Dumping a little valve oil quite often through an ALREADY CLEAN () mouthpipe is also (in my belief) an excellent preventative of dezinctification ("red rot"), because it leaves a slick petroleum film on the mouthpipe's interior to which lime/calcium cannot easily adhere.

To the original inquiry: Do not base your judgement of the action of all rotary valves nor the playability of rotary valve tubas in general on the one currently at your disposal. You will be disqualifying a lot of nice models of tubas.
