DO NOT BUY WHIRLPOOL HOT WATER HEATERS! THEY ARE JUNK AND WHIRLPOOL DOES NOT HONOR WARRANTY! CUSTOMER SERVICE IS HORRIBLE AND I WAS MADE OUT TO BE A LIAR AND HUNG UP ON. I WAS TOLD THAT I NEED TO SPEND MORE MONEY TO HAVE AN EXPANSION TANK INSTALLED! DON'T KNOW ANYONE IN MY FAMILY OR NEIGHBORHOOD WITH A LEAKY HOT WATER HEATER THAT IS LESS THAN 5 YRS OLD AND HAS LEAKED SINCE DAY ONE.
