WORCESTER, Mass. (AP) – Worcester’s toilet museum is moving down the pipes.

After 20 years, the founder of the American Sanitary Plumbing Museum is turning over the collection of porcelain relics to the Plumbing-Heating-Cooling Contractors of Greater Boston.

In March, crews will crate up the museum’s commodes, urinals, claw-foot bathtubs and plumbers tools to be shipped to Watertown, where a new museum should open in the spring. Hugh Kelleher, executive director of the contractors association, says the Smithsonian offered to take the collection, but museum founder Russell Manoog, and his wife, Bettejane, wanted to keep it in New England.

The Manoogs have staffed the museum since 1988. Russell Manoog’s father, who owned a plumbing supply business, started the collection when plumbers would give him old toilets.
