Hot Water System Leaks
Understanding Hot Water System Leaks
Water appearing from a hot water system where it hasn’t before can be a sign that requires attention, though not always immediate panic. The temperature and pressure release (TPR) valve on storage hot water systems is designed for occasional water release to manage internal pressure, so a minor drip from this point is not unusual. However, a continuous stream from the TPR valve suggests it may be faulty or obstructed by sediment, indicating a need for professional assessment. Any other water flow or drip from the hot water system beyond the TPR valve is generally a concern and warrants further investigation.
Addressing Leaks and Potential Causes
If water is gushing from your hot water system, it is crucial to take immediate action by turning off the water inlet valve or mains water supply, and then promptly disconnecting the power to the unit for safety. Even a slow leak warrants a plumber’s review, as it can signal more significant underlying issues that could worsen over time. Possible causes of leaks include a corroded storage tank, often due to sediment buildup and a neglected sacrificial anode, or damage to pipes and fittings from corrosion or exposure. While leaks from pipes or fittings are often repairable, a cracked or severely corroded storage tank typically makes replacement with a new, potentially more energy-efficient system a more cost-effective solution than attempting repairs.
