Since the work of the riser affects the quality of life of not one family, but the whole part of a multi-storey building. Any redevelopment associated with the use of home property, including apartment risers, must be coordinated with the managing organizations. Only having received the appropriate permission in writing, he can invite the installers of the management organization or a private company to carry out the work.
It is much easier with this question for people who live in country houses.
What pipes to choose for hot, cold water and for sewage
In old high-rise buildings, apartment risers are most often made of cast iron or galvanized pipes. These are metal products that naturally corrode, and therefore, sooner or later, require replacement. Typically, the service life of metal structures is 25 years, but in practice, apartment owners do not change them much longer. It is interesting that risers with hot water undergo a destructive process faster than with cold water, therefore, an emergency situation with them may occur a little earlier.
The fastest pipe wear occurs in the places of interfloor ceilings, therefore it is important that the joining of the old part of the riser with the new one is carried out outside the ceiling, for example, at the neighbors below and above.
Experts recommend replacing old cast-iron risers in apartment buildings with polypropylene ones. At the same time, ordinary pipes made of polymer and metal-plastic are suitable for risers with cold water, but for hot water supply polypropylene pipes are needed for heating. These pipes have a number of features:
Unlike cast-iron pipes, whose service life is a quarter of a century, polypropylene risers will serve you faithfully for at least 50 years, and pipes for supplying cold water, in general, can celebrate their centenary in your apartment.

For internal sewerage, pipes made of propylene and ethylene copolymer (PPR) are suitable, they can withstand temperatures up to + 70C. Pipes of the PPs type behave even better, which calmly withstand temperatures up to + 95C and short-term exposure to even higher temperatures.

All work on dismantling and installation of risers must be carried out by qualified specialists. As for which pipes are best to use?
When laying sewer pipes in an apartment, the following types of pipes are used:
Before proceeding with the purchase and installation of sewer pipes, it is best to draw up a project where you indicate all the drain points and the type of plumbing equipment. This will help you navigate what diameter and how long the pipe is needed.

If we are talking about replacing the entire water supply and sewerage riser in a multi-storey building, all work must be started with obtaining all permits. Such work must be coordinated with all residents of the house.
If we are talking about work within the same apartment, then it is easier and you can do everything in a few hours. But in this case, you also need to warn the neighbors in the riser.
The main thing is to choose pipes of the correct diameter and size.
