I noticed since the winter has started, my hot water for the shower/sink has been totally weird. I have had maybe 3 hot showers (around 11 am each day) for the past 3 weeks or so. I know I could tell my landlord about this, but can it really be fixed or does it just mean so many other people have used all the hot water before I can even get to it? The apartments are broken up into sections, each building must have their own water heater I assume.
