Plumbing...you knew it was coming...

[Mark...]

I'm working on the plumbing design and parts list for my DT down to my basement sump.

I have some questions,

I plan on going Herbie with full siphon and dry emergency. The central overflow came with two 1 inch bulkheads and two 1/2 return bulkheads. In-regard to the drains is there any advantage of going 1.5 inch pipe before (overflow) and after the bulkheads.

On the return, I was planning of running 1.5 inch (pump use 1.5 inch output), up under the tank and whey it off to two 3/4 inch before and after the 1/2 return bulkhead.

Does the narrow bulkheads defeat the larger pipe?

Drain gate valve upstairs under tank or in basement just before sump? Used to dial in flow.

Does this sound reasonable?

Thanks

Another question...what is the name of the fitting used to reduce from a 1 inch ball valve to a 1/2 inch tube to feed a GFO canister.

If it's a BRS reactor you would use a 1" slip x 1/2" thread reducer bushing and a 1/2" thread x 1/2" push connect (also called a john guest fitting sometimes).

Thanks! If anyone has any info on my overflow and return question I'd appreciate it.

Don't see the point of increasing after the bulkhead and before. If I can opine. I would just take the 1.5 inch pipe to the bulkhead and reduce it there to 1/2 inch and continue with 1/2" throughout the return. KISS method but should work. or swap the bulkhead for 3/4 (assuming non-tempered) and run it through

Thanks for the input.

Where would you put the drain gate valve? Under the stand or down in the basement just before the sump?

Since its being used to adjust the display. I would put under stand. So you can see whats happening, instead of adjusting and then having to run up the stairs to see each adjustment

That's what I was thinking, but I saw mention of some down by the sump. Thanks for confirming.

Just out of curiosity, why are you using the drain line to regulate tank flow? Shouldn't you be restricting the return flow? Personally, I would never to anything to restrict the drain. Flow rates change over time and that just sounds like it could lead to an overflow in your display.

You do not need to reduce the return line, they just go over the side of the tank and in... (in a Herbie style)
The gate valve is more effective the closer you get to the sump.

The Herbie (silent) flow method relies on a full siphon (totally under water) that needs a gate valve to adjust the flow. It's designed with a dry emergency drain as a backup to prevent any overflow situations. Its extremely safe. The return pump will have a ball valve for adjustment back to the tank as well.

And while I have your attention, when setting up water flow to a refugium, do you feed it from the return side or the drain side? My pump will be in the center of the sump with the rufug to the right.

Thanks!

Fuges are normally fed with the drain line.

You will be using the 3/4 as your full siphon correct? I assume the bulkhead is 3/4 and not 1/2 as you posted. If you want an opinion on setting up a herbie maybe Sunny could chime in, and post a pic or 2.
