Description of Grohe 45220200 Control Insert Finish
GROHE StarLight finish for scratch and tarnish-resistant surfaces for a lifetime of beauty. Brand name: GROHE. Model number: 45220200. Country of Origin: United Kingdom.
It fits perfectly (standard size) and works well but is not a Grohe product. The little packet it comes in has 6 or more brand names marked 'compatible' not including Grohe.
It seems that limescale and deposits reduce the water pressure in the faucet over time. This brought him back to full strength. Personally open the tap fully - this is too much. We include only partially. Note. Results may vary. Our house water pressure is currently around 70psi.
