have just moved and the water presure is 30-35. is this ok to run the merlin or will i need a boaster pump.  before the pressure was 40-45psi. 

i have a 650L ibc tank for storage and use 350L per day so not in a hurry to fill just worried it might damage the merlin at such a low pressure.    also not on a meter ( yippe ) so not too worried about watse   cheers

You will need a booster pump.  The Merlin's minimum operating pressure is 45 psi.

alex  ,will it damage the ro though or just produce at a slower rate as it been running on 40psi for the last 6mths

It will not damage the Merlin it will just produce less efficiently and the product will not be as pure.
