What? You’re not supposed to leave the mix on the house… you mean to tell me I’ve been doing this wrong all along you’re not supposed to just spray pure 12.5 on the siding and leave it LOL…ha ha just kidding, would be nice to not have to rinse though
I may play around with a 2 gallon pump up sprayer, hook it up to my remote valve. Force feed that bad boy.
Just an aside here, I found a 1/4" stainless 1psi crack pressure valve on Amazon for $46, I can’t believe the $110 version can be that much better. I bet it’s even cheaper if you dig around on Ali too.

@Thom we’ll let you test all the knock-offs to see if they really work. 
Certain things though you don’t want to do that for.
From what I understand, the threads are weird on the GP injectors and you need a custom size piece for the check valve. Correct me if this is inaccurate. That may be why they are so expensive. I have one of those injectors just haven’t had to time to hook it up and try it yet.
Your correct. They are in between 1/8" and 1/4". I e-mailed General Pump asking the thread size is no luck.
