| Can't say without knowing the : 1. street pressure 2.the developed length of the pipe from the street to the farthest fixture. 3. Total number of all fixtures in house. (What? No laundry? How many sinks in baths?How many shower heads in showers?) 4. Plans for any future development like lawn sprinklers, baths, fire-sprinkler systems, etc... Please provide. |

| I came up with 22.2 water supply fixture units for the current load on the system. Presuming a 50psi water pressure at the pump, and a 60 ft maximum developed length of pipe to the furthest fixture, the Tables from the IRC/IPC require a minimum of a 3/4" to 1" distribution pipe branches to all fixture groups with 1/2" pipe to individual fixtures. Other codes or methods of determining the load may vary. |
