shutup

[superduperwesman]

I'm not entirely sure what a herbie is??? But I just go with two drains.... on with a gate valve and one as a back up.

I kept the gate valve low, close to the sump, and adjusted it to match the in flow so the pipes are entirely void of air and then I had no water noise. Because the restricted drain is submerged so it is sucking absolutely no air. As the lines get nasty you have to occasionally adjust the gate valve but you'll know when you need to because you'll hear water going down the other drain


*Edit: ok that was a terrible explanation... yeah just go look at his journal^ same deal.... you wont hear anything but the pump
