As you can kind of see, the emergency is tee'd into the main drain line. I wish this would have been on its own drain line because tuning this herbie in for silence is very difficult when the sump is in the basement. Sometimes gravity pulls air through the emergency line when draining through the normal drain line, creating a loud air suction noise. It was very finicky to tune and as soon as the sump level changes by mere millimeters it starts all over again (thanks for ATO I don't normally have to mess with it)

Please note that there are ABS fittings on the drain line. It's not ideal. You want to choose either PVC or ABs and not interchange them but because this is only a drain line it's not that big of a deal (it's not under pressure).

Here's the sump before we fired everything up:

Since this pic we've added a check valve on the return line. This prevents water from back syphoning through the return lines in the main display in case of power loss.


Here's how we covered up the drain lines:

thank you!
 

Ok thanks everyone. I really appreciate it.

Tank is being delivered tomorrow (supposedly). So a friend is coming over tomorrow evening and we're going to try our hand at plumbing it. No previous experience (with either plumbing or keeping a reef tank!).

If anyone can point to a good start to finish herbie tutorial, I would appreciate it. Something like the BRS video but with a bit more detail.

I'm also a little lost of how to plumb into the sump. And as my question that started this thread proved, also a little lost on the return line plumbing!

Thanks guys!
