I love the x-jet when the time comes to use it, but it’s no substitute for learning to properly downstream and in this case could’ve saved a lot of headache.
You can check your injector ratio with a quart of water. Don’t need an entire gallon.
See Tim’s reply to the original post.
You don’t need to use 50 gallons of water and 5 gallons of mix. It’s a bigger sample size, but for our purposes it’s overkill. Use a pitcher for “soap” and a 5 gallon bucket to fill. It’ll take you less than a minute to figure out what your ratio is with the formula.
