Now unscrew the bonnet nut and pull out the stem unit assembly. This will expose the seats and springs. Remove them and check the opening for crud or blockage. Now, while the valve is open) turn on the hot water and flush out the supply line. You should have a full stream. If so, reassemble. If not then the blockage is further downstream and you may have to call in outside help. Good luck, Tom

I seem to have the same problem in one of my showers! I presumed that it was due to hard water crud but as I was unable to get to the guts of the plumbing, I have been not been able to do anything with it! I don't really know what brand of shower valve or shower head it is! I am attaching a picture of the valve here. Could some one identify the manufacturer? Here is the head. Please note that I have not been able to get behind the wall.

Any help will be appreciated. Thanks bagchip

Is this it?
Remove the handle: How?
rest of the parts SPIN off counterclockwise: Shall try!
Thanks a a lot!

Whatever is in the very center of the handle...is it a chrome cap (?)...that needs to be pried up using a little flat screwdriver and that should reveal the screw holding the handle in place. --- Done that. I shall turn the screw counterclockwise and see how I do and let you know.

Thanks MARK

I shall turned the screw counterclockwise and the valve handle came off! Those Germans, smart s of g's! Now the scene is as this. Iguess, I do the following: Turn the H&C water off in the basement. What next? Do I just play with it, til I figure it out?
You know MARK, you are a good teacher!

That picture is real fuzzy so can't be 100% sure, but yeah, turn off the hot/cold water to the valve and then discharge the pressure by opening the valve. Then you can try to remove the chrome, etc. by loosening all counterclockwise.

There may also be a clip involved.

If you can clear up the pic. I may be able to tell you more....

Yes, that is a bad picture! Here is a better one MARK.

I have also been busy. I contacted GROHE. Evan Thomas, in their SC identified the valve controller and sent me a cleaning procedure. Evan was very helpful. He also told me that I would need a 24mm socket to take the nut out. So, I got a metric set from Harbor.
Mark also told me to pry off the various rings, washers, control rings etc. and then take the bolt off. Except all these seems to be stuck so strongly that I have not been able to take them off yet. The temperature controlling ring seems to go around but I have not been able to pry it forward with a screw driver.

Do you think that drops warm vinegar solution could be used to dissolve the calcium?

Looks like you remove the handle by removing the nut in the center.
