Drains-bubbles and noise

[DonW]

I attatched a quick sketch of my drain plumbing all 1 1/2. Can anyone see a reason for tons of bubbles and noise.

Thanks
Don

I Figured It Was Normal Mine Does The Same Thing . If Not Than What Are We Doing Wrong.

Hey Don,
Noise from water hitting the sump or from the overflow? Bubbles will always happen because you mix the water with air to take it to the sump. So do you have a problem with bubbles going into the sump or back into the tank?

I was getting a lot of slurping noises from my overflow. I ended up throttling back the ball valve between the overflow and the sump and the noise and bubbles went away. Hope that helps some.
