2” drain for two tanks into one sump???

[mrleojr22]

So I’m plumbing in two tanks into one sump I’m building In my basement. A 90 gallon tank and a 40 gallon breeder. They both have two 1” drain lines i was planning on hooking them up into a 2” drain for both tanks to head into my sump. The sump is a 60g breeder. Does that sound like a good idea?

I think the worst thing that could happen would be that the drains might be noisy with the air in the 2" if you really tried to push a lot of water. The 2" is really oversized so my guess it that it would work fine as a low flow gravity drain. It really depends on if you tried to push enough water through the 2" to make it gurgle. I tend to doubt that would happen from a 90 and 40 gallon set-up with a basement sump. You should try to avoid any long horizontal runs on the 2" if possible.

She's probably gonna be noisy!

If there is only 2 one inch drains, you can join them, BUT, you'll need to get a gate valve and put it on the larger pipe near the sump. This will ensure you get the pipe full of water and the drain is as quiet as possible. If you put drains on each smaller pipe up near the tank, then as soon as the water passes the pipe it will mix with air, and you'll get some noise. Add in more air when it gets to the larger pipe, and you'll probably have a good amount of noise.

If you absolutely want to combine the drains, combine the full siphon drains to the same pipe, and put a gate valve near the sump. Then combine the emergency drains on a separate pipe, and run that to the sump as well.

I don’t see how this will work. Without gate valves on each 1 inch pipe, it will be impossible to fine tune the water level in the overflow and there will be noise without full siphon on the main drain or more than a trickle through the backup

Can you join Main drain to emergency on each tank and then join it to a single drain? I re-read first post...you have 4 1 inch pipes going into a 2 inch... i thought it was 2 1 inch into a 2 inch.

I'm no plumbing expert, so you may need both. I'm just not a fan of having the gate valve, then large runs of pipe, then upsizing the pipe, it's just asking to be noisy.

I agree with you, just think you need both
