*Most* manufacturers recommend getting your equipment serviced once a year. Some equipment manufacturers have a "replacement parts warranty for life" & for that warranty to be valid, you must be the original owner & the equipment must be serviced once a year. Usually things that wear with time are replaced, like valve seats & O-rings. Can you get by with not servicing it once a year? I would say, Yes, that is a possibility, but the longer the equipment goes without service, the more you are playing with fire for a malfunction. Would I recommend it? I personally go with the manufacturer's suggestion.
