Does bulkhead size matter?

[tHeHEYzeus]

Yah that makes a lot of sense thank you, what is the deal with the noise? Do smaller pipes make more noise?

[Bloodasp]

not really. kind of similar to your sink, bathtub or toilet, when water drains you sometimes hear a gurgling noise, which is sometimes pretty loud. same thing happens when water drains from your main tank to your sump.

large bulkhead for you drain since just gravity whereas the return is under pressure so can use the smaller.

A open drain will cause noise. Since you only have the single drain, look into the Durso, Stockman or Hofer to help quiet.
