Dive Rite

I have a problem... my DiveRite manifold blew a burst disk at 3000psi at 160ft - besides scaring the living daylights out of me and having to abort the dive with emergency procedures, I cant seem to replace the disk
now turns out, whoever the nut job was that put the stuff together at diverite, waaaaayyy over tightned the burst disk assembly and the burst disk plug literaly cut into the disk itself, damaging it.. so it was just a matter of time before it all tore up.. in fact both the valves had the burst disk assemblies that tight, cutting into the disk itself..
PLUS now the damn copper washer thats part of the assembly, (its sits underneath the disk) was to tightened down that it almost fused to the valve and I cant get the damn thing out to replace it.. i tried everything from picks (those denstist kinds) to gently prying to ultrasonic cleaning it for 1 hour... zero luck
SO - my question is.. how on earth to I remove the copper washer so i can replace the burst disk..
or is this factory snafu going to cost me a new valve?
thanks!

All Dive Rite burst disks are 3500 PSI which means the actual burst pressure is 5250 PSI. The seating marks you see on the disk are from the initial air pressure put to the disc when the valve is tested before shipping.
As with any life support equipment burst disks should be replaced when the valve is serviced or anytime the burst plug is removed for any reason. As you know a burst disk is a safety measure to release air upon over pressurization so that the tank itself does not have a catastrophic failure. Typically, burst disks release when tanks are being filled and not underwater. The fact that yours burst underwater is likely due to water in your tank, corrosion or moisture. To prevent this happening again, you'll want to make sure a certified technician inspects your tanks prior to diving.
Your particular manifold is over four years old and since that time we switched to a nylon washer that is much easier to remove. We're happy to remove the copper one - it takes a little elbow grease but can be done. Contact us at service@diverite.com if you'd like us to assist. We'll do a thorough evaluation of the manifold in the process.
