How to make a sewer in the bath: step by step instructions
The bath, as well as all other premises needs well thought over sewer system. The presence of sewage is very important, because in the bath is always wet, there is a shower, steam room, and sometimes a pool. As a rule, the floor is made quite dense without possible cracks. It also has a certain inclination in the direction of the ladder to drain water into the drainage well. It should be noted that the implementation of work on the manufacture of sewage in the bath is quite understandable. If you make an effort, then this work can be done independently.
Drainage system
In the event that a small bathhouse is planned, which can be received by several people, then it is enough to choose one of the simple methods for draining water - drainage sewage. All work can be done in five stages.
Stage number 1. Based on the level of freezing of land in your area, near the bath arrange a drainage well. If the level of freezing of the ground is 50 cm, then the depth of the pit should be at least 120 cm.
Stage number 2. Bottom lay clay in 100 mm thickness. Also clay to overlay the foundation of the bath. Leveling clay in a trench, it is necessary to give it the shape of a gutter. Already at this stage you create a uniform bias towards the well.
Stage number 3. Claydite, a mixture of sand or crushed stone is evenly poured on top of the clay. This will serve as drainage.
Stage 4. Drainage is filled with earth, and then tightly rammed.
Stage number 5. The drain pipe that departs from the bath must be securely warmed. This will prevent freezing.
Tip! From time to time the sewage system needs to be cleaned, because the drainage can be blocked by suspended particles.
If there is sandy soil in your area, then it is recommended to build a horizontal drainage pad. For this purpose, a trench is pulled out, the depth and length of which is one meter, and the width is thirty centimeters. In this case, the bottom is filled with 20 cm of rubble, and then closed with soil. Then all the wastewater goes to this place.
Pit making
If in the selected area the soil does not pass water well enough, then it will be rational to equip a drainage system with a pit around the house. It is designed to collect wastewater after which it is removed. As a rule, it must be made of waterproof material. This is important, since water will accumulate in the pit, and then go along the pipe beyond the boundaries of the site. To work the pit was the most effective, you must make a water seal. It will limit the penetration of fetid odors into the bath. So, for this you need to do the following:
- The entrance to the pit where the drains from the sewer pipe are to be made should be at a height of no more than twelve centimeters from its bottom.
- A plate is installed under the pipe, which should be fixed only from above.
- At a distance of six centimeters leave the distance from the bottom of the pit to the plate. For the formation of a water seal, this distance will be quite enough.
To transport the liquid from the bath, you can use PVC pipes. If necessary, and also, if possible, disposal of waste to the general sewage system, you can connect the bathroom.
Sewage disposal and sewerage laying
To make a sewage system should be based on the number of visitors to the bath. If there are many visitors, then one drainage system will not be enough. To do this, just need to make a sewage system. So, the sequence of works:
- At a distance of half a meter from the foundation, a hole is dug inside. Its depth can be 1.5 meters.
- A trench is being laid from the pit in order to discharge it in the future.
- At a distance of three meters is made drainage well, the volume of which can be 2.5 square meters. m
- It is recommended that the trench be shaped boat.
- After this, the well and the trench are well treated with clay.
- From the side of the bath to make a sufficient bias towards the drainage well.
Tip! If possible, the sewage is best connected to a centralized sewer system. This will prevent the violation of sanitary norms.
What to do
As practice shows, it is not recommended to use metal pipes or wooden boxes. In a short period of time under the influence of corrosion they will rot. That is why it is best to use plastic or cast iron pipes. If you plan to install a bathroom, the pipe should be O 100 mm. If only water is drained from the bath, without a bathroom, then an O 50 mm pipe will suffice.
Additionally, the sewer system can be equipped with a ladder. His goal will be to create a water gate. It is best to install a stainless steel ladder. The ladder must be fixed so that the plate is at an angle of five centimeters from the bottom.
Bath floor and manhole
An important component is the arrangement of the floor. Based on the sewage system used, as well as the size of the bath, the floor can be of two types:
- Capital. In this case, the floor is tilted exclusively in one direction. Under the base of this floor is a receiving tray, from which water is sent to the pit.
- Leaking This type of floor is fixed directly to the logs. Between the boards is a gap of 50 mm.
Now consider how to make a manhole. When do we need a manhole? It is required in cases where the scheme of the entire sewer system is large enough. It is necessary to clean and inspect the system if necessary. A manhole is a concrete pit with brick walls. To protect the flowing water from freezing, it is recommended to protect such a well with two covers, especially in winter.
The outer cover can be covered with earth, this will allow not to draw attention to it on your site. The inner lid needs additional thermal insulation.
After the work is completed, the drainage system inside the bath, well, and the trench must be filled with sand and gravel. The top layer will be the ground, which after backfilling is recommended to tamp. In order to prevent from time to time, you can clean the sewer system. This will prevent pipe clogging. If you have a drainage system, the more it will need to be cleaned. Otherwise, the water will very badly seep into the ground.
Be sure that all the efforts you have spent on the construction of the bath, including the sewage system, will be justified when you receive guests there or are soared alone. Choose for yourself the best option that you can master. If in the process of work you have difficulties, ask us your questions.
