Franke
Identify
The Franke mixer cartridge is a 133.0069.213. Measure diameter with vernier — Franke used two body sizes on similar-looking taps.
Fit
Isolate under sink. Pop the hot/cold badge, undo the grub screw. Lift lever. Undo dome nut. Withdraw old cartridge. Fit new, aligning the spline at 12 o'clock so hot pulls back-left.
Test
Turn on slowly. Cycle full hot / full cold three times to seat the ceramic discs.
Frequently asked questions
- OEM or compatible?
- Franke originals last twice as long in hard water. Compatibles OK for tenanted properties.
- Do I need silicone grease?
- Yes — silicone grease on the O-rings, never petroleum jelly (perishes EPDM).
