Abstract
A sprinkler system primarily intended for use in a domestic dwelling to cover an exit route from the dwelling has an accumulator feeding the pipes leading to the sprinkler heads. The accumulator is charged with water under pressure by a pump drawing water from a water main or from a check tank itself fed with water from the water main. A sterilising unit may be provided to allow sterilisation of the water in the pipework.

11. A sprinkler system comprising:
-
an incoming water source;
a storage tank arranged to receive water from said water source;
an accumulator;
a pump;
pipes connecting the pump with said storage tank and said accumulator whereby the pump draws water from the storage tank and feeds that water under pressure to the accumulator;
a pump;
at least one sprinkler head having an operable valve;
pipework defining a circuit from the accumulator to the tank, said at least one sprinkler head being connected to said pipework; and
a circulating valve disposed in said pipework between the tank and the sprinkler head logically nearest the tank;
whereby a sterilising agent can be introduced into said tank whereafter opening the circulating valve and operating the pump causes water carrying said sterilising agent to flow around the circuit to sterilise the sprinkler system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 23, 24, 25, 27)
