Frequent use of plumbing fixtures contributes to safety. It causes a large volume of water to pass through the pipes. The flushing of the pipes and drains in this way makes them cleaner and thus safer. It is frequently said by those who have plumbing fixtures in their houses that they use them as little as possible, because they are afraid of them. Nothing worse could be done. The water in the traps evaporates or becomes foul, and thus the gas has a free entrance to the house. A water-closet helps greatly to cleanse the soil pipe and outside drain. It discharges a large volume of water into it suddenly, in a way to keep it clean. It is not a bad plan to use the closet at least once a day, solely for the purpose of flushing the drain. In houses where there are a number of wash-stands distributed through the various chambers and halls there is danger from neglect in using them. The water seal in the traps may evaporate, and thus give direct sewer-air connection with the house. Particularly is this so in the guest’s room. A wash-stand is a more dangerous fixture for this reason than any other in the house.

The water-closet problem has received a great deal of attention. A few years ago they were quite complicated, there being levers and pipes, pans, springs and weights, to a degree of complexity which caused a great deal of trouble. There has since been a return to first principles and great simplicity. The water-closet of to-day is nothing more or less than a large bowl connected by means of an “S” trap four inches in diameter with the soil pipe, and provided with means of flushing with large volumes of water. Such a closet is known as the “washout closet.” In other closets there is an intermediate plunger-valve separating the hopper from the trap. The plunger-valve is defined by its name. It is a large stopper which plunges into and closes up the opening to the trap by means of its own weight when released. That which makes one closet different from another has to do more with means of flushing than anything else. By flushing is meant the pouring into and distribution of water in the hopper. The most popular closets, those which have given the most satisfaction, are “washout” closets, made entirely of white earthenware, not alone the bowl, but the trap and connecting neck. Closets are best flushed from an independent tank, which is placed about seven feet above the closet and connects with it by means of 1¼-inch pipe. The height gives it a strong flush of water, which cleanses it thoroughly.

In the past it has been usual to conceal the earthenware or iron body of the closet. It is best to leave it entirely open around the sides, that the entire apparatus may be exposed. Sometimes it is necessary to support the flap and seat by legs, though the modern closets are arranged so that all of the woodwork may be secured to the upper part of the hopper or the wall. There should be the solid flap covering to the wooden seat with the opening in it, both of which should be hinged, so as to allow them to be thrown back. It is convenient to use the water-closet as a slop hopper. In order to do this the seat should be hinged, so that it may be thrown back out of the way.

One frequently hears it said by those who exercise their authority over household matters that they do not allow anything to be put into the water-closet except that which is naturally intended for it; meaning that they do not allow the slop water to be put into it. There is no reason in this. The closet that cannot be used for this purpose cannot, with safety, be allowed in the house. The use of the water-closet as a slop sink is not only legitimate but desirable. It flushes the drain.

There is a movement toward simplicity in general plumbing apparatus. At the time the water-closets were in the complicated state mentioned, everything pertaining to plumbing was in the same general condition. It was thought necessary to fill a house with a wilderness of pipes and traps to have it safe or satisfactory. The very complexity of the arrangement made it not only unsafe but expensive to maintain.

We have all heard a great deal about the expense of maintaining a plumbing plant, if it may be so called. There is no reason why there should be constant repairs and expense. It is pleasant to know that additional expense is not necessary to secure immunity from trouble. The idea of simplicity in arrangement, general excellence in the fixtures, material, and labor, which go to form the completed work, has to be borne in mind. The arrangement of the plumbing apparatus has to be planned with the same care and thoughtfulness as the other parts of the house.

It should be remembered that if the pipes are placed in a position where the temperature is liable to fall below thirty-two degrees the water in the pipes will freeze. Thus it is suggested that all pipes should be on an inside wall,—if possible, next to the kitchen flue,—and that there be here arranged an especial pipe duct of wood to ventilate the kitchen, and, at the same time, keep the pipes from freezing by means of the warm air which will pass through it. This duct should be covered on the face with a wide board, which can be readily removed by taking out a few screws. Thus the pipes may be exposed at any time desirable.

If the hot-water boiler in the kitchen is surrounded by an enclosure which has an opening in the bottom, and which connects from above with the pipe duct previously described, there will be a current of warm air passing upward through the pipe duct as long as there is warm water in the boiler. The water in the boiler will be warm long after everything else is cold. This will insure safety from freezing when other helps fail.
