Just wanted to show a pic of it. Simple knob. 6 full rotations to open and close completely. So 3 turns is 1/2 strength to the Injector, etc.
Thatās a bit of a gimmick if Iām honest Dustin, just more things to go wrong and troubleshoot. The most reliable part and process is no part and process at all. The difference between 0.3% and 0.7% isnāt worth thinking about from any angle. Itās psychological, the reason itās psychological is because your only point of reference is the 12.5% label on your sh drum. Would you agree you have no idea where you are in terms of strength when you turn that knob?
Oh yeah absolutely. It for sure does meter the soap but I canāt calculate exact strengths. I just know if the house isnāt that dirty, I like applying less soap because rinsing is so much faster. The knob letās me adjust that .
Just helps dissolve the soap. I like it.
Youāve lost me Dustin, do you meter surfactant, sh or your actual downstream mix through that valve?
Sean up there getting me confused with this ādissolveā talk. Lol
My tank for house wash has soap and SH. Just before my injector Iāve placed a 1/4 meter valve to meter both
How about a 13:1 ratio ? Can you help me please
Your asking a question of a guy that posted 7 years ago. Iām not sure if heās still here. Ratios are unimportant. Tinker with a mix that works and stick with it
I personally go fo a 44 to 3 ratio. Fill an old macdonald cup with soap and youre good to go
George, what exactly are you trying to do? Downstream bleach? Degreaser? Oxalic Acid?
And on what type of surface(s)?
Thanks for the reply. Just typical sodium hypochlorite with my 5 gallon bucket. The reason why i replied here was because i heard if you downstream, you are adding more water on top of my 5 gallon bucket, lets say i wanted to do a 50/50 2.5 g of sh and 2.5 g of water, the downstream will add more to it. Then i saw youtube to add straight sh, like 5 gallons of it. I am just so confused because i would only start with 1.5g of sh and rest water. Maybe my mixs arent doing enough because its not that hot. Pretty much my concern is, how much sh should i add in 5 g bucket. I have a house wash tomorrow, and a restaurant coming up in two days. I been using the method of soft wash but in reality that method doesnt work for me because i have a downstream that manual says 13:1 . Also i always end up throwing my soultion away, and tips on not waisting so much? Usually when i see heavy stains, i use my pump up with straight degreaser and then my weak mix of sh 1.5g and rest water to surface clean it. Maybe i should downstream degreaser too. because no point of using sh on concrete if they aint organic life right?
I would cancel those jobs until you get a handle on how your equipment works.
How to mix chems is all over this forum and with the use of a search bar and less than 15 minutes of reading youāll see that there is no āgold standardā policy on how to do it. Each machine draws the mix differently. Each item being cleaned could require a different dilution of mix. Not all bottles of SH are the same concentration levels, so itād be helpful to you (and anyone trying to help you) to know what the supposed SH percentage is on the label of the bleach containers you are purchasing. Some guys buy 7% and others buy nearly double that. You canāt dilute both the same way and expect similar results.
Sounds like youāve been unhappy with the results your current mix produces. Have you tried to change up the mix ratio? Try adding more bleach to your mix and less water and see if that produces a better result. Double the amount of bleach. Try it. Triple the amount of bleach. Try it. And continue until you see favorable results.
For MY setup which is a smaller gpm machine, and a downstream injector I find that if I make my mix container 50/50 with 12.5% SH then downstream it from there (yes, downstreaming adds water to that mix and dilutes it considerably) I get what I find to be favorable results. But that doesnāt work for me for everything Iām cleaning, nor does it necessarily work for other setups out there. My current project is 4,200 sq ft of nasty, neglected driveway and the above mixture isnāt producing the results Iām wanting after surface cleaning. Iām actually dropping the downstream injector line directly into a container of just SH and surfactant and Iām only diluting it down by way of the injector. Iām seeing much more favorable results that way.
Youāve just got to experiment to find what works best for you and the way you do things.
Regarding storage of mix, it once again depends on your way of running things. Where you store it, how you store it, how quickly you use it, and other factors all need to be considered. For me, I buy my SH in 15 gallon drums and I use a separate 15 gallon drum to make my batch mix in. Iāll reinstall the plug at the top and Iāll store that in the bed of my truck for up to a week or so if need be, but I usually go through it faster than that. You can buy a resealable 5 gallon bucket, or a 5 gallon carboy container.
13 + 1 = 14
12.5% / 14 = ~.9%
Simple calculation to find your final percentage of bleach. Its useful if you run a 12v batch tank. I use a 3:1 bleach to water ratio to post treat bad concrete.
3 + 1 = 4 total units of liquid (gallons, ounces whatever)
Divide your undiluted SH strength (should be 12.5%) by however many total units of liquid (4 gallons in this case) and with a 3:1 ratio you get about 3.
This is as simple as it gets: put your injector into 12.5% sodium hypochlorite at a ratio of 13:1 youāre pulling 0.9% SH. Foundational stuff here, mixing ratios etc. anyone remember gallon man?
I can honestly say that I have never seen gallon man before you posted it.
now pecks and bushels, those are confusing. Iāve gardened my whole life and still have no idea how much a bushel is without a basket/box right there. This year I used a laundry basket (good portability while picking, doesnāt rot or rust, and it has lots of holes for hosing off produce). I filled four of those completely with tomatoes. We really should go metric, this stuff is silly when you think about it.
All I know are bushels of oysters and corn. The rest is lost on me. I googled it and now I have even less of an idea of what they are
wash house, if it turns in a few minutes, get the check, if it doesnāt add more bleachā¦
I washed it with regular water and nothing, then applied sh and nothing, hot water and nothing, d.i water and even scrub it and nothing. I think itās oxidation but customer insist its not because he painted the house 4 months ago . Idk what to do now, because now he wants me to scrub it and thatās more time consuming for the amount he paid me. Anybody can help me out ?. I thought it was dirt but nothing.
Thank you brother
Give him back his money and suggest he call a professional contractor in the area
