Pipes for the bathhouse sewerage system are no different from sewer pipes in a private house. However, in the case of installing monolithic floors with outlet pipes embedded in them, it is better to opt for cast iron pipes, which are durable and have very high mechanical strength. With proper caulking of the sockets, cast iron pipes will last for decades.
Polymer pipes laid hidden with embedding in the floor can deform under the influence of high temperatures of wastewater or, over time, the sealing rubber rings in the socket joints can dry out, which will lead to leaks, wetting and gradual destruction of the floor structure.
Internal piping in a bathroom in an apartment, in a private house or in a bathhouse is carried out in such a way that the location of sinks, washbasins, toilets, bathtubs and other devices is as compact as possible, and the length of horizontal sections of the sewer is minimal.
All plumbing fixtures are connected to the sewer through a water seal (water lock) - a curved part of the pipe in which, after draining the water, a certain amount of liquid remains, preventing the macedonia mobile database of stench from the sewer into the interior. In another way, a water seal is sometimes called a siphon.
Wastewater is sent through discharge pipes to the collecting collector and subsequently to the sewer riser.
The sewer riser is a vertical pipeline in which wastewater is collected from different floors and transported down to the outlet into the external network.
The riser cannot have a diameter smaller than the diameter of the outlet pipes of the sanitary devices connected to it.
The exhaust part of the ventilated riser is brought out above the roof to a height of at least 30 cm from an unexploited flat roof or 50 cm from an unexploited pitched roof.
The riser exhaust must be located at a distance of at least 4 meters from openable windows, balconies or vents.
The exhaust part of the riser serves to ventilate gases accumulating in the sewerage system, and also facilitates the free passage of wastewater in pipes without breaking the water seals connected to the sewage disposal system of sanitary devices.
If the pipe is not connected to the atmosphere, the vacuum created when liquid moves through it will lead to the "sucking" of liquid from the water seals (the so-called "breakdown of water seals"). After this, all harmful gases from the sewerage system through broken water seals in which there is no water begin to freely flow into the interior.
