American Standard Decorum EverClean Urinal System With Manual Piston Flush Valve, 0.125 gpf/0.5 Lpf - AMS-6042453

The Decorum EverClean urinal takes a 3/4 inch (19 mm) inlet spud and has a 2 inch (51 mm) outlet connection. That is the standard commercial top-spud urinal rough-in, so if the existing carrier and waste are piped for 3/4 inch supply and a 2 inch outlet, the piping does not have to change.

It ships as a system: the fixture plus a manual piston-operated flush valve rated at 0.125 gpf / 0.5 Lpf. Wall hangers are included as well. You are ordering one part number instead of matching a bowl to a valve, which is the usual source of mismatched flush volumes on a retrofit.

The Decorum EverClean uses washdown action with a deep sump, which is what makes the 0.125 gallon flush carry waste and also cuts splash-out at the fixture. For heavy-use restrooms the practical concern with pint urinals is drain line carry, so it wants a properly sloped 2 inch waste run rather than a long flat branch.

This one is manual: a piston flush valve with a non-hold-open handle that shuts off automatically, so no power, no batteries, no sensor to fail or get vandalized. That suits schools, stadiums, and MRO settings where the maintenance burden matters more than touchless operation. If your spec calls for hands-free flushing, you need a sensor-operated urinal system instead, not this model.

The valve uses American Standard's DynaClean self-cleaning wiper spring. An integral wiper spring scrapes the refill orifice on every flush, which is the orifice that clogs with grit and scale and causes a valve to run on. That is the mechanism doing the work here, and it is why this valve is specified on fleets of urinals where run-on is the recurring service ticket.

EverClean is a permanent surface treatment fired into the china, not a coating that wears off with cleaning. It inhibits growth of the bacteria, mold, and mildew that cause stains and odor on the fixture surface. It works on the surface only, so it does not replace trap maintenance or cleaning the drain, but it does slow the staining that makes low-flow urinals look dirty between services.

White only, sold under part number 6042453.02. If you are standardizing a restroom group, white china matches the bulk of commercial water closets and lavatories already installed, so it drops into an existing fixture set without a color mismatch.

The Decorum is the compact fixture in American Standard's washdown line, which is why it gets specified where fixture spacing is tight or a partition sits close. Wall hangers are included for the mounting, but the carrier and blocking behind the wall still have to suit the fixture, so confirm the wall backing before you set the rough-in.
