LaVac Caution

Last year, our LeVac began exhibiting strange behavior.

Suddenly after years of service, after doing #2 and pumping, the material within would explode inside the bowl. As you can imagine, this is quite unpleasant to clean for the next person who discovers it. Somehow, this always turned out to be me. I thought it was because something that one of the crew had either attempted to flush or that they were operating the head improperly. This happened when both flushing to sea and to the empty holding tank. Unfortunately, we were on a multiday offshore regatta at the time.

Months after avoiding the job, I eventually broke down the Henderson / Whale pump. To my surprise, the valves, particularly the outlet check valve was in a very questionable state. One valve kit later, all was well again. I think I will add an extra valve repair kit to the list of essential spares.

So, if your LeVac starts to explode, check the valves first before pointing fingers.
