Caroma celebrates Earth Month with deals on toilets and sinks.

Caroma  is offering its “One Flush Makes a Difference” promotion in honor of Earth Month again this year over a span of five months in response to the success of last year’s promotion.

Through June 30, 2011, North American customers (Canada exempt) can  to receive a coupon for 50% off the list price of select Caroma toilets or sinks at participating retail locations.

Caroma dual-flush toilets surpass both the U.S. federal requirement of no more than 1.6 gallons of water per flush (gpf) for new toilets and the North American high-efficiency toilet (HET) standard of 1.28 gpf.

Customers can learn the benefits of installing a high efficiency toilet through Caroma’s free, downloadable water saving and conservation calculating files
