Wrong. (re Nick) I began using Mauget in 1971...if done on the right day in the proper method...they don't need ANY psi. Gravity fed into xylem is plenty good enough on the proper day.
Mauget you can stick em and leave em and go about your business. They all work but Mauget is easier, cheaper, less expensive initial out of pocket and...again...much faster to complete and go on to other work/injections.
I have been to Ajet seminars and watched them agonize over completing the tedious process not to mention getting the stuff in difficulties.
I have never had a drop leak from the Mauget system if done properly. Where do you come up with this stuff?
