Moen Ec 44828M-BULK Pressure Balancing Cartridge

Product Description

The MOEN EC #44828M-BULK is a pressure balancing cartridge designed as an OEM-style replacement for single-handle shower and tub-shower valves. Pressure balancing cartridges maintain a set ratio of hot and cold water supply, protecting against sudden temperature shifts when other fixtures draw water elsewhere in the system. This cartridge is sized and ported to drop into existing valve bodies without modification, making it a straightforward service part for licensed plumbers and experienced fixture technicians handling routine valve rebuilds or complaint callbacks.

This cartridge fits residential shower and tub-shower applications where a pressure balancing valve is already installed. It is sourced as a bulk-packaged unit, making it a practical stocking item for plumbing service companies that regularly service single-handle shower valves. The raw title references the MOEN 1222B as the OEM cartridge this part is intended to replace, and the raw description references POSI-TEMP valve compatibility, indicating fitment in that valve family.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician. Shut off the water supply to the valve and relieve line pressure before removing the existing cartridge. Cartridge orientation is critical on pressure balancing valves — confirm alignment tabs are seated correctly before reassembling the handle and trim.
