Delta R22000 Rough-In Valves Compared: WS, MF, PX, MFWS and PXWS

2 min read
Golzar Home Delta R22000 rough-in valve comparison cover with two MultiChoice valve bodies

All six Delta R22000 models are MultiChoice Universal rough-in bodies with an integrated shower diverter. The right SKU comes down to two choices: how your plumber will connect the pipe, and whether you want built-in service stops. The compatible trim and its cartridges determine the type of shower control and the diverter settings. Delta R22000 technical specification, Rev. F

R22000 vs. R22000-WS

Both use the same universal connection style. WS adds hot and cold service stops so a technician can isolate the shower valve for service. This is especially useful when closing a shared water supply would inconvenience other occupants. Confirm the building's shutoff requirements separately on a condo or multi-unit project.

R22000-MF vs. R22000-PX

MF is Delta's cold-expansion PEX version. PX is its crimp PEX version. Both are nominal ½ inch, so the pipe size alone cannot tell you which one to order. Ask your plumber which joining system is specified. For cold expansion with service stops, order MFWS. For crimp with service stops, order PXWS.

How do you choose the shower trim and diverter?

Match the body with a Delta integrated-diverter trim listed for this rough-in. Monitor 14 and Monitor 17 are pressure-balancing options. Monitor 17 provides separate temperature and volume controls. TempAssure 17T is the thermostatic option. Delta supplies the cartridges with the trim.

A standard three-setting shared diverter is a typical choice for an overhead head and a hand shower. It selects either outlet or runs the pair together. A six-setting shared diverter supports three outlets individually and three two-outlet combinations. Delta also lists non-shared cartridges for configurations that need individual outlet selection only. Follow the port layout for the actual trim and cartridge. Delta installation instructions

What should you confirm before the wall is closed?

Write the full valve SKU and trim SKU on the fixture schedule, count the outlets, and confirm the pipe connection and finished wall thickness. Delta lists up to 1⅛ inches of finished wall thickness for a standard installation and up to 2⅛ inches with the appropriate trim-specific extension kit. For a plan that includes a tub spout, confirm the intended valve and piping arrangement with Delta and your plumber before installing the rough-in.
