Had a great time on the river (6 Days), but at the end of the trip, when I was preparing to dump the sewage holding tank. I developed problems with the TDX-S. The macerator motor would not shut off. The macerator should only run through a 20 minute cycle and then shut down. The manual says, if this occurs, replace the control module. I am not certain, but I believe this is original equipment (pretty old). I have never liked this system, I just don't feel right dumping sewage into the river, even though it's legal in some area's.

My question's are: Has anyone had this issue, and worked it out without replacing the control module? Has anyone with this system removed the tdx holding tank and replaced it with a standard holding tank?

This is a Mansfield TDX-S. Out of business, out of service.

Any suggestions would be helpful. Thanks, Rich
