Got lucky tonight..

Sooo I usually check my sump once a day(water lever etc..)..well ive been busy the past two days,and tonight when I came home I looked under the tank and saw may ATO switch off to the side and my sump level in the danger zone.....so for the next few hours I will be adding RO/DI to slowly bring back my spgr...close call a few more hours and I would had a burnt out pump or worse...going to order a better float switch holder(the one I was using had suction cupsnever been a prob over the past 4 yrs).going to order the DA double float holder...live and learn my friends..always something when you least expect it..::::

 

Wow. Good catch.
I've never used them, but if you want for piece of mind and some added safety, they do make run-low switches to turn your pump off in these cases. FWIW

 

You know Matt you make a good point.Thanks..I have been meaning to get an extra plug to run one with my RKL(only using one switch port)....now will be a good time to do so..

 

Its funny how you can buy the best productX money can buy and it still all comes down to a little suction cup!! You could also try putting putting a timer on your ATO for a redundant safety measure. Mine is set to come on 4 times a day at 1 minute each. If the tank does not need a toping off at one of the selected times the ATO simply does not activate.

 

I hear ya on that...I've tried to get the timer work with my float switches on the rkl,but can't for the life of me get it to work smoothly..what you described would be what I was trying to do originaly....what setup are you using?.......thanks..

 

thats rad dude! props

 

glad you caught it before it was a problem. Get a Tunze 3155 the magnet holders for the sensors are super strong, you will never have an issue with them falling off. It's a higher priced ATO but $180 vs piece of mind is $ well spent IMO. It's my first ATO and I absolutely love it.

 

The biggest issues with low water in the sump are the salinity change and in-sump protein skimmer efficiency, not the risk of a pump burning out. You would see bubbles getting sucked into the display tank as the clue that something is wrong in the sump well before a pump is in any danger.

It takes a lot to burn out a good pump. I've had a pool pump literally running almost dry for more than 24 hours when we were out of town and had an issue with a leak. As long as there is some water going through the pump to keep it moderately cool, a decent pump won't burn out.

 

your def right,thats why when I replaced with RO/Di I did it over the coarse of the night..as not to swing the spgr to much..

 

Thanks,but im either going to try and place a magnet onto my holder or go with the DA one that hangs over the side and can hold two floats..
