Light and easy to work with, the PVC pipes are one of the most used for most sewer lines in homes materials. Even if the indicated accessories are used, they can be connected without difficulty to pre-existing galvanized or cast iron pipes.
Materials needed for a basic drainage installation or replacement project include PVC pipes and fittings (elbows, couples, crosses, nets, lids, etc.), primer and cement. Tools indicated with a saw for PVC, a miter box, a blade, and tape measure.
The PVC pipes are easy to assemble, but care should be taken do well. Gaskets should be primed and glued incorrectly or may leak. If an accessory to be screwed in is to be installed, the alignment marks must be respected to ensure connection to the indicated side and to avoid seepage.
It should be noted that, once the glue is dry, mistakes in pasting the joints in the wrong direction can be difficult to correct, even leading to the need to cut the defective section and start over. Before tackling the final job, it is convenient to practice cutting and joining the pieces until you are sure that no mistakes will occur.
First, you should cut the PVC pipe according to measurements taken with the tape, using for this purpose a PVC saw or, failing that, any saw with fine teeth. In this step a miter box can be of great help to hold the pipe in order to make the perpendicular cuts.
Then, using the blade, the inside and outside of the sawed edge of the pipe is scraped, in order to remove any burrs that might have been left after the saw.
The pieces are assembled as a test, without primer or glue, to ensure that everything fits correctly. Then the parts are dismantled remembering the order in which they will be submitted again to the definitive assembly.
A large primer line is applied to the ends of the tubes to be joined and to the interiors of the fittings. Once it has dried it proceeds to apply the adhesive cement outside the PVC pipe and inside the coupling.
Immediately afterwards the tube must be inserted into the fitting and given a small twist and the union is maintained for about 20 seconds (although this will depend on the manufacturer’s instructions). Some cements tend to rebalance a little around the joint, so it is recommended to have a damp cloth on hand to remove the surplus before it dries.
To finish the job, wait at least 30 minutes before draining the water run through the new PVC pipes.
Installation of PVC Pipes: Important Recommendations
While buying the materials for the proposed installation of PVC pipes is important to ensure that both the primer and the adhesive cement are appropriate for this type of plastic, since the use of the wrong product can end up ruining the entire installation.
The support and glue for PVC pipes are flammable and produce unpleasant and harmful emissions, so it is recommended that both sparks and flame protected products, and open a window when working to provide good ventilation. Once it is finished, the lids should be tightened firmly.
