I HAVE A GROHE SHOWER HEAD THAT HAS WORKED PERFECTLY. NOW THE COLD WATER COMES OUT FINE BUT WHEN TURNED TO WARM OR HOT WATER TRICKLES OUT

SOURCE: Grohe shower assembly leaking

hiit sounds as though the diverter valve is sticking in the mid position although you have turned it to the floor spout as you call it!!
Also it sounds as though the seals are possibly leaking causing the plasterboard (drywall) to get we, or possibly a joint may be leaking. Advice access the pip-work valve etc run shower & check with torch (flashlight) to see where its coming from?
Rectification work replace seals/repair leak...replace diverter valve assembly.

Kindly

This is a simple fix. The tools you need are: cresent wrench. You want to remove the shower hear off of the pipe coming from the wall. On the inside of the end off the shower head there should be a small plastic disk remove it. It will have a series of holes this is called a water saver. The holes get stopped up with minreals take a tooth pick and clean them out. I see this all the time. If that does not work it will be in the valve

using a pair of vice grips wrapped in a soft towel( to prevent scractching) turn the shower head in a counter clockwise direction to remove it then apply liquid teflon (real-tuf) to the threads on the shower arm and tighten the shower head but dont over tighten it liquid teflon is more effective at sealing leaks than teflon tape and it can be wiped clean

1 Check if the holes in the hand held shower are not clogged with scum which generally happens over prolonged use. Clean them with a pin. 2 If this does not help, then check the the pipe connecting the shower to the water outlet. It should be clean and not clogged with foreign material which restricts the flow of water. 3 It still it does not help then you may have to fix a booster pump or raise the level of the water reservoir.

Sounds like the anti-scald pressure balancing piece is stuck. This happens if the shower isn't used regularly. A varnish from minerals in the water causes it to stick. You can replace the cartridge or try cleaning this one by soaking it in white vinegar. When the cartridge is clean you should hear it rattle when you shake it. To prevent it from happening again be sure to run the hot and cold water at least once a week. BTW, if you are the original owner of the faucet Moen will send you a new cartridge free.
