The electric heads (marine toilets) in the boat had a serious (and disgusting) design flaw. Tony wrote them this email:
I have three 58500-0012 electric toilets (foot switch) installed in my boat. Two of them have a tendency (not to put too fine a point on it) to splatter macerated shit up and out of the bowl. This is an undesirable feature in a marine head. As there are no obviously adjustable parts, I am at a loss. What would you suggest?
