How to Apply a PVC Cap to a Pipe
A polyvinyl chloride (PVC) cap is a mixture of plastic and vinyl material. The pipes are durable, do not get damaged easily and can be used for a long time. The PVC material does not get damaged so easily. Hence, PVC is commonly used in water piping systems, underground wiring and drain lines. To prevent the PVC pipes from leaks, you must cover the top of the PVC pipe with PVC cap. The cap is generally available for pipes of 2 inches in diameter or more.
Step 1: Applying Primer
Wipe the ends of the pipe thoroughly. The interior surface of the PVC cap socket and the exterior surface of the PVC pipe has to be applied with PVC primer.
Step 2: Applying Cement
To both the primed surface, apply PVC cement. While turning the fitting 90 degrees, slide the socket of the cap fitting to the end of the pipe. This spreads the PVC cement evenly in the joint. Now set the fitting in place for a few minutes to allow the PVC cement to settle.
Step 3: Sealing
Using the adjustable wrench, tighten the PVC cap by turning the PVC cap in the clockwise direction. This seals the cap to the PVC pipe.
Step 4: Testing
Test the capping by turning on the water. If the cap is applied to a water supply line, make sure that the installed PVC cap does not leak. If the water leaks, use the wrench to tighten the PVC cap by about quarter to half of its turn to prevent the leak.
