Professional diagnosis and replacement of expansion tanks and TPR valves. Prevent leaks, banging, and costly damage.
The expansion tank on a water heater is one of the smallest components in a residential plumbing system, and one of the most commonly ignored. When it fails, the consequences range from minor leaks to ruptured tanks and full-room flooding.
Koda Plumbing Service Co treats expansion tank and pressure relief valve work as scheduled maintenance. A planned replacement is a one-hour appointment. An unplanned failure is often an expensive emergency.
Every service in Brickerville follows the same proven process.
