    Leaking Internal stop tap with no outside stop tap

    My internal stop tap is leaking and the water company have confirmed that there is no outside stop tap (and that they don't fit them to properties older than 1944). The plumber said that there isn't sufficient height on the internal pipework for it to be frozen. Can anyone help ? Thanks
