This cartridge is for a Grohe 3/4" volume control. I bought about five of them. The one operating the main shower valve in the master shower was a problem. It stuck and wouldn't easily turn completely off. Then all of the sudden it worked. Great, now I don't have to call the plumber back!. Charles Dorfman. Kansas City. Wed Oct 22 2025

Be sure to keep your Grohe products in their best condition by accompanying them with the proper hardware and purchasing replacement parts when necessary.

Very supportive team here. I'm no plumber and mis-measured and ordered the wrong size. They respectfully and efficiently made the switch for me and expedited the right size back to me. Not only the people, but their ordering and customer support system is first rate!. Randy, Non-plumber. Minnesota. Sun Jan 24 2021
