A slow SPG is a bad thing?

    Do you use a rubber washer between the syringe and the orifice to maintain vacuum?

    All equipment fails eventually. You can delay it but at some point it will fall. They're dead people all over the world with equipment that worked perfectly right up to the moment it didn't. Plan for it to fail and you'll have a better chance of living to replace it.

    one remark...
    Corroded metal became thinner. Consequently - flexibility became more flex :)
    Corroded Bourdon pipe under high pressure will show bigger values of pressure.
    ... and without pressure can show over zero values.

    About SPG cleaning from flooding: I had idea to clean tube with alcohol 96% inside, but... cappilary effects will not allow to fill all inner volume, and to make good mix of water inside and alcohol...
    But cleaning under vacuum bell looks reasonable. Liquid should boil inside and evaporate
