If I read your question right, are you looking to draw from an SH tank and a water tank at the same time, ie having it 'mix' itself in the pump and hose assembly? (And therefore wondering where to add surfactant etc)

I wasn't aware guys were doing it this way. I'm using three tanks to get these results. Water, Sh, and Mix tanks. My set up is similar to Bruce's.

 Yes,

I'm not running this way (yet, although I've given thought to it).  We know of one vendor that is using an injection system, however; pumps in tandem should yield the desired effect.  For example, a 3 GPM pump for water (and surfactant etc), and a parallel 2 gpm pump for SH would likely suffice.  A third and even lesser flow pump could be used to insert surfactant etc although the more complex the set up gets, the more points of failure there are.  (I've kept mine simple so far for that very reason.)

Chuck - I know you use a parallel or tandem pump set up because you like the flow, right?  Can you provide some pictures? Do both of your pumps just feed in to a 'Y' connector as I suspect?

 

**edit** I currently run 3 tanks as well, 12% SH, roof mix, and water.

I'm curious to see different pumps working together. I hauled gasoline before ethanol was forced on us and initially the ethanol was loaded before the gasoline. Then they started loading them simultaneously and if 1 lane out of four was working properly it was a miracle. I would be hesitant to "mix as I go" so to speak because of the risk of equipment failure. Water pump fails and you're pumping straight SH. SH pump fails and you aren't cleaning the roof. Can you tell from on the ladder if one or the other fails? I'm not saying it can't be done, I have just had too many bad experiences with a similiar situation.

Yes

We have dual tanks, one for shingle solution, and one for tile roof cleaning. All chemicals are pre mixed, we just switch feeds at the pump.

We ''softwash" with the shingle roof cleaning solution. It is a little strong for softwashing as is, so we simply wet the surface down to be cleaned with water first.

We do about 85 percent roof cleaning only, and find this system meets our needs.

Is that 200" of 5/8 and what hose reel u running? U using that plastic swivel or ss? Thanks ordering my stuff today!!!

---

 Yes, it is nearly 275 feet of 5/8 hose on the largest hose reel made by Titan Products.

Swivels are ALWAYS a problem, sometimes we have stainless, sometimes plastic, depending on what they have when one wears out.

We have even stuck on brass swivels, in a pinch. 

Get the Titan aluminum reel, with stainless steel manifold, no need for FULL stainless.

 I am sure Lori already knows about this little trick when ordering Titan Hose Reels.

Extra nozzles always a great idea, they seem to get lost, LOL
