To P-Valve Or Not To P-Valve: Pros And Cons

Hey divers!

When it comes to wetsuits, there are two types of people: those who pee in their wetsuit and those who lie about it. But with drysuits, it’s not that easy. That’s where the P-valve comes in, a game-changer for divers looking to stay comfortable without compromising their hydration or dive times. Whether you’re considering adding one to your drysuit setup or just curious about what benefits and drawbacks they offer, this post is here to guide you through the ins and outs. So, let’s get into the nitty-gritty of P-valves and find out if one belongs in your drysuit setup.

Understanding P-Valves

A P-valve is a device installed in a drysuit that allows divers to relieve themselves without having to remove their suits. It’s especially handy during long dives, cold water dives, or when you’re just hydrated a bit too well. There are two main types: balanced and unbalanced, with the former being more popular due to its prevention of squeeze during descent.

Advantages Of P-Valves

Comfort and Hydration: With a P-valve, divers no longer have to limit fluid intake before dives, promoting better hydration and comfort.

Extended Dive Times: They allow for longer dives without the discomfort or distraction of needing to go.

Convenience: Especially in cold water, not having to remove a drysuit to relieve yourself is a significant convenience and comfort factor.

Dive Safety: By encouraging proper hydration, P-valves indirectly promote safer diving by reducing the risk of decompression sickness.

Disadvantages Of P-Valves 

Installation and Maintenance: Fitting a P-valve requires modifications to your drysuit and comes with an additional maintenance routine to ensure hygiene and functionality.

Learning Curve: Getting used to using a P-valve can take some time, and the initial setup process might be daunting for some.

Risk of Leaks: If not properly maintained or installed, there’s a risk of leaks, which can lead to an uncomfortable and cold dive. 

Additional Cost: P-valves are an extra expense on top of an already pricey piece of equipment like a drysuit.

Who Should Consider A P-Valve?

The P-valve is an excellent option for:

  • Divers engaging in long technical dives where dehydration can be a concern.
  • Those who dive in cold water regularly and want to avoid the discomfort and risk of removing their drysuit.
  • Divers looking for added comfort and convenience on their dives.

Final Thoughts

While a P-valve might seem like a luxury to some, for avid divers, especially those who engage in longer or colder dives, it’s a significant upgrade in terms of comfort. Considering the pros and cons, it’s clear that the benefits can outweigh the drawbacks for many in the diving community.
