The Delta Faucet Co RP32104 is a cartridge assembly designed for Monitor 17 Series tub and shower valve systems. It maintains balanced pressure between hot and cold water supplies, protecting against sudden temperature swings caused by pressure fluctuations elsewhere in the system. The assembly includes a rotational limit stop, which allows the installer to set a maximum hot-water rotation point as a scald-prevention measure. This part is installed by licensed plumbers and experienced service technicians during valve rebuilds or performance restoration work on existing Monitor 17 installations.
This cartridge assembly is suited for residential tub and shower applications where a Monitor 17 Series pressure-balancing valve is already in place. It is a direct replacement component used when the existing cartridge shows wear, leaks, or fails to hold balanced pressure. Installation typically occurs during a shower valve service call or as part of a bathroom fixture repair or upgrade project. Sold in a package quantity of 3 units per UoM.
Designed for use with Delta Monitor 17 Series tub and shower valves as stated by the manufacturer.
Installation should be performed by a licensed plumber. Shut off water supply to the valve before beginning disassembly, and relieve any remaining pressure in the line. Follow local plumbing codes, including applicable IPC requirements, when servicing shower valve components. Do not force the cartridge into position; confirm correct orientation before seating to avoid damage to the valve body.
