Plumbing Question

[shollis2814]

Working on plumbing (or planning to plumb) my first drilled tank. It's a 33-long and will eventually have a 20-long sump, but now it's just an old RedSea Bioball type 5-gallon sump.

I'm using an Eshopps S ghost overflow. My question is, should I leave it at 1" for drain plumbing, or step down to 3/4"? Noise reduction is pretty important to the wife because of it's location. I do plan on using threaded unions and a gate valve since we will be moving sometime down the road and I'd like to build with that in mind.

My return pump is a submersible 400gph one that I have used on a 36 bowfront with sump with no issues, if that matters.

Thanks!

I would leave it, theres no REAL benefit to shrinking the drain size aside from maybe saving a few bucks on the fittings and valves. Either will work though so it's really up to you at the end of the day. :) as far as noise goes, make sure your gate valve is as close to the sump as possible and the main siphon goes a good 2-4 inches under the waterline in the sump

Thanks for the response. By main Siphon do you mean the main drain from the ghost overflow?

I hadn't thought of that, but if I plumb that one below the waterline and the emergency overflow closer to the surface, then that might be a good warning sign. More noise means the emergency overflow might have kicked in.

Does that sound...sound? :-D

That's what I mean yes :)

And it sounds sound indeed, this is typically how they are plumbed I would actually plumb the secondary/emergency drain JUST over the waterline. This will prevent the Trickle from the regular operation from being noisy but will create a lot of noise if a bunch of flow is pouring down it indicating that your main siphon/drain is clogged.
