JBJ ATO overflowed my tank
I got home yesterday to about 3 gallons of sw on my hardwood floors and my salinity down to 1.20
I checked the float sensor and it looked fine floating high and in the same position it always is. Any ideas why it would pump 3 gallons too much water into my tank. I don't see how anything got up to it, but you never know. Thanks Dave |

Thats interesting...
I have that same device and I had to take it apart to update it to work longer. My problem was that it would turn off too quick and then stay OFF. So I found a site that had an update that you can perform with a screwdriver to change the pump turn off time to 14 min.. This is the MAXIMUM setting. What size pump are you using to top off the tank? I use and aqua lifter. I can't imagine an aqualifter pumping 3 gallons in 14 mins. By default the unit should be set to turn off in 3mins. Are you using 1 float or 2? I only use one float switch but two is safer and I would recomend you look at that senario. Thats way if the second float is tripped it will shut off the ATO.

I have the same unit.
When I set mine up I set it up so the 2nd float switch will shut the system off if the 1st float switch gets stuck. Here's how I did it. Unit set to Mode A. Place 1st float switch where you want your level to be. Place your 2nd float switch about 1" above your 1st float switch Then last invert your 2nd float switch, (turn it up-side down) this way if your 1st sticks the 2nd will shut the unit off. Keep in mind however doing it this way takes away your ability to place the 2nd float switch in your reservoir to keep from running your pump dry. Anyway. it works for me. |

yeah, I want to do it with two. but my problem is I am running this in a small tank with no sump. I keep my tank filled to the top, there is no way to add the second switch to the display and get it to be at a safe level to stop the pump unless its sticking out of the tank, at that point it would be already overflowing.
Im using a rio 600 pump since I have to lift the water about 5 ft up. |

Put the controller right underneath the part of the tank that will overflow first, and hope the thing will just burn out next time...

ATO FAQ These are not the best solutions but they may prevent another flood of salt water. I would try to aim for 1 min longer than it takes the pump to top off. This way if it does fail it will shut off no matter what the state the float switch is in.

Im going to start leaving less water in the bucket and and checking the level more often so if it sticks again it runs out of water or the 2nd float shuts it off. It pumped a ton in, but not enough to get to the float in th e bucket. Its wierd because when I got home, everything was opporating perfectly.

You can run two float switches in series so that both of them have to trip in order for the pump to kick on. And, as soon as one hits the level, there is half the chance that it will overflow. And this will allow you to keep the one in your freshwater bucket.

Most float switches aren't meant to be submerged, and ones that are most of them leak. So after they go under they should be replaced. |
