Both Phil Horton & I had to replace the flexible hose in our kitchen faucets due to restriction. The Grohe part # is 46 092 000. Both Phil & I purchased replacements at Amazon, but they are available elsewhere. Before you buy any parts for your Grohe faucets, call Grohe---the faucets manufactured from 1997 to present have a lifetime warranty. Grohe customer service is very good and if you can convince them that a part failed to perform as designed they will send you the part free.
