4. Damaged Walls, Ceilings or Floors
Water stains, soft surfaces and sagging are signs of a leaky pipe. While these issues can occur in rooms with poor ventilation and high humidity, they’re especially problematic if you’re having other signs of a leaky pipe.
5. Knocking Pipes
Hearing a knocking noise in your plumbing system while running water isn’t normal. The noise may indicate your pipes are loose or close to springing a leak.
6. Low Water Pressure
Insufficient water pressure can be caused by a clog, burst pipe or damaged water heater.
7. Not Enough Hot Water
Your water heater has a limited capacity, but getting cold water when you haven’t used a lot of hot water is a sign something is wrong. Your water heater might be leaking or malfunctioning.
8. Discolored Water
Water that’s a strange color could be hazardous to your health.
Brown, red or yellow water means you may have rust in your pipes, a water main break in your area or old pipes. Green and blue water is especially serious, since it means your pipes could be corroded.
