open pipe did no harm it had remained undiscovered for years.
The cause of the trouble was a plumber whom the defendant called
in to do some work at the other shop, that is, the shop next but one
from the plaintiffs place of business. He found it desirable to
turn off the water in that shop, and in looking for the stopcock to
do so he tried two which he found further up the street. One of
these proved to be the old stopcock of the open pipe. He turned
it on without any immediately apparent result and then for some
reason failed to turn it off again. As a consequence water flowed
into the defendant's premises for some considerable time. This
omission on the part of the plumber might well be found to be
negligent, but he was an independent contractor and not a servant
of the defendant. His negligence. however, would not have brought
about the damage if it had not been that the pipe was unsealed
and there was no valve except the stopcock in the pavement. A
pipe in such a condition involved an unnecessary risk to the property
of the adjoining occupiers, because it left their safety from flooding
to depend on the closed valve of the stopcock in the street, which
in the course of time someone was not unlikely to open, whether
from mischief, thoughtlessness or mistake. Indeed, the by-laws of
the water authority appear to require precautions greater than the
shutting of the stopcock: See by-law 86, cll. 40 and 43, N.S.IW.
Rules, Regulations and By-laws, vol. 17 (1928), pp. 143, 144. There
are, therefore, two independent points at which fault occurred, viz..
the improper condition in which the pipe was left when the service
was disconnected and the negligent omission of the plumber to close
the stopcock he had mistakenly opened.
