If you are really on the hunt for excellence in the civil engineering field, you are in the correct place. Draining the waste water from a sink was never particularly difficult: any downward sloping pipe would do. But doing it while keeping the smells of the sewer out of the house was the big hurdle.
The same pipes that carried wastewater to the sewer system brought the stench and potentially lethal sewer gases from rotting food, human waste, and other garbage back into the house. For all practical purposes, bad smells kept the outhouse in business and outdoors well into this century. Several thousand years ago, Roman plumbers solved the problem for nobility by directing a steady stream of water through the indoor bathroom they had two and three seaters even!
The stream was a flushing mechanism that washed the waste and smells away. Of course, this luxury required that you lived upstream.
And you quickly became unpopular with the folks immediately downstream! So the idea never caught on. When concern for better sanitation arose in England in the mids, inventors came up with many solutions for blocking sewer gas.
When you filled the low bend in the S-trap with water, it effectively plugged the pipe and prevented sewer gases from flowing back into the house.
The S-trap, invented in the mids, was a big stride toward blocking sewer gases and allowing plumbing to come indoors. Unfortunately, the water seal was often sucked out by the draining water or by other waste that shared a common drainpipe.
Water rushing through the drainpipe created a suction that pulled most of the remaining water along with it. So to restore the water seal, you had to remember to pour a little water down the drain after draining a sink or flushing a toilet to make sure the trap filled. Imagine parents sniffing the air and yelling at their kids to fill the trap! The modern toilet works exactly on this S-trap principle. The drain in the ceramic bowl is molded in the shape of an S-trap.
Once you flush the toilet, the siphoning action effectively sucks out all the waste. Then, while the tank refills, a small amount of water automatically refills the bowl and seals out the sewer gases.
As the slug rapidly dropped, it compressed the air in the pipes below. This sudden compression forced the water seal in the traps of connecting drains back up into their sinks. Then, once passed, the slug often created a suction that tended to siphon the water from traps as well. The solution to the siphoning problem came gradually through trial and error. Finally, a plumber , experimenting with vents in , came up with the solution.
The trick to keeping the water plug in place was to equalize air pressures in the drain system. To do this, plumbers added an extra pipe to the trap that led to open air Fig. C , a kind of pressure relief system. Adding a vent solved the problem of siphoning and kept the water seal in place in the S-trap. The vent tended to collect debris and plug up, however, so the vented S-trap, the standard of the early s, was replaced by the P-trap.
