How to Replace a Leaky Electric Water Heater Tank

Once your electric water heater starts leaking, it needs to be replaced as soon as possible to prevent a flood or you having no hot water. New electric water heaters are more efficient than the older models and can be installed over a weekend day.

Tools and Materials
  • Electrical tester
  • Pipe wrenches
  • Channel lock pliers
  • Screwdrivers
  • Tubing cutter
Power Disconnect

Turn off the power to the water heater at the breaker box. Open up the electrical cover and use a tester to make sure the unit is off. Remove the wires from the electrical box. Check with an electrician to see if the new unit will require a wire or breaker upgrade. Some old water heaters have undersized wiring.

Water Removal

Turn off the water supply valve, located on the top of the water heater. Hook up a garden hose to the drain valve, located at the bottom front of the water heater and drain the tank outside, in a floor drain, or in a sink.

Piping Disconnect

Remove the water supply lines, using the pipe wrench or channel lock pliers. If you have soldered, hard connections, then you will need to cut out the pipes and re-solder when you install the new water heater.

Earthquake Strap Removal

Remove the earthquake strap with a screwdriver. Now, remove the water tank with a helper.

Installation of New Tank

Install the tank in the reverse order you removed it. Make sure you fill the tank first, then turn the power back on. This prevents the elements from burning out.

How to Replace a Baseboard Heater Thermostat

An efficient baseboard heater thermostat is crucial for your heater's functionality. The best way to ensure that you install the new thermostat correctly is to have manuals on hand for both the thermostat and the heater.

First Steps

When you are shopping for a new thermostat, know that any thermostat you buy should have the same voltage as the heater. Before you begin, make sure all of the power to the heater is turned off. The best way to ensure this is to turn it off at the breaker. Next, remove your old thermostat and mark each wire.


Now that you are ready to begin installation, look at the manual accompanying the new thermostat. It should have a wiring guide in its instructions. This guide will help you correctly wire the appliance. You may need to strip some insulation from the feeder wires in order to properly connect them.


Once you have connected all the wires double check to be sure they are tight and screw the thermostat into place. You should use the mounting screws that came with the thermostat. Turn the power on and check to be sure the unit is working properly.
