How to design the sewage pipe at the bottom? How to install sewage pipe correctly?

1. Generally, the drainage of toilets is called sewage, and the drainage of toilets, washing machines and kitchens is called wastewater, so both sewage and wastewater are called drainage.

2. The drainage of outdoor domestic sewage (waste water) pipeline is called sewage pipeline; The pipes that discharge rainwater are called rainwater pipes; These two kinds of drainage are collectively called: outdoor drainage pipeline engineering.

3. Sewage (wastewater) drainage pipeline system and rainwater drainage pipeline system cannot be discharged in mixed flow.

4. The calculation basis of outdoor sewage pipeline quantity is the construction drawing of outdoor sewage and rainwater drainage project. The calculation demarcation point of indoor and outdoor pipelines is the first sewage well where the indoor sewage pipeline extends outside.

So it can be replaced when it is installed outside, but it will be more troublesome when it is replaced, but it will take at least ten or eight years to replace it! However, if it is installed in a wall, it will be more difficult if you want to change it, not to mention it is more difficult than heaven, but it is impossible if you want to change it. However, there are also many villages that build their own houses or stay in outdoor self-dug sewage pits. If farmers use their own wells as drinking water, they will be close to sewage pits, which will lead to secondary pollution and threaten their drinking water health. If you must dig a sewage pit, it is recommended that people with wells stay away.

Its advantages are that it does not hinder the beauty of the facade of the external wall, and there is no disadvantage that the pipeline is easy to age when placed in the open air; Secondly, it is easy to maintain. If a part leaks, there is no need to work high above the ground like the external wall. If it can be sealed with bricks and then tiled, the effect will be better, and there will be no noise in the upper layer and the lower layer. After a long time, water pipes exposed to sunlight and rain will age. If the glue is kept in the wall for a long time, it will leak in rainy days, which will lead to water seepage in the wall. For example, in the corner of the house, the water pipe will be covered, beautiful and generous, and the water pipe will be durable.

Outdoor is better, although it is easy to be damaged, but it is also convenient to replace. In case the water pipe leaks, dirty things can't get into the room. The sound of pipe drainage at night will not affect indoor rest. Although the exterior wall will be a little ugly. Generally speaking, the outer wall is better.
