How much waste should come out of a merlin when i switch mine on seems that just the same amount waste as the good stuff came out?  ive got a lever on there to slow it down but dont think thats good for the merlin?

Dont know the Merlin that well, but normally if you restrict the waste water outlet, then there will be a gradual build up on the Membrane Inside Housing which will reduce the life of the Membrane. The better solution is to buy and fit a Booster pump, the increased Input pressure will produce better/lower TDS values and reduce the waste water procentage. Terry
