Proper functioning of the sewage system is undoubtedly essential in every house or apartment. It is important to know that sewage pipes play a key role. You have to choose their appropriate diameter. The installation and proper connection of glued pipes are also important.
PVC pipe diameters depending on the type of device
Let's start withsewage pipes . They usually have a diameter of 50 mm, 75 mm, 100 mm or 150 mm. An approach to a single device requires the use of a pipe with a diameter at least the same as the outlet. In places where sewage from several devices is collected, the pipes should have a diameter at least the same as the largest outlet. The situation is slightly different in the case of toilets. Here, there should be a separate sewage pipe connected to the riser. In turn, sewage risers have a diameter at least the same as the diameter of the largest approach. For example, in single-family houses, the drain pipe has a diameter of 150 mm, similarly to the sewer. The latter connects the internal and external sewage. The diameter of sewage pipes depends on the location. In toilets, pipes with a diameter of 100 mm are most often used, while in bathrooms they have a diameter of 40 to 50 mm.
Here the question arises: what is the reason for such a large variation? Well, sanitary facilities in the toilet use a larger amount of water and in a short time. There are also solid fractions, which means that if too small a diameter were used, the toilet would become clogged. Washbasins, bidets and urinals are connected with sewage pipes with a diameter that is on average half as small. It should also be remembered that pipes should also be selected for the number of storeys. In apartment blocks, pipes with a diameter of at least 100 mm are used. As you can see, the diameter of the pipes depends largely on the type of devices. For a bathtub and shower cabin, it should be 50 mm, while for connecting the sink drain - from 32 to 40 mm. The sewage pipes should have a slope of 2 to 15 cm per meter of length.

Glued water installation - tools and accessories
A properly carried out glued water installation requires the use of both appropriate pipes and tools or accessories. PVC pipes are perfect, which, as the name suggests, are made of a plastic such as polyvinyl chloride. They are very light. Additionally, they are resistant to corrosion, as well as resistance to several hundred chemical compounds. In addition, they meet the most restrictive sanitary standards for water transport. It is commonly believed that their durability is up to 50 years. They are also resistant to stress, but also dampen vibrations or noise.
For plumbing work, you need to prepare appropriate tools such as adjustable wrenches :
- Swedish type crimp wrenches ;
- frog pliers ;
- hook wrenches.
If you have to cut plastic pipes, use scissors equipped with a ratchet mechanism that prevents deformation of the cross-section.
Connecting glued pipes - what to remember?
Connecting glued PVC pipes is not that difficult, but it requires precision and commitment. It is essential to use the right PVC glue . You can choose a single-component one, but before the actual gluing, you should degrease and soften the surface. You can also use a two-component glue, and here there is no need to soften the surface. The pipes should be chamfered and dry-fitted. It is also necessary to mark the depth of the socket on the pipe. Only then can you start connecting the surfaces with glue. The joints should be perfectly matched. It is also necessary to rotate the pipe 90 degrees in the socket. Thanks to this, the PVC glue will be better distributed over the entire joint. The matched connection should be held for a few seconds for the glue to bind. Remember that the proper bonding of the glue usually occurs after 24 hours. Before starting to glue the installation, the dimensions should be carefully matched and the connection should be made dry.
