## Parallel Water Filters Increase Flow Like Parallel ResistorsThe picture below shows how I accomplished the plumbing (equivalent of wiring in an electrical circuit). A couple "T" fittings provided the connection nodes. The water supply can be thought of as the positive terminal of a battery (anode) and the sink's drain can be considered the negative terminal (cathode). Theoretically, if each filter dropped the output pressure by a half, then paralleling two of them should restore pressure to full. Of course if each filter individually only reduced the output pressure to 75%, I would not expect to see an overall gain in pressure above the input pressure (50% increase in this case). Otherwise, I would be able raise the pressure indefinitely simply by adding more filters in parallel. I have a page showing equations on how to calculate series resistors and parallel resistors in electrical circuits.
