American Standard Maybrook 0.125 – 1.0 gpf (0.47 – 3.8 Lpf) Top Spud Urinal With EverClean - AMS-6581001EC

The Maybrook top spud urinal has a 3/4 inch (19 mm) inlet spud, which is the standard commercial flush valve connection. So any 3/4 inch top spud flush valve, manual or sensor, will land on it. The valve is not included; the Maybrook ships as a fixture only with a wall hanger.

Anything from 0.125 gpf up to 1.0 gpf (0.47 to 3.8 Lpf) works. It's a High Efficiency Urinal rated across that whole range, so a pint valve, a 0.5 gpf valve, or a 1.0 gpf valve all flush it properly. That range is what lets one fixture cover a building where some restrooms are on low-flow retrofit valves and others still run the older 1.0 gpf hardware.

The outlet is an outlet spud with a 1-1/2 inch (38 mm) tubing tailpiece, so it drops into 1-1/2 inch tubular waste. You still need a trap and the wall carrier arm or waste fitting behind it; the urinal ships as a fixture only. An integral strainer is built into the bowl, so no separate strainer basket is required.

A wall hanger comes with the Maybrook, so the fixture hangs off the hanger fastened into blocking or a carrier in the wall. It's a wall-hung washdown urinal, not a floor-mounted stall unit. Confirm you have solid blocking or a urinal carrier at the height you're setting it, since the hanger only carries the load if what it's screwed into does.

The Maybrook is ordered in white, model 6581001EC.020, so a one-for-one replacement in a row of white china fixtures matches. What decides whether it drops in is the plumbing, not the color: it needs a top spud opening (the valve comes down from above into a 3/4 inch inlet), and a 1-1/2 inch tubular waste connection. If the existing fixture is a back spud or wall outlet model, the rough-in won't line up.

Fixture only. The Maybrook comes with the wall hanger and nothing else, so plan on a 3/4 inch top spud flush valve, the spud coupling and gasket, a 1-1/2 inch trap and waste connection, mounting hardware into your blocking or carrier, and the supply stop. Contractors bidding this should price the valve separately, since sensor valves and manual valves are a real cost difference on a multi-fixture job.

The Maybrook is a flushing rim washdown urinal, rated commercial. Washdown means the flush sheets water down the bowl walls rather than pulling a siphon, which is what makes it work reliably at flush volumes as low as 0.125 gpf. Siphon jet models flush with more force and more water and are generally spec'd where noise and heavier soil load matter more than water use. If you're on a water-conservation spec or a LEED-driven project, the washdown HEU is the type that hits the low flush numbers.

EverClean is an antimicrobial surface fired into the china that inhibits the growth of stain and odor causing bacteria, mold and mildew on the surface. It cuts down on the odor problem that low-flow urinals are known for, but it isn't a substitute for cleaning. In a high-traffic building it mainly buys you a fixture that stays presentable between cleaning rounds.
