Water pumping LUV corresponds more closely to BPEL but even more so! BPFSL really only stretchs the tunica length wise, not girth wise, therefore the extra “slack” can translate into longer length. This is why most guys get a longer bpfsl than bpel. When you pump, especially water pump, your tunica is stretch not only to its max length wise, but also girth wise. So I personally find that taking LUV out to bpel dimensions corresponds to a fairly high vacuum if you don’t use a gauge, which I don’t use for water pumping.
Thats why I recommend about 1/4” LESS than bpel for length pumping, and about 1/2” less than bpel for girth pumping. I use about 3/4-1 inch less of my bpfsl for girth pumping. BUT these are only recommended starting points, you guys have to find your own ideal based on your tunica elasticity.
What I found is that bpfsl increases does’t always lead to increases of bpel. Water pumping for me caused my bpel to begin to catch up with my bpfsl, or you could say that increases in MAX LUV does correspond to increases in bpel. However, this in TRUE increases in max LUV and not increases due to too high vacuum for too long of a time resulting in edema. Thats not a true increase, rather just fluid making your LUV look longer.
Some guys draw max LUV with water pumping and do very well with that. If you can tolerate that, and you don’t get drops in EQ or a lot of edema, thats ideal because it will be increase both length and girth at the same time. I find that for me to really see girth changes, I need about 30 minutes in the tube. 30 minutes at high vacuum for me will cause tons of edema. So, for me, I do girth pumping at about 1/2 inch less than bpel or about 3/4 inch less than bpfsl.
Length work doesn’t require that much time for me, so I can pull a longer LUV, which translates into a higher vacuum, but I can use shorter sets to get the job done.
Water pumping generates tremendous pull in both length and girth, and has a much lower bad effect on the skin and blood vessels. You really need to give it a go for about 2 weeks and judge for yourself. IF you have the regular male-female coupling on your cylinder, you should be able to disconnect and it seals off, so you don’t need expensive equipment, just draw to the proper LUV and then disconnect it. Reconnect to either draw additional water out or to release the vacuum.
