Replacing a 20-Year Old Water Heater

Recently, we had the opportunity to replace a water heater that had been working overtime for 20 years. This project was a great reminder of how important it is to upgrade aging appliances before they cause significant issues.


Here’s a look at how we took this water heater replacement from a problem to a perfectly finished project.


The Challenge: A Leaking and Rusty Water Heater

The original water heater had seen better days. After decades of use, it had developed rust, which posed a contamination risk, and it had begun leaking, threatening the surrounding area with water damage. At this point, it was clear the unit had reached the end of its useful life.


When we arrived, we saw the full extent of the situation and got to work immediately, ensuring we addressed not just the old water heater but also prepared the space for a clean, efficient installation of the new unit.


Our Solution: Installing a Modern Water Heater

For this project, we selected a high-quality Rheem water heater, known for its energy efficiency and durability. This unit was an excellent choice for the homeowner, offering modern technology to meet their hot water needs while also saving energy.

The One A+ Plumber Installation Process

Here’s how we made it happen:

  1. Assessment and Removal

    • We started by turning off the water and power to the old water heater to ensure a safe working environment.

    • After draining the tank, we carefully disconnected the unit and removed it from the property. This step also allowed us to inspect the area for any damage caused by the leaking.

  2. Preparing the Space

    • We cleaned the installation area thoroughly and added a new drain pan for extra protection in case of future leaks.

    • With the space ready, we positioned the new Rheem water heater to ensure it was secure and level.

  3. Plumbing Connections and Safety Features

    • Our team expertly connected the new unit to the existing plumbing system, ensuring all connections were tight and leak-free.

    • We installed a pressure relief valve and an expansion tank to enhance the system’s safety and efficiency.

  4. Testing and Final Adjustments

    • Once everything was connected, we turned the water and power back on, checking for any leaks and testing the system to confirm it was functioning perfectly.

    • The final touches included securing pipes, labeling valves, and ensuring the homeowner understood the features of their new water heater.
