Much of the discussion has been about the hose quality, but equally the issue is having a discharge system that allow waste to accumulate and sit in the hose. It seems to me that is a poor design. I've used the cheap
WM hose without such smell, but I placed the tank not far above waterline with a steep, continually downhill discharge to the through hull
. Not only does this prevent sewage from sanding
but also allows sea water to flush the hose. Also no pump or pumping required to empty the tank.
