"P" Valves

[JoelW]

Balanced valves have a one-way valve on them that equalizes the pressure in the tubing to the pressure in the suit, which is the same as the water pressure,or real close. Both types have a one-way valve right above the outlet. In both cases the one-way valve at the outlet has to be opened against the pressure of the water outside the suit. It takes more user force to open the unbalanced version. How much I am not sure since I have never seen or heard of a report on a randomized study of the relative p#ssing strength for individuals in above atmospheric conditions. In short, no pun intended, a balanced version is the equivalent of not having to pee uphill against the water pressure outside the suit. The downside is the that the balanced versions take more room and the direct route out is difficult to set up unless the outlet is near the knee.

I have an EE balanced version.
