Installing PVC Pipe Test Caps Without Knockouts
Tools Needed
- PVC primer and cement
- Pipe cutter or saw
- Measuring tape
- Deburring tool
Step-by-Step Installation Process
- Measure and Cut the Pipe: Use the measuring tape to determine the length of pipe you need, then cut it to size.
- Deburr the Edges: Smooth out any rough edges from the cut to ensure a good seal.
- Apply Primer: Use PVC primer on both the pipe end and the inside of the test cap.
- Cement the Cap: Apply PVC cement to the same areas and quickly press the cap onto the pipe end, giving it a slight twist to ensure a secure fit.
- Allow to Cure: Let the cement cure as per the manufacturer’s instructions before conducting any tests.
