Hey guys,
I need help.
Currently, the water flowing through the teeth of the overflow box into the overflow box is very noisy.
Install duoso pipes, but still no use. I guess, duoso pipes are meant for reducing the noise when water is being drained/sucked into the sump.
The noise i am currently facing, is the noise when the water hits the waterlevel of the overflow box.
How can i solve it?
By the way, for the duoso pipes, what does the little hole on top side of the pipe do? Do i close it, or open it?
Thanks!
