Hi,
Can anyone please tell me how to change a cartridge in a Grohe AStomatic 2000 shower
Water is leaking from the handle and I was told to get a spare part for it. I just bought a cartridge and have no idea how to change them. I cannot afford a plumber as they are very expensive. Also, do I have to drain all the water off from my tank before I do this job.
Thanks for your help and advsie.
