This morning hot and cold water stopped running in about half of the faucets and toilet tanks in my house. If it would happened to either hot or cold water I would think the line is blocked, but both hot and cold stopped at the same time and only some lines affected, the half lines are fine and I have one water heater. Can anyone guess what can be wrong?
If flow stops in both hot/cold, the stoppage has to be before the branch to the water heater. Not knowing how your house is plumbed, it is difficult to speculate much further. Could be a filter, water conditioner, etc.
