Water heater leak and no hot water issue from a Cary, NC based customer. This installation includes a 50-gallon direct-vent natural gas water heater, which features sealed combustion to improve safety and efficiency. The system draws fresh air from outside your home and vents exhaust gases through the wall, ensuring that indoor air quality is maintained. The water heater’s glass-lined tank provides added protection against corrosion, making it a durable choice for installations that require isolated combustion. We also installed an ST-5 thermal expansion tank, which is designed to absorb pressure increases that occur when water is heated in a closed plumbing system.

Frequently Asked Questions

A direct-vent water heater is a sealed-combustion system that draws fresh intake air directly from outside your home and expels combustion gases back outdoors through an exterior wall. It is ideal for utility rooms, closets, or enclosed areas without adequate surrounding air for combustion, ensuring safe operation and protecting indoor air quality.
Standard gas water heaters draw air from inside the room, which can risk backdrafting exhaust fumes if room ventilation is restricted. Sealed combustion operates on a completely closed loop, preventing dangerous gases like carbon monoxide from entering your living spaces.
Leaks are frequently caused by internal tank corrosion, excessive water pressure, or thermal expansion stress. While leaking fittings or valves can usually be repaired, an actively leaking tank indicates the internal lining has compromised, requiring a full system replacement to prevent structural water damage.
Water expands as it heats up within a closed plumbing system. An ST-5 thermal expansion tank acts as a pressure buffer by absorbing excess water volume during heating cycles, protecting your new water heater, pipes, and fixture seals from strain and premature failure.
A glass-lined tank features a specialized porcelain-ceramic coating bonded to the inner steel wall. This durable barrier shields the metal from continuous contact with water and mineral deposits, dramatically reducing corrosion and extending the total operating lifespan of the system.
Our technicians verify proper gas pressure, inspect exhaust vent line seals, confirm temperature output, and test all safety relief valves before finishing the job. We also conduct a whole-house inspection of your main supply lines and shutoff valves to ensure overall system reliability.
