Anyone using a DIY pipe overflow?

That elbow at the end with the open end up (not shown in my pic) will kick in if the overflow slots get plugged. And yes, with a power outage it can only drain down to the level of your lowest slots. And it can't drain below that T at the back either.

Like I said, I tested it extensively, and could not think of a scenario where it could fail. Just make sure everything outside of the water is properly glued and airtight.

Of course the absolute best is a drilled tank, but if for some reason you can't drill it, or don't want to, this definitely works.

I don't understand this design. Do you have an exemple in pics?

So I guess the only disaster scenario is if air gets inside and it lose syphon? then it wont work and the water coming from the sump is going to overflow the tank. I guess putting the pump high enough so not as much water can be sucked if it overflow is a good practice

Looks great anyway. on a 15 gallons nano I don't want to drill or put anything in the tank beside the pump and that overflow pipe. It really look good with only these.

[quote=daniella3d;668817]What I like about those pipe overflow is that they take very little space and are not so ugly as the boxed ones that are sold. I have a black tunzee one that I don't even use as I find it too ugly and if you want the water level to be high in the tank this thing need to be so high that it is really ugly. The pipe overflow is very nice and can be hidden in a beautiful home made box and the water level adjusted very presicely.

Have you looked at notching the top of the glass and adding an external overflow to your tank? No ugly boxes or pipe in the tank what so ever and no space used up in the tank. I don't know if the tank is empty or not so this may or may not be an option for you.
