Key Takeaways
- Schedule 80 PVC can be glued to Schedule 40 PVC if their outside diameters match.
- Both schedules share the same outside diameter for equivalent nominal sizes.
- Always clean and bevel the pipe ends prior to applying adhesive for a stronger bond.
- Use appropriate PVC primer and adhesive for optimal bonding and leak prevention.
- Many users report successful connections under pressures up to 100 psi when proper techniques are followed.
Compatibility Overview
When it comes to plumbing projects, understanding the compatibility between Schedule 80 PVC and Schedule 40 PVC is crucial. You can actually glue them together as long as their internal and external diameters match for the same nominal sizes. This compatibility is a big win for your plumbing needs.
While Schedule 80 PVC has a thicker wall than Schedule 40, they both share the same outside diameter for the same size. This design makes it easier to create proper connections between the two.
Before you get into the gluing process, it's smart to dry fit the components to ensure everything aligns properly.
Using the right primer and adhesive specifically designed for PVC is key. This enhances the bond and helps prevent leaks when you connect Schedule 80 to Schedule 40.
Plus, transition joints between these two schedules have been tested to withstand up to 100 psi without leaks, showing they're reliable for your plumbing applications.
Gluing Procedure
Now that you know Schedule 80 and Schedule 40 PVC can be glued together, let's get into the gluing procedure.
First off, grab some sand cloth or sandpaper and clean the ends of both pipes. This step is crucial to remove any debris and contaminants that could mess with the adhesion.
Next, apply a bevel to the ends of each pipe. This will help create a stronger bond.
Once that's done, use a PVC primer on both the pipe and the fitting. This primer is essential for a solid chemical bond and helps eliminate any leftover surface contaminants.
After priming, it's time for the adhesive. Make sure you cover both surfaces well; more coverage means better adhesion and fewer chances of leaks later on.
When you've applied the glue, hold the joint together for a few seconds to let it set. Don't rush this part!
Finally, be sure to check the adhesive manufacturer's instructions for curing time before putting any pressure on your new PVC conduit joint.
Follow these steps, and you'll have a reliable connection.
