Math is not my strong suit, if you all could help me out.
I just tested my remote injector setup. With it off the pump puts out 5.5gpm, filling a Home Depot bucket in a minute. I checked with another 5 gallon container with graduation marks and it overflowed with 10 seconds left.
I put exactly one gallon in the container, switched on the remote and it took 5 cups in one minute.
Can someone please do the math?
If my calculations are correct it’s putting out .7% SH at the nozzle. Maybe.
I use straight 12.5% in the draw tank. It isn’t always effective, although the hose did flatten toward the end. I’ve since installed polyethylene tubing.
For draw volume…
You already know how long ot takes to fill bucket with no inkector drawing.
Now on a different filled bucket drop your injector hose and fill bucket.
Then with a measured jar fill the bucket.
Now you have your draw
If my calculations are correct, you have a 15:1 injector and 0.83% hitting the surface.
Just so someone else can correct me if I am wrong
Your bucket test was 5gpm in 60 sec. (128oz x 5 = 640oz)
Injector pulled 5 cups in 60 sec. (5c = 40oz)
Subtract your pulled (40oz) from your total output (640oz) = 600oz
Then divide 600(oz) by 40(oz) = 15
Your injector is 15:1
Now divide 12.5 (%SH) by 15 (injector) = 0.83
Here’s my take: 5-7 minutes is perfect because you can soap more house. Smaller houses you can soap two sides at a time sometimes 3. Large houses you can split into 1/3rds. Mist it all on the way back around, start rinsing. If most houses take more than 1.25 hours, the strength might be too strong or you might have too much soap.
Start on the most shaded sides, work toward the sunny side.
I like apple wash. I like the smell and the marker. I only use it with my 12 volt though. when downstream I use elemonator or cherry snotmenade. what about the apple wash do you not like
What tip are you using to do this test 5 cups is alot unless you got a second story shooter tip it will pull more soap. Do the test with standard black soap tip. But in the end it doesn’t really matter pressure washing will never be a exact science
