Has anyone noticed a water tank problem I have encountered on my 1987 E34? (Could also occur for other similar models.) Water somehow was getting from one tank to the other, but not consistantly. Just when I thought an unused tank should be full, it was not. At other times is was. I think I have found the problem. The overflow hoses from the separate port and starboard tanks are connected to a single overflow spigot at the sink. The connection is low near the bilge. Therefore when the boat heels water goes from one tank to the other. If I am motering the flow never occurs. I am changing the connection to be high up near the spigot. Hopefully this will fix it.
