What Causes Sudden Leaks and Backups
A sudden leak usually comes from a failed joint, a worn supply line, or a fixture seal that has given way. A backup usually means a blockage in the drain or sewer line, or a full septic tank. Water pressure changes and cold snaps make both more likely.
If water is running and you cannot stop it at the fixture, shut off the main supply valve and call (770) 764-0768. For a gas smell, leave the building and call from outside.
Warning Signs You Should Not Ignore
Water stains on ceilings or floors, a meter that keeps turning with everything off, slow drains in more than one fixture, and a water heater that will not heat are all signs a system needs attention. A sewer smell indoors often points to a dry trap or a vent problem.
Acting on these early usually means a repair rather than a replacement. Waiting often means water damage or a larger bill.
What You Can Safely Check Yourself
You can locate your main shutoff valve, check the water meter for movement, and look under sinks for damp joints. You can also test a water heater's temperature and reset button if the manufacturer's instructions allow it.
Do not open gas lines, cut into walls, or work on sewer lines yourself. Those jobs need a licensed master plumber and, for gas, a licensed professional.
