Hi

My rate is about that and was told it was down to having low water pressure.

I have just order a Merlin, I know it has a high rejection, but is very good RO for the money (220 pounds)

You can easily throttle the waste on a merlin to increase recovery.  Just put a quarter turn valve on the outlet and set the ratio to what you want.

Wouldn't that foul & / or shorten the membrane life

yes it can do but its the same as throttling the waste with a 4040.

obviously you wouldn't throttle it too much, certainly no more than 40% recovery.
