A straight one (Fig. 38B.) made to screw into an iron socket or length of gas-pipe, will be found very handy for getting dents out of long lengths of soil-pipe. ❋ Various (N/A)
He described tersely the essentials of good plumbing, the necessity of a trap on the house drain, the ventilation of the soil-pipe, and the ventilation of the trap against siphonage. ❋ Various (N/A)
It is usual in modern plumbing to relieve the pressure of gas in the soil-pipe by what is called a "stench-pipe." ❋ Unknown (1865)
If the soil-pipe is open at its upper end this expansion will be at once relieved; but if the top of the pipe be closed there will always be danger of the forcing of the feeble barrier offered by the ordinary water-seal trap of a branch pipe leading from a wash-basin or sink. ❋ Unknown (1865)
No matter what amount of water may be used for flushing out the soil-pipe, its sides will always be more or less coated with organic filth; and, however slight this coating, there will be a certain amount of decomposition. ❋ Unknown (1865)
If water-closets are used, the soil-pipe should deliver into the drain between the flush-tank and the settling basin. ❋ Unknown (1865)
This is a pipe from one to two inches in diameter, leading from the highest point of the soil-pipe to the outside of the roof, where it is bent over to prevent the entrance of foreign matter, or is closed at the top and perforated with holes to allow the gas to escape. ❋ Unknown (1865)
What is said above concerning the ventilation of the soil-pipe from end to end relates to the interest of the private owner. ❋ Unknown (1865)
The soil-pipe, carrying the discharge of water-closets, should not be delivered into the flush-tank, but at a point farther down the drain, so that any solid matter it may deposit shall be swept forward by the next action of the flush-tank. ❋ Unknown (1865)
The settling basin should be constructed as shown in Figure 9; and this, as well as the flush-tank, the soil-pipe, and the connecting drains, should be amply ventilated. ❋ Unknown (1865)
The arrangement of the soil-pipe here indicated, although excellent and efficient, is susceptible of further improvement by the use of a ventilating cowl or hood at its top. ❋ Unknown (1865)
If the soil-pipe is closed at its top, or if it is obstructed by a trap in the lower part of its course, there can be no such circulation of air as safety requires. ❋ Unknown (1865)
There should be no trap in the soil-pipe, and no trap in a private drain between the outlet of the soil-pipe and the sewer. ❋ Unknown (1865)
Then, too, the sealing-water of the trap readily absorbs any foul gases presented at its outer end, toward the soil-pipe, and gives it off in an unchanged condition at the inner or house end. ❋ Unknown (1865)
The gases formed by the decomposition of organic matter in the sewer itself, or in the soil-pipe, have a certain expansive force which is greatly increased by the elevation of temperature, caused, for example, by the discharge of hot water into the pipe or sewer. ❋ Unknown (1865)
The soil-pipe should be of cast iron, carefully jointed with lead, not less than four inches in diameter, and carried by the straightest course possible up through the roof and generally higher than the ridge-pole. ❋ Unknown (1865)
Water-seal traps which are unused for any considerable time are emptied by evaporation, and thus open a channel through which the air of the soil-pipe may find its way into the house. ❋ Unknown (1865)
If there is an opportunity for the free admission of air from the well-ventilated sewer to feed the upward current almost constantly prevailing in a soil-pipe open at both ends, the gases resulting from the decomposition will be of a different and less injurious character than where the air is confined, -- and by the mere volume of air passing through the pipe they will be so diluted that even were they originally poisonous their power for harm will be lessened. ❋ Unknown (1865)
