Signs of needing Repair
- Unexplained increase in water bills – A sudden spike often points to a hidden leak in the main water line.
- Low or inconsistent water pressure – Cracked, corroded, or leaking lines can reduce pressure throughout the building.
- Discolored or rusty water – Brown, cloudy, or rusty water may indicate corrosion or deterioration in the water line.
- Wet spots or pooling water – Standing water, soggy soil, or pavement settling near the building can signal an underground leak.
- Sounds of running water – Hearing water flowing when no fixtures are in use often points to a leak in the supply line.
- Foundation cracks or water damage – Leaking water lines can weaken soil and cause structural issues over time.
- Mold or mildew odors – Constant moisture from a leaking line can lead to mold growth inside walls or floors.
If any of these signs are present, it’s important to have a licensed plumber inspect the water line promptly to prevent further damage, water loss, and costly repairs.
