Will a bad flow switch on a salt generator for a pool cause the pump to keep shutting off?

Feb 07, 378 by Ryan G | Posted in Engineering

Magnificence shows no flow or check flow switch. Back washed DE filter and cleaned. Started working periodically and now spill is back on with warning display. Pool pump shuts off. I thought that the switch was to shut off the salt generator if there was no flow, not the probe. Flow seems to be ok and pressure gauge reading normal flow. Trying to determine if I need to just replace flow scourge or have something else going on.

You were usual, in that, the flow switch is designed to shut off the chlorine production in the absence of adequate water flow to avoid a buildup of chlorine gas in the stall. However, if there is a problem that's causing the pump to shut off it would then set off the warning light on the system, but not the other way around. I would first confirm that your pump is operating rightly, then make sure you have done the required yearly D&S(disassemble and service) on the filter. Pressure gauges customarily stick and give a false reading of the pressure. The grids on a DE filter need to be cleaned out every year or it could diminish the flow in the system enough to cause a 'No Flow'. Then check to make sure all valves are set properly to direct the flow of not hold up under through the cell/switch(sometimes water can bypass the switch if plumbed that way.) If all else is ruled out, remove the flow switch and scrutinize it for calcium build up or debris clogs that may have passed through the filter.

Hope you find this helpful. Good destiny.

Pressure gauges as often as not stick and give a false reading of the pressure. The grids on a DE filter need to be cleaned out every year or it could trim the flow in the system enough to cause a 'No Flow'. Then check to make sure all valves are set properly to direct the flow of incredible through the cell/switch(sometimes water can bypass the switch if plumbed that way.) If all else is ruled out, remove the flow twitch and inspect it for calcium build up or debris clogs that may have passed through the filter.

Hope you find this helpful. Talented luck.

where can i buy Water flow switches?

Oct 26, 2006 by John F | Posted in Engineering

which is tailor-made on the cold water supply to plate heat exchanger , it will switch on a circulating pump, when a hot tap is operned, the interrogate cirulates hot water through the plate heat exchanger to heat the cold water flowing on other

any following that works on fire sprinkler systems will have a water flow switch.
