This document provides information about plumbing systems, including: - The water distribution system conveys water through pipes and fittings to sanitary installations, which carry off wastes. - Clean water lines are represented by a visible line and two dashes on plans, while sanitary lines use a bold continuous line. Fixtures have common symbols and storm drainage uses two invisible parallel lines. - Procedures for laying out a plumbing system in a floor plan include indicating fixture locations, drawing water line connections from the source, detailing pipe fittings and fixtures, specifying materials, and adding a legend.

18. Procedures to lay-out the
plumbing system in the
floor plan.

19. 1. Indicate the location of water
fixtures by drawing their symbols on
the place you think is the most
suitable location for each. You too,
shall indicate the water supply source
from the street water branch.

21. 2. After locating and indicating the location
of the fixtures, draw the water line
connection from the water source. In
addition, try to indicate the position of the
water meter and the check valve based
on their layout and the source of water
supply.

23. 3. Draw the water line layout of the pipe
fittings and the fixtures to show the
different kinds of fittings use, and write
down the specifications of the material
used.

25. 4. Indicate by writing down the material
used for the pipe and fittings.
5. After doing number 4, Darken the water
layout and write down the abbreviations
on the fixtures together with the legend to
distinguish the different water fixtures.
