instead of controlling your drain, control your return[/QUOTE

Yup I have a gate valve on my return as well.
Maybe i'll bring my water level up in my overflow so I have a trickle in my emergency. Just dont trust it as it's overflowed once before and I was assured that the emegency would handle it. The 2 emergency drains are teed in to one that drains in to the tank. I miss my Durso


Thanks for all the suggestions guys

Kien brings up some really good points. My sumps have always been designed in a way that the water height where the overflow enters the sump doesn't fluctuate. I don't use socks either, I use a filter pad. I've always had my overflow under water in the sump.

I do occasionally adjust mine, maybe once every few weeks I have to dial it open a bit because I'm getting too much down the emergency, and it never fails that a few days later the main drain with the gate valve starts sucking air. I'm sure it's just a gob of something sitting on top of the gate valve. I know on my system, the gate valve is barely open at all. It seems like it's turned open a lot just by the number of turns, but when I remove it and look (it has a union above it) it's only open a fraction of the pipe diameter. Maybe that has something to do with it - that's been on a constant on my Herbie-plumbed tanks.

So, to recap, instead of controlling your drain, control your return

Uh Greg, that's not a Herbie then.

Well it took me 4 hours last to get it dialled in to where I like it. And I slept on the couch in fear of a flood. I've got a good silent trickle. So far I haven't had to cut the emergency drains down and if it does come to that I think I'm just gonna cut some notches in the top of them instead. It took just a little under 10 gallons of water to raise up the water in my overflow to reach the emergency drains.
