Compression fittings create a secure, watertight seal by compressing a collar onto the pipe, which is achieved without the need for soldering, glue, or crimping, making installation faster and easier.

After hand-tightening, use a wrench to tighten an additional 1/2 to 3/4 turn. The seal should feel firm and secure without deforming the pipe or fitting excessively.

Ensure the pipe is fully inserted into the fitting and the compression collar is tightened sufficiently. Check that the pipe end is cut square and free from damage. Inspect the pipe for any imperfections where the seal is made.

Verify that you are using the correct 20mm MDPE pipe. Ensure the pipe end is clean and not deformed. Slightly warming the pipe end in warm water may help, but do not use excessive force or heat.

Check for cross-threading or damage to the collar or fitting threads. Ensure the correct size fitting is being used for the 20mm pipe.
