I've encountered a Grohe single handle kitchen sink faucet that has no
visable signs for diassembly. The handle on/off operation is about as stiff
pulling out the proverbial Excaliber, but hot to cold is a breeze. Off/on
is a push from left to right, and cold/hot is front to back. I'd like to
replace the unit, but the customer has some sentimental value attached to
it. Before I ask my local Grohe distributor how this is done, is anyone here
familiar with these and have any suggestions?
