I've suddenly lost pressure only in 1 of 2 upstairs bathrooms.
Both hot and cold are completely off.
Both the sink and shower are affected. A second upstairs bathroom and the downstairs kitchen are fine. I removed the aerator on the sink and I removed the shower head- no help.
It is freezing outside, but I don't see how both pipes only to one room would freeze. No signs of leaking (yet). I cannot see where the pipes from the shower and sink diverge- beneath floor or in wall between the floors.
