On some pumps we can infer that the pump is under abnormal load (too low - no water, too high, seizing bearing) by noting the current draw at the motor. Is there a product we can install to monitor the pressure and kill power to the well if the pressure exceeds the cut-off pressure of the pressure switch? 0000021296 00000 n

Manufacturer: SymCom Model: 233 P Product Information: MichaelYou raise an interesting and useful question: is there a backup pressure limit control suitable for well water pump and tank systems.In fact the pressure control switch itself is supposed to be doing that job.Worse, I fear that when the pressure switch does NOT do the proper job of cutting off the pump (or turning it on when it should) it's usually because the pressure sensing port on the control bottom is debris clogged.So I worry that adding more controls that work the same way will suffer the same clogging - we may be adding complexity without improving the system's safety.We discuss this problem further at WATER PUMP WONT STOP RUNNING https://inspectapedia.com/plumbing/Pump_Runs_On.phpSorry but I don't know an inexpensive duplicate pressure safety switch that uses some different technology to add another control. 0000041864 00000 n
