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.
