The folks at chicagofaucetshoppe.com are awesome! We’ve been trying to find replacement cartridges for years. No one could seem to identify or find them. We sent some pictures and measurements and voila, they have them. Many thanks!

Great product knowledge on KWC parts. These folks meet their commitments - even with longer backordered items - no price increases asked for. I'll be buying from them again for all our KWC needs.
