Please forgive my ignorance of this topic, but I could really use some help.
I am trying to figure out what the most common, or preferred, method of chemical injection fittings are used. When you set up a new chemical system for a commercial or residential pool, how do you inject it into the main line?
Tap a check valve? Use a saddle clamp? Use some other type of clamp?
I appreciate any suggestions or feedback you have to offer! Thanks in advance!
