I-TEAM: Company Suing State For Right To Use AAVs

(WCCO) Earlier this year, the WCCO-TV I-TEAM revealed a law that made water-saving flushless urinals illegal in Minnesota.

The law was overturned, but the same legislation banned what are called air admittance valves.

The valves keep sewer gas from escaping without having to build regular pipe systems through roofs. Plumbers have fought against them because they'd lose work.

Now the state of Minnesota is being sued over them. Studor Incorporated makes the valves and in court papers said the Minnesota law is arbitrary and violates the company's right to do commerce.

The company has won its case in other places and the valves are now used in 30 states.
