American Standard Delancey 1.8 gpm/6.8 L/min Shower Trim Kit With Water-Saving 4-Function Showerhead and Lever Handle - AMS-TU052507

The Delancey TU052507 is a trim kit: showerhead, lever handle, escutcheon and the pressure balance cartridge assembly. It is not a complete shower valve on its own, so the in-wall rough-in valve body has to be ordered as a separate line item. On a remodel where a compatible American Standard pressure balance rough-in is already in the wall, the trim goes on without opening the wall. On new construction, budget both parts.

It flows 1.8 gpm (6.8 L/min), which is below the 2.5 gpm federal maximum and matches the 1.8 gpm threshold most water-conservation programs and California/Colorado style flow limits are written around. American Standard puts the saving at 28 percent. For a hotel or multi-family retrofit where the spec says a 1.8 gpm showerhead, this trim answers it without a separate flow restrictor.

It runs a double ceramic pressure balance cartridge with an adjustable hot limit safety stop, so the installer can cap how much hot water can reach the mix and the balancing spool holds outlet temperature steady when someone flushes a toilet or starts a washer elsewhere on the line. That is the pressure balance behavior facilities generally require in scald-sensitive occupancies. It is a pressure balance valve, not a thermostatic one, so it reacts to pressure swings rather than holding a dialed-in setpoint temperature.

Four finishes: Chrome (TU052507.002), Polished Nickel (TU052507.013), Brushed Nickel (TU052507.295) and Brushed Cool Sunrise (TU052507.GN0). The suffix on the model number is the finish code, so if you are standardizing a building on one finish you can order by that suffix across the Delancey line and keep the lavatory and tub fillers matched.

Yes. The Delancey trim's cartridge has back-to-back capability, meaning hot and cold can be reversed at the cartridge rather than repiping. That comes up constantly in back-to-back bathroom layouts in apartments and hotels where the second unit gets mirrored supplies.

No separate check valves are needed. Check valves are integrated into the cartridge to eliminate cross flow, which is what keeps hot from migrating into the cold line and showing up at a nearby cold tap. One less fitting to buy and one less joint in the wall.

Service is a cartridge swap. The mixing valve and balancing spool are combined in a one-piece cartridge, so a maintenance tech pulls the handle and escutcheon, changes the one part, and is done, instead of sorting through a stack of separate components. The ceramic disc mixing surfaces are also unaffected by mineral deposits, which matters in hard water buildings where rubber-seated valves fail early.

The showerhead offers four spray settings selectable at the head, at a 1.8 gpm flow rate across the kit. For a property manager spec'ing guest bathrooms, that gives tenants spray choice without pushing flow above the conservation limit.

The single lever handle runs a Comfort Zone cartridge, which widens the portion of handle travel spent in the usable temperature range instead of burning most of the arc on water that is too cold or too hot. Practically, small handle movements land where you want them. The hot limit stop still caps the top end wherever the installer sets it.
