The purpose of having a low level supply tank alarm is to let the clinical staff know that they are running out of water BEFORE the supply tank empties. If you think that running your $1500 supply pumps dry and have all the dialysis machines in a no water alarm,along with the clinical staff and patients getting upset is just as good, you have alot to learn.

Most PCTs and nurses just mute or ignore the alarm, and continue run the treatments until no water at all. Then, they panic.
Well, I know that times have changed and so are the things we have used, but I still know of approximately 5 clinics that are still using this type of switch, and they have never lost a recirc pump to low water...
Our 250gl storage tank is equiped 4 sensors, at 250gl shuts off the RO, Drops to 100gls then turns on the RO for refill, 1 or 2" below the 100gl is another sensor, this sensor will cut off our distrbution or recirc. pumps if water level drops below 100gl mark if the RO does not come on causing Dialysis machines to generate the "NO WATER" alarm and make our Nurses and Techs scramble and call for help, even though we were all trained on the RO system, and @ 30gl mark it will also shut off our ricirc pumps completely. With our City Water pressure sometimes drops to 5psi and not more than 10 will completely shut down our RO unit,

Hey F-Tech, what brand is your RO. Sounds like the way to go. I'm with you Tommy, it is easier to turn off the alarm than it is to go check on it.

Why do you think the alarm is there? You must have your RO on during normal operation to alert you of high/low level water in the holding tank. If your tank is low (low float) it refills it and no worries. Turn the RO off when your clinic is done for the day or put it in flush. Besides, keeping it on will prevent your cultures and endotoxins from coming back possitive over the action level. From what it seems you need a new RO or a new Tech.
