- Cutting tool for pipes (if needed)
- Pipe deburring tool (optional, for smoothing edges)
Now, prepare your pipes:
- Cut the pipe to the required length if it’s not pre-cut.
- Ensure the pipe ends are clean and smooth. If there are any rough edges or burrs, use a deburring tool to smooth them out. This ensures a tight, leak-proof seal when you insert the pipe into the fitting.
Step 2: Insert the Pipe into the Fitting
Now it’s time to connect the pipe to the push-fit fitting. Here’s how:
- Align the pipe with the fitting and insert it into the opening of the fitting.
- Push the pipe firmly into the fitting until you feel resistance. For most push-fit fittings, you will hear or feel a click, indicating that the pipe is securely locked in place.
It’s important to ensure the pipe is fully inserted to avoid leaks.
Step 3: Check for Proper Installation
After inserting the pipe into the fitting, you need to verify that the connection is correct:
- Check the fitting’s indicator (if applicable) to confirm that the pipe is properly inserted.
- Give the pipe a gentle tug to make sure it’s securely locked into place. The pipe should not move or come out easily.
- If possible, inspect the fitting for any visible gaps or misalignments to ensure the seal is tight.
Step 4: Test the Connection
Before finalizing the installation, it’s essential to test the connection:
- Turn on the water supply and run water through the connected pipes and fittings.
- Check for leaks around the fitting. If you notice any water dripping or dampness around the joint, turn off the water and recheck the fitting. It may require reinserting the pipe properly or adjusting the fitting.
Step 5: Final Adjustments and Securing
Once you’ve confirmed there are no leaks:
- Secure the fitting by tightening any locking mechanisms (if applicable) or by ensuring it’s firmly positioned.
- If necessary, you can use pipe supports or clips to secure the pipes in place, preventing movement and reducing the risk of stress on the fittings.
Now, your push-fit fittings are properly installed, ensuring a smooth, leak-free water filtration system!
Common Mistakes to Avoid When Using Push Fit Fittings
While push-fit plumbing fittings are easy to use, there are a few common mistakes that can lead to issues like leaks or improper connections. Avoiding these mistakes will ensure your water filtration system works efficiently.
