  • Valve for reducing pressure. The proper setting in a valve for reducing stress ranges from 50 to 60 psi. The higher psi can damage the dishwasher, water heater, toilet valve, washing machine, and refrigerator ice maker. It indicates that if water drips from the valve, the water pressure is relatively high.
  • Water pressure. The water heater has a pressure gauge in the drain valve or a hose bib. Set the device at or under 60-psi. During the night, set it at or under 80-psi. One that goes above the values requires installing a PRV that avoids safety hazards.
  • Expansion tank. This tank accompanies a hot water tank on a closed plumbing system to control thermal expansion. The air pressure in the tank matches the pressure of the water.
  • Valve for pressure relief and temperature. This part is in the top of a water heater tank; it does open a tank after it goes through an over-pressurization. It releases the air after it opens. The tank can explore and pressurize more if it does not work correctly. Water that drips from the valve indicates a higher water pressure. High pressure and a water tank with no expansion tank suggest installing one.
  • Anode rod. The anode rod helps prevent and reduce corrosion. It also extends the life of a water heater. Turn off the supply for cold water after you turn off the power or gas. Bring relief in the tank’s pressure as you open a hot water tap nearby. Utilize a socket, including an impact wrench that eliminates an anode rod. The rod moves toward the tank and its topmost part next to the cold-water inlet. 

The cap is there over the rod. It is proper if there is some corrosion or pitting in the metal rod. Replace it as possible. But when it is missing, the result is a lost or no smooth surface. One more indication that anode rod replacement is essential if milky water is thereupon flushing the tank. Turn on the supply of cold water after you replace the tank rod. Water will fill the inside tank before turning the power back on the water heater. I guess it’s helpful to read about replacing the water heater before it fails.
