Tips to replace a water heater safely include measuring the height of the previous water heater for comparison and turning off the water heater at least two hours in advance to allow remaining water to cool. Soldering copper fittings prior to screwing them to the tank is also helpful.
When replacing a water heater, it is important to have the assistance of a helper or a dolly to avoid injury. A water heater can weigh up to 150 pounds, so a helper or dolly is essential for removing the old heater and positioning the new one safely.
Another tip to replace a water heater safely involves setting the temperature. This helps avoid burns and injury as a result of scalding or leaking water. The new water heater temperature should not exceed 120 degrees Fahrenheit. When replacing the heater, if a leak occurs, place a pan under the leak. A metal pan is required for gas water heaters.
To prevent injury and accidents, it is best to use a garden hose to drain water remaining in the old water heater. The drain valve on older water heaters can clog, but a garden hose allows the water to drain slowly. The draining water is scalding hot, and as a result, it is best to remain patient.
