So I've just completed the TDI O2 Service Tech course which certifies you to clean gear for O2 service (nothing unexpected in the course really) including tanks and valves. As the owner of a large number of tanks and valves already (and growing) and as we have to Hyrdro our stuff every single year here, I expect to save a fair whack of $$ doing it myself.
However, on the course they taught us to replace everything in the valve every service - to change the burst disks and the bonnets etc every service. I've noticed however that many of the service kits seem to have these as optional parts. So.. do people really change everything every service or not? Looking at the kit prices it takes the price of a kit from say $15 (cheaper if I sourced the o-rings directly I assume) to say $35 for an all inclusive kit.
Just looking for real-world advice vs theoretical course info
