This is probeble old hat, but I am getting bliund reading through.
I replaced both taps in the tub/shower due to leakage, about 1 year ago. Nio problems.
The noticed showere lacked force or flow, now, faucet works, shower does not.
Am I wrong in assuming shower control valve needs replacing?
The temp taps were both pretty corroded due to build up, so I opted just to replace units, not just gaskets.
Also, last time I seem to remember some specialized tools. Since then, the Grinh paid me a visit and stole my car and motocycle tool set. I found one 45 degree angle tool he missed, that looks like ieither end fits into a socket, except the ends are graduated.
Any tool I am just going to need for this?
Thanks,
And if anyone sees the Grinch, please paint target on same and turn loose in street. He will be throwing away brake pads, cables, sparkplugs, etc tht are of no use to anyone other than a fellow BMW motorcycle owner.

Let me go from my original posting.
I am pretty convinced it is the valve that changes the flow from faucet to shower, the diverter. Most of what I have researched o DIY leads me to that conclusion.
However, before tearing things up, I stopped. I had removed the plastic cap, then took out the screw holding the handle itself.
The handle does not want to come off.
Would a little steady back pressure on the handle work to help getting it loose? I have a small crowbar used when taking out wood tack on rugs.
I do not see anything else holding it. It looks like the hot/cold controls whch I already disassembled, and I do not get the impression the handle is threaded.
Thanks

 

There is a tool known as a "faucet handle puller" specifically designed to remove stubborn faucet handles like yours.It is available at most hardware stores.

I believe what has happened is that the washer on the other end of your diverter has likely come loose and is somehow stuck in place blocking flow to the shower.Either that or there is so much wear on the diverter that it just spins when you turn it.

When you get the diverter out look for a washer and also examine it for damage.It is possible the washer may stay inside the faucet and also that the washer has come loose due to damage to the diverter.You won't know until you get the diverter out.

 

It will be tomorrow before I can get that tool. Will update when finsihed, or other glitch

I finally got around to getting the handle puller, and took the handle off. Then I took the nut off with the hollow tube, which allowed me access to a shaft which I assume is the valve itself. (stem?) However, this peice does not seem to want to unscrew. I did not want to put any great pressure behind this for fear I might damage something.
Suggestions?
In advance, thanks

Stems are held in place by one or more outer nuts which must be removed in order to screw the stem itself out.The nut or nuts (sometimes simply hex shaped sections of the stem) will be recessed behind the wall and require a deep socket to remove them.There are many sizes and many are not what you'd have in a tool box.You can get a "plumbers socket set" for around ten dollars to do this job.While at it you might want to remove the hot and cold stems and check the washers on them as well.

 

The hardware store sold me a "tool" that looks like a sparkplug socket. It fits, however I am exerting a tremendous amount of force on the pry bar (screwdriver) to no avail.
I can probably find a longer and thicker "pry bar," but I am always hesitant to using force, for concern I will damage something.
Is there any problem with the pry bar idea, or does someone know of a better way?
Thanks,
