Hi, I have a concealed shower mixer. The diverter valve is leaking. I was trying to take out the valve cartridge. But I can't see how I can remove it. The stem is 30 mm long. The base flange (?) is 40mm in diameter. its outside has a thread. There is no grab screw on the outside of the flange holding the flow valve cartridge. Could anyone give me some suggestion about how to take it off? Is the base a flange screwed on the mixer body, or it is part of the body? Thank you.
I didn't. Someone suggested releasing the spring clip at the base and middle stem can be taken out. But I am not sure how the o-ring can be sealed back. Still looking for information to confirm this.
