Ventilation OF Sewer.


The prevention OF disease arising
from sewer gas can only be accomplish.
cd by obedienee 70 the following sani.
tary rsquirsments;
A trap should be placed ON every
main drain TO disconnect the house from
The sewer or cesspool. This trap should
have seal Of not less than one and A
halt inches, aud be furnished with A
hand hole Tor convenience In cleaning
II stopped from any cause; while N the
rain water down.spout Is connected
WIN the sewer Just above the trap,
great assistance will he rendered in pre-.
venting deposits, Every house drain
should have an inlet for fresh air enter.
ing at q point inside the main trap and
csrried to a convenient location out of
doors, not too near Windows" For the
latter reason the down.spout selected
must be one running to the caves of
the main building aud not stopping at
the piazza or any lower point. Every
vertical soil or waste pipe should be ex.
tended at least iull size through the
roof, not less than four feet, aud sur
mounted with a plain yentilating cap of
such form as not 10 Obstruct the exit of
air.
No trap should be put at the loot of
vertical soil pipes To impede circulation.
Traps should he placed under all sinks,
baths, basins, wash trays, water closets
and other fixtures and ~ near 10 them
as possible. All traps under fixtures
should he separately ventilated, in or.
der tn guard against siphonago; such
vent pipes should not branch into soil
pipe below where any drainage enters
70, but always above, and in some cases
Il Is pJelaraple 10 carry them to outer AIR
Independently. Ii the ventilation or
traps under the kitchen or basement
sinks be impracticable the discharge
pipe below should bs one-hali inch
greater IN diameter than the trap aud
piue above.
The safe, waste and refrigerator pipes
and tank overflow pipe should not un-
der any circumstances be- run into any
drain or soil pipe hut discharged indie
pendently into an open sink or bowl, so
that the connection with the sewer
shall be completely cut off,
Water-Closets should not be supplied
directly from street pressure or by pipes
from which branches are taken Tor
drinking water.
No drain should be constructed under
a dwelling house except where absolute
ly necessary, aud then IL should be OF
cast iron, with tight joints and ventilat-
ell at both ends. All drain pipes within
a house should be of metal, the soil
pipes ct cast iron, other pipes Of lead ;
under no circumstances Is the use oi
cement or earthenware permissible.
The joints of cast iron pipes should he
filled with melted lead aud properly
calked. The union of lead with iron
pipes should be- made by means III a
sOldered brass ierrule, or cast iron
sleeve; ia the latter case the lead pipe
put through turned over 1t, and the Ter
rule or sleeve inserted in the hub aud
loaded ia tho usual manner. such
Joints should not be made with putty OF
cement.
A not uncommon method ut ventila.
ton is tO connect the main drain with
the kitchen chimney; with tho cold AIT
inlet this gives a circulation OF fresh All
ia the lover drain while the chimney
remains heated, otherwise Il Is a source
Of danger, but at its best, il is no assist
ance tn the vertical pipes, which cannot
be ventilated or guarded against siphon'
age, except by carrying out at the ROOF
iull.si1s and yentilatlng the traps a.
directed.
These requirements all apply with
equal force to connections with cess.
pools. Aud where these are used, they
should be ventilated at the cesspool III
addition.
