Troubleshooting
Difficulty inserting liner into pipe
Ensure the pipe end is clean and has not been deformed. If the pipe is slightly oval, gently reshape the end before insertion. Do not force the liner.
Leak at the fitting connection
Recheck that the liner was fully inserted into the pipe. Ensure the MDPE pipe conforms to the compatible standards. Verify the Philmac fitting is correctly installed and tightened according to its specific instructions.
Pipe collapses inside fitting
This indicates the liner may not have been used or was not fully seated. Ensure the liner is correctly installed to support the pipe wall during fitting compression.
