Um, isn't this against the rules for an untrained Brand-X service person to service Brand-X equipment? Haven't I seen gazillions of posts about "How do I become a Brand-X repair tech?" on this board? Who will be responsible for the gear you service for the LDS if someone gets hurt using this equipment? I don't think this LDS owner knows anything about the law either.
I guess I should have elaborated on that more, but didnt feel the need. Since you brought it up, I will do so now. When they have gotten backed up a few times, I disconnected and tagged all the hoses from the first stages, disassembled and labeled all of the first stage components and set them up to soak. The owner who is certified in the repair of the brands he services does the final cleaning, re-assembly and testing of the regulators. The only equipment that I have been responsible for re-assembling is my own, and I take full responsibility for the functioning of it.
