What is the proper method for connecting PVC pipes?

The proper method for connecting PVC pipes is to use PVC cement while ensuring the fittings are aligned correctly. PVC cement is a solvent that chemically bonds the surfaces of the PVC pipes and fittings, creating a strong, permanent connection. This process is critical because it requires the pipe ends and the fitting to be cleaned and primed before applying the cement. Proper alignment is essential to prevent issues like leaks or misaligned fixtures that could lead to plumbing problems down the line.

Using metal clamps and screws, heating the ends of the pipes, or duct tape does not create reliable connections for PVC. Metal clamps and screws may work for other types of materials but are not suitable for PVC, which relies on chemical bonding. Heating the ends of the pipes is a method applicable to different types of plastic but is unnecessary and potentially damaging for PVC connections. Duct tape, while it can provide a temporary solution, fails to create a robust, long-lasting seal that is expected in plumbing systems. Therefore, the use of PVC cement is the standard and best practice in connecting PVC pipes.
