American Standard Yorkville Pressure Assist Back Outlet Elongated EverClean Bowl - AMS-3701001

The Yorkville 3701001 is the bowl only. It's a floor-mounted, back outlet elongated bowl that pairs with a pressure assist tank, and American Standard lists it as compatible with both 1.1 gpf/4.2 Lpf and 1.6 gpf/6.0 Lpf tanks. Budget for the tank, seat, and supply as separate line items. What does ship with the bowl is four color-matched bolt caps and two floor bolts.

No. A back outlet (rear discharge) bowl like the Yorkville 3701001 waste-connects horizontally through the wall behind it, not down through the floor. If your rough-in is a floor flange, you need a floor outlet bowl instead. The Yorkville sits on the floor and is anchored with the two supplied floor bolts, but the waste line has to be in the wall.

The Yorkville 3701001 is a standard 15 inch bowl height, which is the conventional height, not a comfort/right-height bowl. For accessible fixtures where seat height matters, you'll want a taller bowl. The 15 inch figure is the bowl rim; the seat adds to it.

Pressure assist uses the building's water pressure to compress air in a vessel inside the tank, so the flush is a fast, forceful discharge rather than a gravity siphon. In high-traffic restrooms that means fewer double flushes and less clogging, and the Yorkville bowl runs on either a 1.1 gpf or 1.6 gpf pressure assist tank so you can spec for a water-conservation target or for maximum carry. The trade-off is noise, which is why gravity is usually preferred in hotel guest rooms and residential units.

It takes an elongated seat. The Yorkville 3701001 is an elongated bowl, so a round front seat will not cover the opening correctly. The seat is not included with the bowl, so add an elongated commercial seat to the order.

Not directly. The Yorkville 3701001 is floor-mounted and bolts to the slab with the two supplied floor bolts, while a wall-hung fixture hangs off a chair carrier in the wall. The waste connection is similar in that both go out the back, but the support method is different, so a carrier retrofit is a different fixture. Where a back outlet floor-mount is useful is on slab-on-grade construction where you cannot get a drain under the floor.

EverClean is an antimicrobial surface fired into the china that inhibits growth of stain and odor causing bacteria, mold and mildew on the surface. It cuts down how fast a bowl stains and smells between cleanings, which is the reason facilities crews spec it, but it is not a disinfectant and does not replace a cleaning schedule.

White only, ordered as part number 3701001.02. The four bolt caps that ship with it are color-matched to the white china, so nothing extra is needed to finish the base.
