My overflow failed today :(

It might be easier to use a float switch to shutoff the pump in the event of a low water event in the sump. You could use an ATO system for this purpose. Most ATOs can be configured with a sensor in the reservoir to detect a low water condition and shut off the top off pump. Theres no reason why this wouldn't work with your sump and return pump.

Anyway, I'm sorry about your misfortune although I'm glad you didn't lose the tank.

sorry to here, but glad to hear that it wasn't a complete catastrophe. Still, not something any of us want to come home to.. I'm curious as to what type of external overflow you are using that failed? Durso, Herbie, single stand pipe, siphon?

This is a great idea if you don't have a big ATO reservoir connecting to the system directly. Else your low switch wont activate uitl the ATO reservoir is out of water.

What i do on my is that put a high float switches on both my sum and my display tank , if the water reach these levels, my pump shut off. Also have the water floor detection as well to shut off everything. Cant afford any water on my carpet or my wife will kill me


Also, about why you are getting overflow, i found that sometime if your overflow water has to travel horizontal to get to your sump, the air get into there and build it the back pressure which cause water could not drain fast enough

HOB overflow = russian rulette.

by external do you mean you have a HOB overflow? If so then its an accident waiting to happen.

I agree if it depends on a pump like an aqualifter to restart siphon.
I its a utube overflow, you should not have failure for any reason.

Going on 4 years with my current DIY overflow never, ever failing.

People who say it's an accident waiting to happen are just ignorant on this subject...likely from lack of experience.

What kind of external overflow did you use?
If it happened once, it will happen again if you dont figure out why and how.

Thanks for the responses guys. It's a Lifereef utube overflow and has worked flawlessly for 2 years. I think something plugged the utube for awhile and then moved on, although I don't have any evidence. I have one hermit which is big enough to plug it and it can climb the glass. I do have an ato and it did activate but luckily it shuts down automatically after about 10min so some damage was contained there. A high water float switch in my display may work but it may be an eyesore IMO if I can't hide it. Can a controller like an apex or something control a floor water sensor to cut off my return instead of just sending an audible alarm? Is there a cheaper or easier way?

an apex + io break out box + http://www.amazon.com/gp/product/B000BKQ75G will cut off your return pump

LOL...
That's the cadillac of external overflows...
I would bet money it was an animal that clogged your utube...
Thats why I run dual tubes...lol.

This same type ofmalfunction could occur in any overflow, external or otherwise without the proper failsafes.
