I'll be waiting to hear back @Paul Sandhu The Louisiana people told me to let it stay in fresh water in a big drum for a few days. 

In the middle of nowhere.And instead of a composting toilet, think about digging a hole (deep) and putting a couple of 55 gallon drums (with leach line if needed).

Now in addition, Air BnB sets your homes pricing lower for your first year so you can drum up plenty of business and build up those reviews.

Why not put an add on FB marketplace and see if you can drum up some business?

Assuming all the hoses and drain pipes are hooked up properly, there are two likely problem areas.1) On front load washers there is a wide rubber area in front of the drum. 

Your contractor analogy is quite apt: just like a contractor pushing to close a high margin deal, you resort to a fear narrative to drum up business.

@Henry Clark I always go with a 12' wide x 14' tall sectional door (not a drum door).

For example if it's underwater, on the side of a mountain with a 60 degree grade, if there's 100 55 gal drums of PCBs half buried in the ground, it could cost you a lot. 

The old cast iron drum traps are a nightmare to replace in small floor cavities if 2inch PVC traps are the code requirement.Electrical feeds could have been be scabbed in to cover K&T behind the walls & if upgraded it may be ungrounded & many junction boxes could be buried inside ceilings & walls.

@Eric Drum thanks for the answer.
