Hi all, I recently bought a van with a wfp system already in it, ive gone to use it today and the water is not good. I dont know if its set up correctly, the mains water goes into the merlin r/o unit and comes out at about 180, it then goes through a small white block which then comes out at about 145, and then the resin tank with an end result of about 110. Can anyone give me some advice on what i need to do please, would be much appreciated. Cheers
