It is possible that you installed a bad valve cartridge, it would not be the first one. It is also possible to over tighten the cartridge retaining nut, rare, but it can happen. In either situation you need to call KWC and ask them to send you a new cartridge asap. They are usually very easy to work with. If you need further assistance please let us know.

Sticking of KWC Suprimo faucet

My bathroom faucet handle (not same brand as yours) was so hard to turn that it pulled the base around with it on the vanity when I jerked it. I used an Allen wrench to take out one of the set screws holding the handle on, put the tiny straw of a WD40 can in the set screw hole, squirted WD40 inside the handle, replaced the setscrew, and worked the handle to and fro a few times to lubricate the inside. No more sticking!

Remove flow restrictor on KWC Faucet

We have a KWC 10.501.012.000 - Systema kitchen faucet and after installation the water pressure was much lower, even after adjusting the faucet's limiter screw to "minimum". We ultimately decided that the reduced flow was unusable and called back the plumber service. They sent out a different guy this time and he knew where to find and how to remove another of the faucet's built-in limiters (it has three, apparently).

I saved the removed water limiter parts. I hope this picture of them can you or anyone else with this same problem remove the limiter and get strong flowing water again...

I have a KWC K24.41.61.000C06 and I live in a drought region. How can I limit the flow on the main faucet?

This faucet is designed to run full open and has no adjustments for lowering the flow. I would put something around the handle to keep the lever from opening completely maybe some pipe insulation or tape. Now you could get into the hose connection where the filter screen is and make a small washer type deal with a small hole in it to restrict the flow.
