Where is the pressure drop in a hot water recirculation system?
The exception will be when there are pressure reducing valves, but that will be covered in a later article. The pressure drop will be in the return piping. Determine the pressure drop of the longest run or worst case of pipe and add any equipment pressure drops at the recirculation flow rate.
Why does my hot water heater have low pressure?
Another common cause of low hot water pressure is buildup of minerals, rust or other sediments that can collect in the tank, outlets, and pipes connected to your water heater.
