Plumbing works in house use three different systems. First is a sewer system, which consists of disposing waste and sewage water. Second is water supply system, which supplies water to house.Third and last one is venting system. It is the main system, which allows systems to work correctly.The sewage of the house is further categorized into parts, which are usually empty and combine into same sewer. In rural areas, septic tanks are used which do not follow the same rule. The sewage system carries human waste, grey water etc. It is interesting to know that Sewer system does not work without air supply that is why the venting system is always required. These pipes go through the roof of the house or building.Water supply system enters through basement wall of the house or sometimes through the crawl space. There are many water supplies. Most of them are public supplies provided by government or sometimes supplies come from the well. The public or well water supply always carries cold water. The source pipe must be split into two separate parts. One supply provides heating sources for hot water and others provide cold water. When you are replacing or installing supply line for toilet, make sure to install shut off valve for each line. Check the fitting of your pipes as soon as you move in a new house.
