If you live in a house built more than a few decades ago, then you have a cast-iron sewer. And the time will come when it will be a question of replacing cast-iron pipes with plastic ones.
It is desirable to replace the sewer riser at the same time in all apartments connected to it. For trouble-free operation of the sewerage, it is also necessary to replace the pipeline in the basement of the house and outside the building to the well.
Therefore, it is necessary to convince the neighbors of the need to complete this work in full, without waiting for an emergency. There are enough negative examples related to sewerage accidents in the house.
Yes, and collective replacement has several advantages:
• the ability to perform work in a short time. The operation of the riser will be stopped once, and not several times, if everyone replaces individually;
• the opportunity to do the work on their own, because among the residents there will always be people who have the skills to perform construction work and have the necessary tools;
• the opportunity to purchase the necessary materials in full with delivery, which will be cheaper for each family;
• dismantling of the cast-iron riser will be less labor-intensive, as there will be no need to cut the pipes.
It should be remembered that the replacement of the sewer riser should be made with a similar diameter of a plastic pipe (110), and a plastic pipe with a diameter of 50 mm will be required for the sewer wiring around the apartment.
Plastic pipes are connected with a socket. Tightness is ensured by means of a sealing gum inserted into the groove of the socket. Therefore, installation does not require special knowledge and skills in work. Pipelines are attached to the wall with special clamps. You can buy clamps for fasteners from the manufacturer here
When installing the pipeline, it is necessary to install inspection hatches in the places provided for by the project. Therefore, before proceeding with the disassembly of the pipeline, it is necessary to draw up a diagram with the application of the necessary elements (just apply all the elements of the existing riser to the diagram). If there is no hatch on the floor, if the pipeline is blocked, it will have to be cut to eliminate the emergency. This will result in additional costs.
Polyethylene riser has increased noise. To eliminate the undesirable effect, it is necessary to seal the places where the pipeline passes through the floor slabs with foam, close the well, in which the sewer and water risers are located, with moisture-resistant plasterboard.
By replacing old cast-iron pipes with polyethylene ones, you will save yourself and your neighbors from the danger of flooding with sewage, as well as from the unpleasant odors that arise when the cast-iron sewer is destroyed.
Simultaneously with the replacement of the cast-iron riser, it is desirable to replace the steel water riser with a polyethylene riser.When closing the riser well, it is necessary to provide for the possibility of access for servicing the water meter unit and sewer inspection hatches.
Replacing the risers with modern materials will ensure their reliable operation for many years and will allow for a quality repair of the bathroom.
