American Standard Built-In Pressure Balance Diverter - AMS-51120

Two finishes: chrome, part number 051120-0020A, and brushed nickel, part number 051120-2950A. Pick the one that matches the rest of the trim on the valve you are servicing, since the diverter face is visible once installed.

The diverter is the component that routes water between outlets, such as tub spout to showerhead, inside a built-in pressure balance valve body. The pressure balance part of the valve keeps temperature steady when other fixtures draw water. The 51120 is the diverter portion sold as a repair part, not a complete valve body, so it is what you order when the diverter has failed and the rough-in stays in the wall.

It is a genuine American Standard repair part, the kind plumbers use to repair American Standard fixtures rather than a generic substitute. For a property manager standardizing on American Standard valves across a building, that keeps the replacement identical to what came out.

No. This is a repair part meant to go into an existing American Standard valve, and American Standard lists it as easy to install. The rough-in valve body and supply connections stay where they are; you are replacing the diverter assembly through the trim opening.

You can order either finish independently, chrome 051120-0020A or brushed nickel 051120-2950A, but the diverter is visible at the trim so a mismatch shows. On a fleet of units where the trim is already chrome, order chrome and keep the openings consistent.
