OMS p-valve help

[IowaCaveDiver]

That's right, I'm asking for you guys to help me with my P valve . Take a look at the photo, this is a small fitting on the inside of the OMS P valve which was leaking on my last dive and I have removed it today and replaced with a high pressure port plug from a regulator. Any ideas if you can get Replacements of just this little part? I'm assuming this is what allows the valve be balanced compared to an unbalanced valve? I figure to avoid any potential discomfort I will ensure the valve is "primed" prior to the dive.

try cleaning it in a sonic machine and see if its OK again. looks like it could use a bit of cleaning

I dont know how the OMS valves work but on the Halcyon ones there is a rubber duck bill one way piece below that set screw that has failed with me. I just did like you did and plugged it with a regular set screw so that now it is an unbalanced valve.

My light Monkey duck Bill failed new, I just pulled and put a reg port plug in. They offered a free replacement, I didn't bother and have just been diving it unbalanced without issue for a year and a half now.

Just got done diving it as you guys described... I don't see any reason to mess with it at this point... Worked great today!

If you decide to try to source the original part try Randy at Piranha Dive Manufacturing. He and I designed that valve while we worked at OMS in about 2000-2001. I used to build them in the factory for stock.

Hopefully you can explain this... What is the true benefit if a balanced p valve vs a non-balanced valve?

Think about the refreshing effects of ice diving in some colder climates.

Not much really. If you are diligent enough to charge your tubing prior to descent, the difference is nil and as you've found out, balanced valves have a weak spot that needs regular service not to screw up.

I like the unbalanced valve. No maintenance other that making sure the hose is clean. I use a mixture of denatured alcohol and hydrogen peroxide. I do a 50/50 mix and squirt 5cc from a syringe in the tube after diving. This has worked for me for 3 years now without any trouble.
