The Durso Style drain reduces that noise level considerably when tuned correctly. The faster that water is moving, the louder it would get. In days past, noisy drains were problematic because the water would splash and gurgle as it passed through the pipes and down into the sump. The Durso Standpipe was created by a hobbyist, Richard Durso, and was born out of the desire to quietly and efficiently drain water from the display aquarium down into the sump. This is the most basic of the drains styles that only requires a single hole to be drilled into the tank. All of them can be used with either an internal or external overflow box. These are the three most common water drain technologies you will see used on an aquarium.
Durso, Herbie, and BeanAnimal refer to the drain plumbing itself inside the overflow box. While there are several different types of overflows using a variety of different drain styles, they all accomplish the same thing - drain water from your display down into your sump or filter.Īn overflow box can be internal or external meaning the box is either inside the aquarium or outside the aquarium. The overflow box itself consists of a weir and drainpipes to get water out of your tank and down into your sump. An overflow box is used to drain water from your display aquarium down into your sump or filtration system.
