I have been working on my Dometic Sealand 210 for different stuff this Summer and Fall. I had the plastic shaft on the dumping ball valve round out its end and stop actuating the ball; then recently the water valve (with the mushroom cap that is actuated by a cam surface on the pedal) plastic shaft started bending (intermittently) instead of going down and turning on the flush water. What I found in both instances is that Dometic has upgraded these 2 actuator shafts from plastic to brass on the replacement parts.
