I just got a basic gas pressure washer which came with an Annovi Reverberi RMV series pump, which I believe is one of their basic low end units. To my surprise there is no oil plug, and on reading the manual it suggests that no oil change is necessary.
If one were to change the oil, the head has to be pulled and there's a tiny plug where the oil would be filled. It's such a tiny plug, I don't even think one could readily drain the oil out easily. In addition to that, the pump uses a fancy AR branded synthetic oil instead of a simple gear or ND oil.
So what's everyone's thoughts? Should I just leave it as is for it's lifetime? I always thought Annovi Reverberi was supposed to be considered a top tier manufacturer, but this sealed design has me suspicious. My last pump failed when the oil/water seals started to go bad and water would get in the oil. Atleast with an oil plug, one could tell when the water was in the oil. With this design, you almost would never know.
