Ideal Standard B961902NU Multiport Small Cartridge

Summary

Ideal Standard B961902NU Small Multiport Single Lever Cartridge for Taps and Shower Valves

The Ideal Standard B961902NU is a small multiport single-lever ceramic cartridge used to control water flow and blend hot and cold water in selected Ideal Standard, Sottini, Trevi and Armitage Shanks taps and manual shower valves.

B961902NU is supplied as the current replacement for the former A951970NU11 small multiport cartridge. The replacement has a different body appearance and dimensions from the discontinued cartridge, so identify the part by its code, port arrangement, locating pin, seals and handle connection rather than diameter alone.

Technical Details

Common Failure Symptoms

A worn or damaged B961902NU cartridge can cause water to continue dripping from the shower head or tap spout when the control is turned off. Other symptoms can include a stiff lever, poor flow control, difficulty shutting off the water fully or difficulty obtaining the intended mixed-water temperature.

Before Ordering Notes

Compare the existing cartridge code, overall body shape, port arrangement, locating pin position, O-ring positions and handle connection before ordering. The model fitment below applies to versions originally fitted with A951970NU11 because some mixer model codes were produced with different cartridges during later production periods.
