(...) It actually pumps the water. A large part of the design problem was getting the system to pump an amount of water that wasn't too much and wasn't too little. I'd have to say that the final result was a triumph of trial and error:-) JOHN (20 years ago, 19-Apr-04, to lugnet.trains, lugnet.town, lugnet.technic, FTX)
