P-Valves: To Pee or Not to Pee Underwater

When we talk about using P-valves to urinate while diving in drysuits, safety is more important than comfort (although urinating without getting wet and cold underwater is certainly as comfortable as it gets during a dive). The most important thing is that P-valves allow divers to stay hydrated, which, as every diver knows, is essential for dive safety. Given dehydration significantly increases the risk of severe DCS, P-valves are about more than just comfort. They are an essential safety tool for all drysuit divers.
