We recently purchased the above 40 gallon water heater. We were charged $800. I did not see it until after installation. It sits so low to the ground (much lower than its predesessor) that I am concerned if we get water in the basement, it would not take much for the water to get inside the unit. I think it would take a minuscule amount of water to wreck the water heater. Is this correct? The installer wants to charge $200 to place bricks under the newly installed water heater to raise it up some and reconnect it. I wish the installer would have asked us before installation about the wisdom of raising it. Although we rarely get water in the basement, it is a worry. Should we pay more to lift the water heater?
