How to Double the Life of My Water Heater
Sep 22, 2021
Local and state governments create laws, rules, and codes to regulate the materials, design, and installation of many things including the water heater. The Georgia State Minimum Standard Plumbing Code has some rules concerning the water heater installation and Just Water Heaters is here to break down some of these codes. If you have any specific questions or concerns, or if you would like to hire a specialist for a water heater installation, replacement, repair, or maintenance, then call Just Water Heaters. We are always happy to help and even arrange an emergency dispatch.
If you are using a space heating system that requires water for heating at temperatures higher than 140 degrees Fahrenheit, then you must have a master thermostatic mixing valve that complies with ASSE (American Society of Sanitary Engineering) 1017. This mixing valve should limit the water in the water heater to a temperature of 140 degrees Fahrenheit or less.
There should be drain valves installed at the bottom for emptying the tank. Drain valves should conform to ASSE 1005.
Water heaters should be third-party certified and located in an area that allows access for observation, maintenance, repairs, and replacement.
Storage tanks and water heaters in domestic properties should have the allowable working pressure clearly stamped in an accessible position outside of the tank to make inspection readily possible.
The water heater must have automatic temperature controls capable of adjusting the temperature settings in the operating range.
The water branch line from the main water supply line to each water heater should have a valve located near the unit and serve only that specific water heater. The valve should not interfere with the cold-water supply to the remainder of the cold-water system.
Further, there should be connections to provide proper circulation of water through the water heater.
There should be an antisiphon device, such as a cold-water dip tube or vacuum relief valve, installed to prevent siphoning of any storage water heater. The vacuum relief valve shall comply with ANSI Z21.22.
There should be a means to shutoff the electric hot water supply from its energy source in accordance with NFPA 70. There should be a separate valve to shut off energy supply to all other types of hot water supply systems.
Storage water heaters operating above atmospheric pressure shall have a self-closing pressure relief valve and temperature relief valve. These should conform to ANSI Z21.22 and should not be used as a means of controlling thermal expansion.
The relief valve shall discharge to a safe place of disposal outside of the building. The discharge shall operate in a way that does not cause injury to peoples in the immediate area or structural damage to the building.
A pan made of galvanized steel having a minimum thickness of 24 gauge shall be installed under tank-style water heaters.
