Aquarium Overflow Silencers
Push-on air baffles that break up falling water and bleed air on a Schedule 40 standpipe.
It works with a Herbie style or BeanAnimal style drain. Small vanes break up the falling water and side slots bleed air, which takes the gulp out of the drain.
Overflow silencer questions, answered straight.
Does the silencer work with my style of drain?
It works with a Herbie style or BeanAnimal style drain, the two most common quiet drain setups.
How does the silencer quiet the drain?
Small vanes break up the falling water inside it, and side slots bleed air. Trapped air is what makes most drains gulp in the first place.
Why do you not list a decibel or noise number?
Results depend on your own plumbing, drain style, and flow.
What pipe standard is the silencer sized for?
It is sized to a Schedule 40 standpipe, the standard most overflow drains use. Our two sizes cover 1 inch and 1-1/4 inch pipe.
Can I use the silencer on any overflow, not just Herbie or BeanAnimal styles?
It is built for Herbie style and BeanAnimal style drains. Those two are what it is designed around.
