Jeanneau SO40 Holding Tank Replacement

Karl Lahm provides an excellent step by step guide

 

By any measure, the 40 liter capacity of the sewage holding tank provided with the 2000 Sun Odyssey 40 is grossly inadequate, especially for sailors on inland waters and those who do not venture sufficiently far offshore to empty the tank at short intervals. Its small size encourages ignorance of environmental regulations rather than fostering respect for them. And so I set out to increase the tank’s size significantly, and thereby facilitate “domestic tranquility” aboard.
