Hello all
just in the process of installing a water curtain feature
its about 2.5 metres to the top from the pump below
what size / flow rate pump should i get to ensure a reasonable flow
im not wanting a raging torrent....
Thanks.

Interesting feature. How is the water distributed, how wide is it, and what size pipe are you using?
