Looking at a 29psi cf valve for my backpack sprayer, but what is the pressure in the smaller sprayers. Is 21 too high?

You might be pumping a while. I used one of the 15PSI ones and I sometime I had a hard time sustaining the PSI as the container got lower. Your experience might be different, depending on your sprayer. The 15PSI worked just fine for what I was doing with a handcan and I selected a nozzle, based on the psi and desired output, that paired well for my task.

Thanks this is exactly what I was after. Didn't know if it would work or not. I know the 29 is good for the backpack, but the 21 I guess I have no need. I'll just order the 1. Perfect!
