My overflow failed today :(

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

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

Not sure what size of display tank you have but after adding up all the parts needed, you probably should look at the cost of a new tank with overflow built in. My guess is it wouldnt be much more for a new custom tank... few hundred more?

Thanks. This could be the perfect excuse to buy an apex!

I don't blame the overflow because it did return to full flow on it's own so there was no break in the siphon. Right now I'm blaming my biggest hermit and Im thinking of trading all my big hermits in for little ones.

The tank is 70 gal and it would be nice to get a new drilled tank but it would be a pita to switch over.

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.

Nope, it could Never be the Lifereef's fault!

Here we go again...

LOL indeed.
