I have recently moved into a flat. At first the shower was luke warm, so I tried to turn the value to make it hotter, but it didn't seem to make a difference even though the pipe was very hot, now the pipe is very cold and there is no hot waer atall in the shower but there is in the sink in the same room. I took off the shower pipe and it runs out fine, the pressure is there just not the heat. Any help would be much appeciated!

What brand of faucet is it? You may be able to adjust the scald limiting device locatd under the handle or you may just need a complete new cartridge(not all that uncommon)

Hi thanks for the reply, There is no brand name on any of the faucets which doesn't help much, It is a thermostatic one though if that's any help? I will try the scald limiting device

Micha, you said flat, so you are renting, right? Do not try repairs if you are renting. Your will be held res[ponsible for any damages and the owner should do the repairs for you
