LOCAL BOARD OF HEALTH
SEWER GAS & HOUSE DRAIN VENTILATION.
The Local Board of Health begs to call the serious attention
of the inhabitants of Tottenham to the great importance of
House Drain Ventilation. This is recommended by the
Government and all other Sanitary authorities as the only
means (when coupled with effective trapping) of entirely
keeping out of Houses dangerous sewer gases. Those gases
which are harmless when they escape freely into the open air
are known to be the frequent cause of serious and even fatal
illness when they find their way into the interior of dwelling
houses.
The soil pipe of every water-closet should be ventilated
by means of a pipe from it carried upwards outside the house
until it is clear of the eaves.
The sink-pipe and the waste-pipe from basins and baths can
be ventilated in the same way, but in these cases a still better
and cheaper plan of keeping out sewer gas is usually possible.
This is to sever the pipes outside the House, and to place a
trap below the point of severance. Overflow pipes from
cisterns and baths should never enter the sewer, but should
always end in the open air.
When it can possibly be avoided, no pipe issuing from
the house (except the closet soil-pipe) should pass into the
sewer without a break. Rain-water pipes should never be
used for the purpose of ventilating drains.
House-drain ventilation can be carried out at a moderate
cost. Further information can be obtained at the Board's
Offices.
By order of the Board,
EDWARD CROWNE,
CLERK.
