Water Heater Check List after Installation
After you have installed the new connections, dry them with a paper towel or toilet paper. About 10 minutes after you have turned on the electricity you should hear a noise in the water heater or feel warmth beginning in the pipes. Now re-check the pipes and see if there are any leaks. Also, check the thermostat to see if they are set at the desired temperature. Some water heaters have an upper and lower thermostat and some only have a lower thermostat. You will need to set both of them, if equipped with two. Setting these thermostat over 140 degrees can cause excessive wear on the heater elements.
