Bottom drains

[Cdsdave]

I currently have a Tetra 3" bottom drain. I am going to do an addition to my pond and am in the market for another drain. For cost reasons and ordering simplicity I am considering a Rhino 1 3" drain. Has anyone here used this brand and if so what's your opinion? Does anyone have another brand favorite in the 3" size?

Thanks in advance

I make my own so no opinion on brands. Never heard anything bad about Rhino.
