Overflow

[jdivz87]

In my overflow box I had the emergency and main. But the main was louder than it should. A friend of mine said I can replace the pipe with a strainer as in the picture and once I did that the level went up and down in my overflow. When the water goes up to emergency and flows in it’s dead silent but isn’t that just for emergencies…. Or is it okay that it’s slightly flowing into the emergency drain…… when it goes lower you hear the water from the box inside tank overflowing into the overflow. Adjusted gate valve and return pump and it just keeps going up and down. Should I just cut the pipe that was originally there shorter then add the strainer then put it in?

help

Yes it’s ok to have a bit going down the secondary. That’s the way it’s supposed to be. You don’t have an emergency. You have a primary, and a secondary. If you had a third drain pipe you’d have an emergency

 

[jdivz87]

I do and adjusted that and the return….
I did this (second picture) and it’s leveled off but just makes a little nose

When I have no Strainer you can hear the siphon

Water is getting organized and funneling. The strainer interrupts the water getting organized, and there’s no harm. Many people use two elbows to get the main drain intake to face down. Like this

Oh shoot! Does this silence it???

Your pictures in 1st post is right. If there is gurgling noise still there, you can open the gate valve a 1/4 turn. But you want a slight trickle down the higher pipe.

The second set if pictures, the gate is too far open.

So it’s okay for the water to be going down my “emergency” or so I thought it was… it’s the herbie. A main drain and an emergency that doesn’t get used

Most of us that run a Herbie don't have the second drain dry. It's possible, but very difficult to to get it tuned that way. You also don't get any surface skimming with the secondary dry.

So essentially that pic I sent where a small amount is going into the sump and it’s dead silent is okay and safe to have it that way?

Either the u shape as suggested or at least 4 inches between the pipes.

By 4” between pipes you mean?

 

[Dburr1014]

Higher; lower
Syphone swirl will be about 3"+/- deep. If it gets to the lower full syphone pipe... Sucking sounds, maybe syphone break.
Lower pipe, if no u shape, needs to be lower than trickle pipe to overcome this. About 4" +/-

Lol going to decipher this message haha I suck at math lol. I’m a visual guy

Does this help?

 

[jdivz87]

That’s perfect!!!!!! That’s how my first picture is basically!
Reason I was so confused is because that “trickle” you have. Every video I’ve watched says that’s the emergency drain and should be dry … but when I did the method you did in your amazing pic lol it was dead silent, but water was trickling/flowing into that so called “emergency drain”

 

[jdivz87]

I’m heading home. I’m going to show you what I have now. It’s quieter but not dead silent like when I had the “trickle” into the “emergency drain”

Yes with a herbie, you need to have a trickle in the emergency. You also have to adjust it time to time. For instance, I feed flake food time to time, goes in the weir and into the drain. Eventually, it may slow the drain, gets more water in the emergency, which means noisier than normal. All I do is open the gate valve for a split second, close it to where I was about and watch my bubbles coming out the emergency. If their to many, open the valve a tiny bit. No bubbles, close the valve a tiny bit. I only want to see just a few.

Your 1st pics where a trickle is going down the tall pipe, yes.
