The Delta R10000-UNWS is the MultiChoice Universal rough-in valve with integral service stops. The built-in stops let a plumber shut off water directly at the valve body during cartridge service or trim upgrades, without hunting for supply shutoffs elsewhere in the wall. It is otherwise identical to the R10000-UNBX — accepting all Delta 13, 14, 17, and 17T trim kits and cartridges, supporting IPS, PEX, and sweat connections, and operating from 30–100 PSI. Strongly recommended for new construction and remodels where easy serviceability is a priority.
Why choose the UNWS over the UNBX?
The UNWS has integral service stops that let you shut off flow right at the valve body. This is extremely convenient when swapping cartridges or upgrading trim kits, because you do not need to locate and close the supply shutoffs elsewhere in the house. Plumbers generally prefer valves with stops. The UNBX is slightly less expensive and still acceptable in installations where accessible supply shutoffs are nearby.
Is the R10000-UNWS compatible with the same trim kits as the R10000-UNBX?
Yes — both valves are identical in trim compatibility. The UNWS accepts all Delta Monitor 13, 14, 17, and 17T series trim kits, including every collection Delta offers: Trinsic, Lahara, Cassidy, Dryden, Vero, Stryke, Victorian, Addison, Linden, Ara, and Foundations.
