Have you flushed it (you need to do this for at least an hour) then run it for another hour then check it will come down. Even more over the coming days, thats what mine have done anyway!

Regular flushing is much more important then doing it once a week for an hour. For every fill flush it for 10min. This also helps get the air out of the membrane, membranes which are not wet properly fail.

Is it a new housing? New membrane?
Internal O rings (which seperate waste and feed from pure) can wear and need to be replaced after time.

 >:( >:( >:(

36!!! Thats after over an hour and a half of flushing, and the waste almost maximum, so RO water is just trickling out.

This cant be right surely?

My Merlin with 2 year old filters produces more and better quality  ???
