Push Pull Shower Valve also off in middle position

You need to pull and replace the cartridge on your shower valve most likely. It varies by Make and Model, but generally, remove the handle, remove any sleeve around the center spine, remove the round trim plate, close the service stops, remove the retaining clip or ring, and pull the cartridge straight out of the valve body by pulling on the spline... or get a cartridge puller. Then take your cartridge to the store and get a new one. Flush the valve body by slightly opening both service stops and then install the new cartridge and reverse the process.
Generally this problem occurs when sediment has torn part of the sealing o ring on the cartridge. If you send me the make/model and/or a picture I will give you the specific instructions

SOURCE: Can't get the cartridge out

You have a common problem with Moen cartridges. 1st if the valve is plastic these instructions may not help you, they are for brass valves. If your not afraid to spend a little money you can go to the local hardware store and ask for a Moen cartridge puller. They usually cost between $15-$100 for the good one. Get the one that looks like a tee. (see picture)

1. First turn off the water to the valve.
   
2. Screw the tool to the valve where the handle would connect to.
3. Align the slots on the tool to the slots on the valve.
4. Turn the valve 360 degrees several times.
5. Pull the valve gently and firmly towards slowly increasing the pressure.
   

• At this point the valve will come out and your done.

• If just the center portion will comes out heres what you do.

1. Remove the center portion of the valve from your tool.
   
2. You will notice at the end of the tool handle is a brass ring.
3. Slide ring down to button and depress button until it is held in place with ring.
   
4. Slide this part of the tool with ring into the valve. (ring will not go in valve)
   
5. Insert this into the valve all the way you can until you hear a click.
6. Turn and gently pull until valve comes out.

• Note: if both of these fail you need to change the valve.
  

SOURCE: WATER DELIVERED FROM SHOWER HEAD NOT HOT ENOUGH

I think some shower valves have a safety setting to prevent burning. maybe you could adjust that to be hotter.

SOURCE: a single handle delta shower control lets water

Make sure the drip is continuous because the shower head will drip for a few minutes until it empties out. Replace the cartridge or washer kit if it keeps dripping.

Probably need to remove and replace the cartridge. Often sediment will tear part of the o-ring or seal on the cartridge and cause this problem...
varies by model, but generally, remove the cap on the knob, unscrew the knob, remove the keyed sleeve, remove the round trim plate & shut off the service stops (verify they are fully closed by pulling out on the valve stem) next remove the retaining clip (needle nose and be gentle) that holds the cartridge in place, then pull the cartridge straight out with vice grips or similar (or get a puller). clean the cartridge, flush out the valve body by slightly opening both service stops, reinstall cartridge and clip, open service stops and see if it still leaks. if it does, take your cartridge to the store (any reasonable HW or plumbing store should have a replacement) and get a new one. then reverse the process to reinstall.
If you send me the model I'll get you more specific instrucitons and pictures...
