Your application should be thorough but not excessive. A good tip is to apply a layer of cement to both the pipe and the fitting for maximum adherence.
Joining the Sections: Quickly but carefully push the pipe into the fitting, giving it a slight twist to spread the cement evenly. Hold the connection for about 30 seconds to allow the adhesive to set slightly before moving on.
Setting the Pipes: While you join each section, ensure that the pipes are level and that all fittings are aligned properly. Misalignment can lead to problems like blockages or leaks.
Securing Cast Iron Pipes
Using a Hub Connection: If you are working with cast iron, you may need a hub connection. This involves sliding the bell end of one pipe over the spigot end of another. After dry fitting, apply a liberal amount of lead and oakum to seal the edges properly.
Lead and Oakum Technique: After applying the lead and oakum, you will generally need to pour molten lead into the joint to create a secure seal. This method is traditional but requires some experience.
Testing Your Connections
After completing your connections, it’s time to test your work. This step is crucial to ensure everything is correctly sealed.
Visual Inspection
Start with a thorough visual inspection of all joints and connections. Look for any gaps, uneven alignments, or signs of excess adhesive that may impact the integrity of the connection.
Conducting a Water Test
After the visual inspection, it’s wise to conduct a water test:
- Fill the System: Temporarily seal off the sewer system and fill it with water, such as by using a hose or filling a bathtub.
- Monitor for Leaks: Observe connections for any signs of water leakage. If you notice any leaks, you may need to disassemble the affected area and reapply cement or adjust the fittings.
Final Touches and Cleanup
Once testing is complete and you are confident that the connections are leak-free, it’s time for some finishing touches.
Backfilling Trenches
If you excavated any trenches for installation, backfill those areas with soil. Be sure to compact the soil properly to avoid future settling, which could impact the integrity of your sewer connections.
