Jus got a durso pipe installed because of the air sucking in my overflow and the noise was driving me crazy.
But after getting it done, the water splashing into the sump, the over going into the overflow and the durso pipe are making more noise.
I reduced the flow for my return pump and the sound is lesser. But i get some kinda whistling sound coming from the top hole of the durso..
I need help.. its driving me crazy.
