Plumbing questions
How do I find a hidden water leak?
Turn off every tap and water-using appliance, then watch the water meter. If it still moves, water is escaping somewhere. Closing the main valve and the water heater's cold supply one at a time helps narrow down where.
Why are all my drains slow at once?
When several drains slow down together, the problem is usually in the shared main drain or sewer line rather than any single fixture. Stop using water and have the main line cleared and inspected.
When is a plumbing problem an emergency?
A burst pipe, water spraying, a leaking water heater tank or sewage backing up into the house need immediate action: shut off the water and call a plumber. A dripping faucet or slow single drain can wait.
