herbie drain system

There's two valves I'd like to plumb horizontally. Can I achieve full syphon with a gate valve on a Herbie main drain, if the gate valve is plumbed horizontally? Will a Y-style check valve (pictured) still work properly, if plumbed horizontally? I believe this is also called a Wye Check Valve...

Hi Guys I am setting up a new tank (first in a good few years - 135g dt, 40g sump) and would like to know your thoughts on weirs. So the tank I have now is a Herbie style with a lower standpipe as the main drain (raised to about about 10 inches above the bottom of the tank) and a durso style as...

I'm in the process of setting up my first saltwater tank. It's a 60 Gal cube with a custom 20G High as a sump. I'm finally at the stage of leak testing my plumbing. However, I can't get it to maintain a consistent water level in the overflow box. I'm using a Herbie overflow and can't seem to...

So I purchased the h2overflow and stealth box and finally got it set up using the herbie method with a small trickle of water going into the emergency overflow, I do not know what the issue is but it is pretty loud I got the tornado effect on my main line I think that’s causing the issue but I...

Please help with overflow water level... Starting to plumb my new 50 gallon cube (my first sump system tank). The emergency drain height (Herbie-style overflow), as it came pre-cut with my SCA aquarium system would put the overflow water level at 4” below the bottom of the weir slits. Is this...

So here is the thing I am currently new and plumbing my first tank. I am doing a Herbie overflow because that seems to be what fits on a tank that has 2 bulkheads. Essentially I have a sump with 2 filter socks and outlets to get plumbed to those filter socks. What I am trying to do is maximize...

If you use a Herbie drain system in your overflow do trickle into the emergency standpipe or keep it dry? Why? I've read a lot of stuff that says to keep a slight trickle going down the emergency standpipe, but don't let it create a siphon. I'm trying to understand why we would even bother to...

Anyone using 1.5 inch drain lines on Herbie type drain systems ???

I have been running a 120 gallon reef-ready reef tank for the past 6 years. For all of this time I have been running with the drain kit that can be bought in addition to the tank. I have switched up the plumbing underneath the tank multiple times but it has always been one durso in each...

Back to the drawing board! Everything great for 4 days after starting the cycle, then noticed the full siphon line making a lot of noise empting into the sump this morning (Herbie style drain). Further inspection showed the noise was from a lot of air in the line causing bubbles to be...
