||Make sure that the technician has a clear path to the water heater.
If the unit is placed in the bathroom, make sure that lights work and that your belongings are clear of the floor in the immediate area of the water heater.
There will be small amounts of water that will be on the floor temporarily as the result of the water heater change.
Your water may be turned off for up to two hours during the change over process. Please prepare by storing any water needed for that time period and delaying projects such as washing until after your installation.
