PRELIMINARY DESIGN

ANALYSIS:

(3 SOIL STACK PIPE)

ADVANTAGES:

1.) IDEAL DESIGN

2.) ONE STACK, ONE BRANCH

SMALLER DIAMETER OF PIPE

3.) EFFICIENT DESIGN

4.) EXCELLENT IN CASE OF

REPAIR

DISADVANTAGE:

1.) NOT ECONOMICAL

MORE STACK PIPE

MATERIALS

TO BE USED


9/29

PRELIMINARY DESIGN ANALYSIS:

(2 SOIL STACK PIPE)

ADVANTAGES:

1.) IDEAL DESIGN

2 SOIL STACK PIPE BUT SMALLER

DIAMETER

(VS FOR MAINTENANCE & REPAIR)

DISADVANTAGE:

1.) PRACTICAL BUT NOT

ECONOMICAL

1 SOIL STACK FOR MALE

1 SOIL STOCK FOR FEMALE

(STACK PIPE CROSS ES TO THE

CR WINDOWS)

PRELIMINARY DESIGN

ANALYSIS:

ADVANTAGES:

1.) IDEAL DESIGN

1 SOIL STACK PIPE

2.) ECONOMICAL & PRACTICAL

DISADVANTAGE:

1.) MIGHT EXCEED THE

MINIMUM

FIXTURE UNIT PER BRANCH

2.) LONGER HORIZONTAL

DEVELOPMENT LENGTH

ONE BIGGER DIAMETER SOIL

STACK PIPE

SUMMARY:

DESIGN CONSIDERATIONS:

ECONOMICAL

SIMPLE & EASY MAINTENANCE

INITIAL CONCEPT:

ONE MAIN SOIL & VENT STACK @ LEFT WING

AND

ONE MAIN SOIL & VENT STACK @ RIGHT WING

B. Sanitary DrainThe sanitary facilities consist of well

designed plumbing system and with the useof materials conforming to the specificationprescribe in ASTM.

a. The design is to install one (1)main stack assembly, soil eachwing.

b. The design is to install one (1)main stack vent each wing.

stack and vent stack to insure `atmospheric air circulation in thePlumbing System.

b. All plumbing fixtures will beprovided with appropriate &applicable installation of ventsystems: unit, relief vent and

loop vent, wet, individual, etc.c. Horizontal pipe installation is

to slope but not less than two(2) percent or more than four (4)percent.

d. All Fixtures are to beprovided with P-trap except

water closet.
