The rule of thumb is to have your regulator serviced by a certified Service Technician either every year or 100 dives, whichever comes first. The best time to do this is when you get your cylinder is tested.
As well as the annual scuba diving regulator service it is also necessary to wash your regulators in fresh water after every dive. First always replace the dust cap to protect the first stage as soon as the regulator is removed from the dive cylinder. Next, rinse the regulator in clean fresh water. While submersed, move it around a little bit to remove any loose particles that may have stuck on. You also want to turn the flow control knob and Venturi lever to help remove any salt particles trapped on them.
Do not press the purge button on the second stage. This can let water enter the first stage via the second stage. For the same reason, do not wash your regulator under a high-pressure water flow.
Check the mouth piece for damage to the bite tabs and near the cable tie that secures the mouthpiece to the regulator. If damage is found or water is leaking in while you breathe from it, replace the mouthpiece as soon as you can. It is a good idea to carry a spare mouthpiece.
Lastly, rotate the LPI bezel to remove any salt crystals from the internal ball bearings. For safety and hygiene reasons it is also a good idea to own your own regulator.
