Why do water heaters have a check valve?
Many water heaters have heat traps or check valves in pipes at the top of the heater to reduce wasted heat. These special-shaped valves trap hot water and encourage only cool water to flow back into the heater. This helps with water heater efficiency and ensures that water flows in the right direction. But as water moves through the valves, changes in pressure from different water temperatures create ticking sounds.
Why does my water tank make a popping sound?
