ROs still confuse me but looks like a cracking system 👍

[@DavesKoiPond]

Thanks, 🙂
If I only had unlimited tapwater like a welsh mountain stream, I wouldn't need it at all lol 😄
It just helps to reduce the hardness, nitrates, metals ect... in my pond water,
and significantly reduces the amount of tapwater I need to use. 👍

Interesting as ever Dave, ever felt the need for flow restrictors?, chap I've been following in India uses them, but sometimes very difficult to understand him.

[@DavesKoiPond]

Cheers mate, 👍
Flow restrictors, do you mean on the waste outlet instead of a needle wheel valve?
Only if i'm using standard mains fed RO and you want the usual 3:1 or 2:1 effluent to permeate rejection rate.
Recycle RO waste out, needs to be adjustable depending on final TDS to prevent excessive membrane fouling. 🙂
