Sealing PVC pipe so that it will not leak is a very straightforward and simple process. But, it is important to remember that PVC cement sets within seconds, so it is imperative that you connect your two lengths of pipe immediately after the PVC glue has been applied. PVC is an ideal material to plumb with because, like galvanized or steel piping, it will not rust over time.

Sealing PVC

  1. Clean both ends of the pipes that you wish to connect with a dry rag. This will help remove any loose debris left over from when the pipes were cut.

  2. Apply a thin layer of PVC primer/cleaner to the areas of both pipes that you want two join together. Primer simply helps clean the areas further and creates a better, longer-lasting seal. There will be an applicator inside of the bottle that you can use to apply the primer/cleaner.

  3. Apply PVC cement to the areas that were just coated with PVC primer/cleaner. There will be an applicator inside of the bottle that you can use to apply the primer/cleaner.

  4. Connect the two section of pipe together and hold them in place for 10 seconds.

  5. Tip

    Do a dry run of your pipe installation before applying any glue. It's easier to make adjustments this way.

    Warning

    Wear gloves when working with PVC cement.
