RO unit are wonderful things but never expect to get teh PGH that they say on the box. ) These GPH are achieved u nder high pressures in tests. Its very rare for a mains supply to give the pressure needed to give the rated GPH for the system. Usually look at the unit and half its GPH to obtain a more realistic GPH rating.
