De rod can help eliminate the odor problems. Dip Tube The dip tube is a long narrow tube that directs incoming cold liquid to the bottom of the tank, preventing pre-mature mixing of incoming cold liquid with the out going hot liquid at the top of the tank. Without the dip tube, or with a broken dip tube, it may seem as though you run out very quickly, or you just get a luke warm temperature. Thermostat The thermostat senses when the tank drops below a certain pre-set temperature and causes the burner to come on. When the desired temperature is reached, the thermostat shuts off the burner. There is a knob that allows you to set the temperature to warm med or hot. Drain Valve The drain valve allows the tank to be drained for various reasons including periodic removal of sediment or for replacement. In areas with high mineral content, it is recommended to drain at least 5 gallons from the drain valve every six months or so to prevent sediment build up. Avoid cheap plastic drain valves tha
gas water heater Essure Relief) also known as a T&P valve gas water heater, pop-off valve gas water heater, or just relief valve gas water heater, is a safety device on gas water heaters that releases pressure from the tank if the pressure or temperature reach unsafe levels. The TPR valve is usually mounted on the top of the tank gas water heater, but can sometimes be mounted on the side of the tank. A manual release lever located on the relief valve. According to most manufacturers elief valves should be periodically tested by lifting the manual release lever at least once a year. Due to the scalding potential of the discharge from the T&P valve gas water heater, the outlet from the valve should be piped to a safe area. Typically they are piped down gas water heater.
gas water heater to within 6 inches of the floor or even outside of the dwelling at near ground level. Check with your local building department for local building code requirements related to the relief valve discharge plumbing. Anode The sacrificial anode is a metal rod usually magnesium or aluminum which helps prevent corrosion of the metal tank. Electrolysis eats away the metal anode instead of the metal of the tank. Once the anode is gone the tank itself begins to corrode. To prolong the life of the tank gas water heater, make sure your anode rod is still there gas water heater, and replace it when needed. The anode is screwed into the top of the tank and can be replaced. Sometimes the anode is built into a special outlet fitting. Softeners can cause the anode to wear out more quickly. Bacteria can react with magnesium anodes causing hydrogen sulfide which can cause a rotten egg odor. Switching to an aluminum anode rod can help eliminate the odor problems. Dip Tube The dip tube is a long narrow tube that directs incoming cold liquid to the bottom of the tank gas water heater, preventing pre-mature mixing of incoming cold liquid with the out going hot liquid at the top of the tank. Without the dip tube gas water heater, or with a broken dip tube gas water heater, it may seem as though you run out very quickly gas water heater, or you just get a luke warm temperature. Thermostat The thermostat senses when the tank drops belo.

Er possible causes are clogged burners and low gas pressure and are beyond the scope of this guide. Problem: Slow hot water recovery. Sediment buildup in bottom of heater, flushing the water heater may help. Other possible causes may be insufficient combustion air caused by insufficient ventilation, or improper burner operation. Problem: Discharge from TP relief valve. The relief valve will operate if either the water temperature is to high or if the pressure gets too high. If the inlet to the water heater is fed directly from the water main with no pressure relief valves or check valves between them then when the water heater heats the water and it expands, the extra volume of water simply flows back toward the water main. If however there is a blockage such as a check valve or pressure reducing valve with a defective bypass then the increase in water volume has no where to go and the pressure with increase dramatically. Placing an expansion tank in the line at the inlet will give the
