Water Leaks and Low Water Pressure: What's Causing It

Low water pressure is usually caused by one of a few things: a partially closed shut-off valve, mineral buildup or corrosion inside older pipes, a hidden leak, or an issue with the municipal supply itself.

Hidden leaks are often more expensive to ignore than to fix. A slow leak behind a wall or under a slab can run for months before it's noticed, quietly causing water damage and mold growth the whole time.

Common warning signs of a hidden leak include an unexplained increase in your water bill, damp or discolored spots on walls, ceilings, or flooring, a musty smell in one area of the home, and the sound of running water when nothing is turned on.

Some leaks are easy to spot — a puddle under a sink is obvious. Slab leaks and leaks inside walls typically require professional leak-detection equipment to locate accurately without unnecessary demolition.

If you suspect a leak, don't wait. Water damage compounds quickly, and what starts as a simple repair can become a much larger, more expensive job the longer it goes unaddressed.
