Herbie Question

[Makede]

So from several of the write-ups of the herbie system I have read they suggest submerging both the siphon and e-drain about 1" under water in the sump. Can I run these lines straight down? As in, no 45's or 90's just 100% straight from the overflow to the sump? Obviously with a gate valve to adjust the flow.

Not sure it matters but both are 1" drains.

Thanks!

I keep the emergency drain out of the water.
Makes a loud racket this way letting you know something is not right.

Will my main drain is 3/4" and my emergency drain is 1" , the main is lower than the emergency by 1" almost and all my elbows are 45's.. I think and I had a major discussion with ither reefers about it and almost everyone agreed that the more your drain are straight the better, because you want you overflow drain ti be as smooth as possible to get to you sump area. The 90 degre angles has it's downs of clotting or anything can easly stuck inside it. That's my own openione and others might disagree

Due to the locations of my overflows (( dual RR overflow )) and the location of inflow holes of my sump, I have both 45s and 90s on my drains (( both main and E )). Been running for 4 months now, and now issues.

The main drains are about 1" under the water level of the sump (( filter socks )) and the E drains are at the water level, using an 90 and an 45, I can still hear if the water is going down them, but the splashing is lessened.

The left side, I might have been able to fit an 45 for the last part of the main drain, but was fed up with plumbing. Can also see the right sides main drain coming into the sump, gate valve is on the other side.

The lefts E drain (( added more PVC to get it to the water level )) and the right's main drain (( below that is the return ))

The right's E drain -- again was lowered right to the water level. (( Ignore the APEX, was spacing out things, it doesn't sit on the sump. ))
