Are weirs necessary?

[Beanbone]

Hi

I'm in the process of building a pond less waterfall. I'm wondering if weirs are really necessary. I would like to create a natural effect with water "weeping" and pouring from a dry stack retaining wall. Ideally, I'd like to split the flow from the pipe behind the wall, and let the water emerge where it wants into a basin below the retaining wall. Of course, lining would be under everything to avoid water loss.

My plan is to split with a Y adapter or two and have water pumping directly out of tubes.

Curious to hear if anyone thinks this will create.

My waterfall will be 1200 gph

Welcome to the forum
running out of the tubes will be fine

Thanks. Any recommendations on tube brands? I've heard horror stories on corrugated PVC splitting

This is great. Thank you. Did you the rigid PVC directly from the pump with elbows?

And than you for the warm welcome!
