food coloring injector ratio

Ok so just did the food coloring test for my injector.
i put blue food color in a gallon pail and dropped in the injector
squeezed the gun trigger with a wand on it, no tip until i started seeing blue
then filled a 5 gallon bucket 2 and a half times.

i tilted the bucket untill all color was gone.

so i can conclude that my injector is about 12.5 draw or maybe a little less because i tilted the bucket to suck it dry which wouldnt normally happen if your
not near your rig...

is this ok for a draw? would the draw change with a soap tip?

so for example now if i needed to down stream 40 to 1 how would i do that?
just making sure i understand the ratio porocess

thanks
 
Get a 24 oz drink bottle drop the injector line in it if it will draw at least 24 oz in 60 secs you are good to go.The just do the math like 1 gallon of cleaner to 4 gallons of water.Then do some division some how lol.Most injectors draw 20-1
 
The way I do this is I get a quart measuring cup (in ounce increments or 2 ounce increments) and cut a short hose for the injector.

Get the nozzle you will be using mostly as there are different companies making soap nozzles and there will be different ratios based on the orifice size. A lot of us don't use the soap nozzles so pick the nozzles you will be using.

Make the injector hose about 1.5' long and fill it to the top line that is measured.

Place the container of water somewhere where it will be about waist high and stable.

All you have to do is pull the trigger so the injector is pulling (sucking sound) and then lower the hose into the water and see what time it is on your watch. I usually wait until the next new minute then watch the liquid lower and watch the time.

When the minute is up, pull the gun up out of the water and let go of the trigger.

See how many ounces are left in the container and subtract from the full amount to see how many ounces you pulled.

Multiply your gpm's by 128 and that will give you the ounces per minute your machine pumps.

Divide that number by the ounces your injector pulled and that will give you the ratio.

Ex. 5.5gpm x 128 (ounces) = 704 ounces pumped by machine in 1 minute
704 / 20 ounces (what my new injector pulls) = 35.2:1 so my new injector pulls 35:1

Hope this explains it.
 
Chris I will Have to read that thread a few times. But you stated that you do not use a soap nozzle to draw. So what are you using then?
 
The house wash nozzles I use are 1540, 0040 most of the time.

The 1540 is for soaping close up and the 0040 is for spraying up high like 2nd and 3rd story eaves and up high on walls, the fan pattern will only spray up so high.

They will pull soap nicely.

Nozzles like the 1530, 1520 and smaller size orifice (3rd and 4th number on the size like 30 and 20 are the orifice size) will pull less chemical than the larger orifice sizes like the 40 and 50 and larger. I think that the soap nozzles are like size 60 or 65 orifice.

Oh OK.. i use a 4 way j-rod with a 2510 2540 0010 0040 connected so i can switch from nozzle to nozzle easily...
 
Fill a gallon jug with water and weigh it.
Weigh an empty 5 gallon bucket.
Start your pressure washer. Drop the injector tube into the gallon jug.
Capture your spray in the 5 gallon bucket for 30 seconds to a minute (the time is not important).
Reweigh the gallon jug and the 5 gallon bucket.
Divide the change in weight of the 5 gallon bucket by the change in weight of the gallon jug.
That will give you your injector ratio.
