My upstairs bathtub/shower has no water pressure.
I changed the water cartridge and it worked fine for 2 days. Now, I have no water what so ever. I even had the water on and removed the cartridge expecting water to spray out, not a drop. The weather is abnormally cold here, around 2 degrees not counting wind chill, but every other faucet in the house works, including the sink in the upstairs bathroom. Could I have a frozen water line just going to the bathtub? I'm not sure how the lines are run through the house.
