So today I'm going to try pumping for maybe 1-2 hours on a very low preasure, normally I do two sets of 20 minutes with preasure just below 10, the tube is 2" diameter and 9" length, I pack it width wise but not length any advice and tips welcome
11/19/21. I did water pumping today and it felt better the vacuum pumping. I just wish I had my own place so I could do it more then vacuum pumping. I still like both of them. Which gives you more gains??? Anyone knows?
