Cheapest option might be to install a new one.

I am looking at installing a holding tank so would also be replacing the manual jabsco unit I have an have been advised against a tcm by shipwright says that they are a cheap Chinese unit. Then after reading Jode5 comments about the jabsco electric they don't sound to good either. I want to keep the chances of something going wrong with the unit to a minimum thus might be somewhere skimping won't pay off. Some might be able to pass on experience with the different brands.
Two dogs, my tmc aint bad at all, not the worlds best, but not the most expensive either. If you want to do a test run prior to a possible purchase

you know where the boat lives, call me and arrange a time.
