How to Do Water Heater Installation Safely
Water heater installation is a major home improvement project that requires the use of tools and experience. Whether you want to install an old tank type water heater or a new tankless unit, it’s important to know how to do the job safely so you can avoid potential issues and costly repairs down the road.
Cost of Water Heater Installation
The cost to install a new hot water heater depends on the size and model you choose. You’ll also need to consider the amount of labor that is involved, which can add anywhere from $45 to $150 per hour to the overall cost. In addition to the price of a water heater, you’ll also need to account for any additional costs related to venting, plumbing or electrical work.
Before you begin, it’s important to check the wiring connections for safety. To do this, turn off the circuit breaker that controls the power supply to the heater. It’s also a good idea to make identifications or photographs of the wires you will need so you can connect them correctly later.
Drain the Tank and Wiring
The water heater’s tank must be drained to prevent damage to the unit and the electrical system that feeds it. A drain valve is located at the bottom of the water heater and can be used to flush out the internal components. You can also open the temperature and pressure relief (T&P) valve to allow air into the tank, which can help drain the water faster.
Afterward, you’ll need to disconnect the water and gas lines that feed the heater and dispose of them properly. You can then attach a hose to the drain valve on the heater and let it flow into a bucket or floor drain.
Remove the old tank and install the new one
The actual water heater installation usually takes about 45 to 60 minutes, but it could take longer depending on the size and brand of the unit you’re installing. The installation process includes removing the old tank, connecting the cold water line and repositioning it into the new tank. Once the new water heater is in place, it’s time to install the electrical wires and a thermostat that regulates the temperature of the hot water.
If you’re unsure of how to do the task, hire a plumber to complete it for you. A professional can ensure that the water heater is installed correctly and safely and that all safety precautions are taken to keep you and your family safe.
Prepare the Water Pipes
If your old water heater uses copper pipes, then it’s a good idea to rub the ends of the pipes with a sandpaper cloth to smooth them out and shine them up. This will help to minimize corrosion and protect the pipes from future leaks.
Measure the water lines before you start to ensure that they fit the new water heater correctly. If the lines are too long, cut them down so they’ll be easier to handle when you connect them.
