I just moved into a new apartment. I noticed that the pressure in the shower is not optimal, but the hot & cold water work fine. After changing to a higher pressure shower head, the pressure is much better, but now I have no hot water (unless I turn the faucet to the hottest setting, then there's some hot water).
I'm quite sure that it's somehow caused by the new shower head, because when switching back to the original I'm back to where I started. I can easily try a different shower head, but without knowing the root cause, I don't know what to look for.
Is this a common issue? Any suggestions on how to fix it?
Thanks in advance
