Maintenance of the regulators

Last Sunday, we managed to do the second half of the annual maintenance of the regulators.

The regulators were disassembled, ultrasonically cleaned and assembled again. The regulators contain a lot of rubber o-rings that wear off after a while. To prevent leakages, all rubber o-rings were replaced as well. The maintenance was done under the supervision of Mark from ‘DuikeninGroningen’, who learned us a lot about how to tinker around with regulators.
