As with regulators, some plumbers are more open to these technologies than others. Some might even tell you that certain things cannot be done (because they have not done them before). If that is the case, your options are to either educate the plumber or find another. Have them call our toll-free phone line, (855) 864-5980, for assistance.

For those plumbers who still consider composting toilet systems a funky technology, let them know that the Commonwealth of Massachusetts has included composting systems within its State Plumbing Code and requires that licensed plumbers install plumbing board approved composting toilets just as they do water closets (their term for flush toilets).

If you want your plumbing contractor to bid the installation job competitively, you will probably need a plumbing specification to furnish to each of the bidding companies.
