Better standpipe for overflow box?

[NoLimit]

Hi all! I've been waiting to have a good question for my first post, but this lame one will have to suffice...

I'm trying to find a way to silence my overflow (gurgling, "sucking", etc.)
I've looked at the site for the Durso standpipes, but his don't seem like they're geared toward being used in hang-on overflows -- can they be? If not, has anyone found a good solution? My LFS gave me the idea of using a bioball in the top of the existing standpipe, which kinda works, but doesn't get rid of the gurgling noise.

One more idea: If I could get the water level just about 1/2" above the standpipe, it would be entirely silent -- any good way to add backpressure in a reliable manner (I don't want to have my overflow overflow :lol:

You want the Stockman modification!

Not a lame question at all!

The mod works well for an overflow. That's what I have in my overflow and its nearly silent. To your second question though, you don't want the water to go over the top of the intake. If it does, the small airhole drilled in the top will make a little whirlpool and suck air in. This will restart the noise that the durso just got rid of.

I was able to put a 1 & 1/4" Durso in my overflow box with out too much trouble . . .

Thanks for pointing me in the right direction! Built a Stockman standpipe, and it rocks!

Thanks for the help!
