GROHE45887000 Ceramic Headpart 3/4"

Q: My hot water is leaking. On the side of the cartridge, written as "A (or triangle) 98 04 R 90". Can't find product number. Where to measure for 3/4"

I removed the cartridge and measured it. It clearly was not 1/2", but did measure at 3/4". The reason for the leak is the rubber gasket/washer at the end that is worn.

Q: What are the dimensions of cartridge?

The cartridge is designed to fit in a 3/4 inch piped volume control or a 3/4 inch roman tub faucet.it is 2-3/8" long, 1" diameter at the threads into the valve body.'

Q: Old cartridge wouldn't budge using 17mm socket turning counter-clockwise. Didn't want to force it. Any suggestions for removing the stuck one?

I had the exact same problem. I put the entire faucet on the bench vise. Clamped the old cartridge in the teeth and twisted the whole faucet around till it broke free. (Have a wall mounted faucet)

Q: I ordered unit on amazon. It was too short and looks like it needs an extended control arm. How do I get the correct part number and order part?

Not sure I have the answer, but I have a bunch of these things in my plumbing and several of them (like in my shower--thalia handles) seem too short, but the extra length is supplied by the Grohe faucet handle. Exactly what kind of faucet are you replacing the cartridge on? I think Grohe makes only one cartridge length (but I could be mistaken).
