About the American Standard 4385A.137.020

Complete the revolutionary technology that is entering into your toilet with the American Standard 4385A.137.020 Yorkville toilet tank. This tank incorporates the VorMax flushing technology where it cleans better than other types of flushing systems by using 70% of water to rinse the bowl and the other 30% to start the siphon and remove the waste, making the toilet cleaner and easier to maintain with just a single flush. Also, the Vormax flushing system creates 50% less noise, eliminating the annoying sounds that came from flushing. Despite all these features mentioned, it only uses 1.28 gallons per flush, making it truly an efficient addition to your toilet.

Made of Vitreous China construction, this toilet tank is compatible to use with the American Standard 3359A101 elongated bowl and is sold separately. It also includes a chrome trip lever and has met all applicable drain line carry requirements.
