Excerpt from Sewer Gas, and How to Keep It Out of Houses: A Handbook on House Drainage My chief object in writing on this subject' was to suggest a plan for preventing the evil which is now causing so much alarm - viz. The back-flow of gas into our houses. Of this plan I have now had four years' experience and have, without exception, found it to answer perfectly. In the first place, I applied it to my own house at a cost of fifty shillings or thereabouts. This house is of the ordinary type, and is drained into a foul sewer. Before the introduction of the new plan, it was never free from smells; while, since, there has been no annoyance of the kind, nor have the drains required any attention whatever. The plan is very simple, and can be applied to any fairly-drained house at a small cost, and without requiring the drains inside the house to be disturbed.
