So I’ve finished my plumbing and have been playing around with the flow. I’ve gone with a herbie- 2 overflows each one has a siphon drain with gate valve at sump side, an emergency standpipe and a return. The issue I’m coming across is that in order for the overflows to run silent, I have to have much more than a trickle down the emergency drains. Otherwise, with a trickle it’s very gurgly and loud. Is there any issue doing this other than the water going down the emergency is bypassing my filter socks? Are there any tricks other than using the emergency in this manner to having it be silent? Thanks.
