Sump Plumbing question

[CANAMONSTER]

I don't have very much experience with sumps and this is my own first sump.

Is it NOT ideal to have different lengths for the overflow drains pipes that go to the sump?

Where the location of my sump is in accordance to my drain holes, one pipe will be a little longer maybe 6 to 8 inch. Same bends just a little longer. How will the affect me?

short of slightly lower flow from that pipe it shouldn't make a big difference.

I think you're fine. It's the height in the tank that really matters.

Technically, it will flow a tiny bit less due to the extra length and bends but it won't be anything noticeable.

You'll be fine I have two drains at different lengths since my sump is in the middle but my inlets are towards one side. Not a big deal I have a foot or two extra length but never noticed anything and its been a decade. Just make sure you test the sump with a power outage. Let it run for a few minutes and turn everything off and see where the level goes.

People forget to do that and they get tons of water overflow from their sump. When my power goes off I have about 6" in the sump still at full capacity.

Good point above. Also, you'll want to make sure there's no back siphon and/or have some mitigation to reduce or avoid over filling the sump when the return pump is off.

Yes but most overflows will have this unless it's a diy one you have to drill a hole and with an air tube or just leave it with a small hole at the top of the overflow. It will siphon back when the pump starts to work again so it's crucial to have everything tested beforehand

I couldn't infer from the post that the OP had a return that set-up with siphon break and/or check valve to avoid backflow? Many custom overflow won't have this unless all the plumbing was provided. Moreover, this is a moot point if the returns were submerged and OP didn't know about it - so I didn't want to speculate.

But yes, the point here is testing the drains AND returns for when the return pump is OFF - whether power outages or intentional.

Lots of room in the sump fellas, I have a overflow flow box
