How to connect riser sewer pipes( preparation)
Qualitative measurements and thorough preparation will become the engine of the main work. For pipes it is necessary to take care of the diameter, which should be 5 cm for plumbing fixtures and water lines. If the communication is located from the toilet, the diameter should be increased to 11 cm. For installation, cast iron pipes and plastic corners are still required.
At the beginning of the work, the first thing to do is replace the riser and connect the product from the plastic and from the cast iron.
Elimination of old cast iron communications
Dismantling of cast iron products is a cautious and careful process. You can use a rubber hammer, which, applying precise shocks on cast iron, leading the joints of the product into a non-working condition. The old communication is twisted in all sorts of ways to remove the pipe from the socket.
If the socket is damaged, then it is necessary to use the bulgarian and cut off the site before it. In such a case the connection quality is provided. In addition to the Bulgarian, you can use a hacksaw for metal, but this is except labor-intensive and long. A new crop is cleaned of the remnants of the old pruning. Break off cast-iron communications is impossible for the reason that cutting though in another place will still be necessary.
How to connect the riser pipes from cast iron and plastic:
connection principle The main task for the connection is to avoid all kinds of temperature influence and mechanical interference. Leakage occurs due to leakage. The temperature "tolerance" of plastic and cast iron is different, therefore, for precaution, it is important to simply connect them correctly. The brewing of plastic blanks placed in a cast iron socket( in a cement mix) will not be enough, because, plastic will deform and cement will crack. The tightness is broken.
Advice: to seal the plastic and cast iron, porous rubber can be used, having wrapped the plastic pipe with it, and the remains, drowning in the socket.
If there is a bell, then docking is possible even by the most unprepared person, if not, then there is the possibility to use fittings. Namely, press fittings for metal-plastic joints, which have threaded on both sides for cast iron and plastic.
How to connect the riser pipes with the
cast iron bell Before starting work, prepare the rubber adapters with a diameter of 5 cm or 11 depending on the size of the workpieces.
Docking occurs:
- Rust removal from old layers of paint and dirt.
- Application of sealant to the rubber adapter.
- Drown the adapter into the cast iron bell to the end.
- Place the adapter at the end of the plastic pipe.
The product is ready for use, reinstalling, cleaning, checking.
Important! The plastic connection in the cast-iron socket is located with a slope towards the riser.
Mounting with socket
For this installation, smooth cuts of pipe edges are required, and the installation process takes place in two stages:
- The surface is cleaned and a sealed rubber adapter is placed on it. Then put on the plastic adapter.
- In this case, the plastic pipe is included in the plastic adapter and the product is ready for use.
The whole construction is dismantled, the main thing is that the diameters coincide.
If the connection is not sufficiently tight, then you can apply a silicone sealant, which pour all the leaky holes.
The video shows how you can still connect the
communications The proposed connection options can be tried for gas pipes and PVC.For the work you will need a pipe cutter, which will be applied to the thread on cast iron. The socket is not with it, however, as well as the carving. Therefore, it is cut, pre-lubricated with a special lubricant.
The completed thread is wrapped in a pack and the press fitting is wound on it and screwed without a key. The spanner can spoil everything, damaging the fitting and the pipe with a touch.
As it turned out, the procedure for replacing pipeline communications and their docking is not a difficult task, but it requires your accuracy and compliance with instructions.
