The plumbing that allows water to be drain is so crucial to the development of sanitary systems and American Sanitary Plumbing Museum reminds you of just that. Created in 1979, Russell Manoog used a collection of toilets and plumbing items his dad Charles had gained over the years.
This museum offers a plumbers point of view on sanitation focused on the engineering and developments that took place to allow the current sanitation system we have today. You can see a collection of not just toilets but things such as wooden pipes used long ago, sinks and tubs, and plumbing trade publications from the 1920s.
If you decide to visit the American Sanitary Plumbing Museum it is located in Watertown, Massachusetts. They are open from Monday to Friday 8AM-5PM.
