American Standard Washbrook 0.125 – 1.0 gpf (0.47 – 3.8 Lpf) Top Spud Urinal With EverClean - AMS-6590001EC

The Washbrook is a High Efficiency Urinal that operates anywhere in the 0.125 gpf to 1.0 gpf range (0.47 to 3.8 Lpf), so a 0.5 gpf valve is well inside its operating band. That wide range is what lets one fixture serve both a low-flow retrofit and a heavier-traffic restroom running closer to a gallon. The urinal ships as fixture only, so the flush valve is a separate order.

Top spud inlet at 3/4 inch (19 mm) and a 2 inch (51 mm) threaded outlet connection at the back. The supply comes in above the fixture, so the flush valve and its supply stub have to be roughed in overhead, not behind or below the bowl. Two wall hangers come with the fixture, plus a chrome plated non-metallic strainer for the outlet.

The 6590001EC is fixture only. You supply the flush valve (any model working in the 0.125 to 1.0 gpf range), the wall carrier or support if your construction needs one, and the outlet gasket and hardware for the 2 inch threaded outlet. What does come in the box is two wall hangers and a chrome plated non-metallic strainer. Plan the valve as a separate line on the order; that is the most common omission on a urinal takeoff.

Yes, provided the existing rough-in is top spud with a 3/4 inch supply and a 2 inch outlet. The fixture accepts flush volumes from 0.125 gpf all the way up to 1.0 gpf, so an existing 1.0 gpf valve can stay in service, or you can drop to a low-flow valve later without swapping the fixture again. Verify the existing outlet centerline and rim height against the 14 inch rim projection before you demo the old bowl.

Top spud, like the Washbrook 6590001EC, brings the supply in above the fixture and pairs with an exposed or concealed flush valve mounted on the wall above. That is the usual commercial arrangement because the valve is reachable for service without pulling the fixture, and it is what most existing commercial rough-ins are already piped for. Bottom or back spud fixtures hide the supply but commit you to a different rough-in height. If you are replacing an existing urinal, match the spud location you already have rather than re-piping the wall.

It is built for commercial duty and carries the EverClean antimicrobial surface, which inhibits growth of the bacteria, mold and mildew that cause staining and odor on the fixture surface. That plus the flushing rim and washdown action is aimed squarely at restrooms that get cleaned on a schedule rather than after every use. Extended sides give a measure of privacy where urinals are set close together without partitions.

White is the only finish, ordered as MPN 6590001EC.020. For a property manager standardizing restrooms across a portfolio, that simplifies things: every Washbrook top spud unit you add will match the ones already installed.
