Mira 1836.170 Resolves Shower Problems

Should the Mira Atom or Coda shower drip from one shower head while the other is in use, 1836.170 flow and diverter cartridge is what it takes to get the shower back to normal.

About the Mira Spare Part: 1836.170 is a push-fit flow diverter cartridge. It is a 35mm replacement cartridge with a 20 teeth spindle. At 3 Bar, the cartridge can handle at least 21 litres per minute (5.5 gallons per minute) water flow rate.

Common Problems: The most common causes of problems regarding the flow diverter are hard water sediments and/or wear and tear. Limescale can collect on the brass spindle which results in a stiff to turn handle. Wear and tear can affect the entire Mira 1836.170 from the spline to the bottom seal giving rise to leaks.

Fitting: Changing the Mira 1836.170 can be simple. Turn off the hot and cold water supply to the shower. Then remove the handle, the retaining nut, and take out and replace the diverter cartridge.
