Most rural houses of the old buildings do not have a bathroom. This was due to preexisting building regulations. Over time, improving living standards led to their revision, and now equipping housing with a bathroom is considered the norm. There are organizations that quickly install a storage septic tank, connect a toilet to it and draw up a maintenance contract.
When building a new house, this can be a big help, but how to install a toilet without heavy equipment coming into the garden? Can I make a toilet in my house with my own hands? What engineering schemes are used for private homes? What physical laws will need to be taken into account?
How to choose a place to connect to the sewer
When they make a toilet in a private house with their own hands, sometimes they forget about the law of communicating vessels. When planning the withdrawal of waste, one should also consider the impossibility of getting it back through the sewer system. During heavy rains, heavy snowmelt, or sewage blockage, sewage flows over the edge of the well. If there is sewage down the street and one of its wells is located next to the house, you can connect the exit from the private house to it only when the house is located higher.
In small towns, local rivulets are used to drain domestic sewage. Typically, sewer wells are built taking into account the natural slope of the soil surface. When the well overflows, the effluents come to the surface and flow down the slope. Private houses, standing on such a street, residents connect to the city sewer independently.
Having decided to connect the home system to the city, from the two wells choose the one that is located lower on the slope. Then in case of clogging, the water will not go through the toilet into the house.
Septic tank: do overflow compartment
Low-rise construction is developed in Finland. The climate in this country is similar to the Russian one, and you can use the experience of installing septic tanks of Finnish builders. First of all, it is customary to install industrial septic tanks for wastewater, which have three or four compartments. Waste enters the first, rises and through the overflow hole fills the second, then reaches the top of the tank and so fills all four compartments. Solids remain in the first tank. As the remaining containers fill, the water in them settles and in the last compartment is already almost transparent.
When it is decided to make a toilet in your home with your own hands, the accumulating septic tank is often made from improvised means. Two hundred-liter barrels that dig into the depth of freezing of the soil proved to be quite good. It will take six or eight barrels. Four knock out the bottom and cut out an overflow hole with a diameter of 110 mm.
Four barrels are placed in the dug hole next to them, after which they are poured to the level of the upper sides, not forgetting to compact the soil around them. Hollow cylinders are installed on each buried barrel, which were obtained after removing the bottoms of the remaining four barrels. Bury these upper containers carefully so that there is no displacement. After the soil has closed the barrels to the drain holes, tees of a plastic pipe with a diameter of 110 mm are inserted into them in such a way as to connect the entire system. Four compartments are obtained, in the last of which technical water for irrigation is formed.
If you limit yourself to only one container, it will quickly fill up and begin to spill over the edge, spreading the smell. For watering, such contents of the compartment will not work, you will often have to call the sewage system. Those who made a single chamber septic tank often regret it.
What is air
When arranging a toilet in your home with your own hands, you should not forget about the fan riser, popularly referred to as air. When the toilet is connected to the sewerage, it is envisaged to mount on this section of the pipeline overlooking the roof. It is convenient to place it against the wall behind the toilet. On the roof, the riser outlet is closed with a cap to prevent foreign objects from entering it.
What is it for? When you press the trigger valve, the contents of the toilet enters the sewer pipe. It causes rarefied pressure. If it is not normalized by drawing in air through the fan riser (if there is none), then this happens through plumbing fixtures.
It happens that a self-made master made a toilet in a country house with his own hands and for the first time flushes water in the toilet, and she leaves very slowly. As if the pipe were clogged. But it’s worth mounting an air duct, water is already swirling through the sewer pipe.
Someone does not understand why to bring the riser to the roof. For the functioning of the drain, you can leave open the audit in the sewer in the basement. But the smell from it will fill the whole house. For the same reason, do not bring the riser to the attic.
Bad smell in the toilet
If, after installing the toilet in your own home, the smell of sewage appears in the room, some try to solve the problem by installing forced ventilation. But this does little to freshen the air. A properly installed system must not emit any odors. This means that there are engineering miscalculations at the construction or design stage.
In a septic tank, which consists of one tank, which does not have the ability to overflow, high gas pressure is created due to biodegradation processes. They break through the toilet water shutter and enter the room. If a funnel is installed between the toilet and the septic tank , the gases exit into it.
Conclusion
Sewerage is a complex system in which physical laws operate. Failure to understand this leads to serious problems. Therefore, it is worth spending time and figuring out how to make a toilet in a wooden house with your own hands.
