5 of 5 Super amount of KWC parts January 17, 2023
Reviewer: Jack Deshefy from Howell, NJ United States  
After trying to find a back flow preventer for my Domo faucet I came across Chicago and was pleasantly surprised at how many high end faucet parts they carried. Ordering was simple and shipping was fairly quick. I'm very happy!

5 of 5 KWC Z.534.034 Replacement June 25, 2021
Reviewer: Anonymous Person from Cape Elizabeth, ME United States  
My original backflow preventor was 2006 vintage-chrome played. The replacement is not, but no matter, it lives under the sink. The replacement solved  the restricted flow issue I had following total disintegration of a shut off valve rubber washer.  Of note is, I need a threaded coupling from the original pull-out hose the insert the replacement - easy.   It’s nice to know I can trust a mail Order company that isn’t Amazon.

5 of 5 Kitchen undersink filter also December 11, 2020
Reviewer: Donald Sigman from Denver , CO United States  
This is a back flow preventer and a filter also.  When filter is dirty or at worst clogged it very much reduces flow into and from the faucet. The filter is located in the connection under the sink. So it is easy to NOT KNOW it is there! Don't think you have a problem in the faucet itself or the water pipes..it is in the easily removed filter/back floe preventer!!
