Remote sump on the same floor

[Dine]

I have a room off my garage that I’d like to setup as a fish room (currently houses the breaker box and hotwater heater. The room is climate controlled. If it’s possible I’d like to run a remote sump to this room. The room is on the same floor as the DT. I can easily plumb through the wall to get into the garage BUT I would have to Route it to the floor to go “under” a door (slight step up to go from garage to house) then back up to drain into the sump. The plumping would never go higher then the DTs drain. Would this work? Is it safe?

What kind if height difference would there be between the water level in the tank and the water level in the sump?

About the same as a typical under tank setup. Would put the sump on the floor just like I would under the tank just in a different room. If it was 5ft over I wouldn’t question it. But it would be a bit further then that...

I wouldn't be super worried about it myself but some pictures of how you plan on running the plumbing might help to get a better picture of things...

Ok. Here goes. Pardon the mess. Finishing up another project.

1.this is wherethe DT is going
2.through the wall behind the sink
3.this is the garage behind that bathroom
4.runs along the ground
5-6Under the door
7. Has to come back up to dump into the sump but if the sumps on the ground would never go above the DT drain height

My build is actually similar.....obviously the greater the height difference the better off you will be. There is actually a formula somewhere that shows the required height difference per 3 feet (or something like that) for the water to continue to drain. My sump sits on the same floor and is roughly 18 feet away and I don't have any issues. Just make sure you use a level on every couple of feet of pipe to make sure it is heading in the right direction.

Any pics of your setup. Your build thread link had an error? Any idea where that formula is?

I snapped a few quick pics.....hard to tell how much the two drain lines increase in height but hopefully this helps. I also did a quick plumbing google search and it says that the standard slope for drainage is at least 1/4" per foot......I think I am well below that though and mine still drains fine.

Thinking about the physics of flow and water resistance, resistance is proportionate to length / radius ^4... so my advice would be to get pipe of the absolute maximum diameter/radius/width to minimize flow resistance.

The second thingthat occurs to me is the trade off between redundancy in the case of blockage vs only having the space for one large diameter drain and another return line. Than at tidal gardens recently did a video showing how they rigged the traditional 3 drain overflow into a single large diameter pipe with a long length into their sump across the barn. I think you should check it out for ideas.

so I’m prob closer to 30ft of actual pipe (rounded up). That’s the part that makes me think it’s just too far to run it.

Thank you! That’s quite the setup. Running one single large pipe would actually make plumping it so much easier. Little scary to imagine one pipe but I guess @ 3”.....
