Most likely cause & what to check
1
Turn off the water supply. Gently tighten the compression nut by a quarter-turn only.
2
Do NOT over-tighten — this can crush the olive inside and make the leak worse.
3
If tightening doesn't stop it, dismantle the fitting, inspect the olive, and replace if damaged.
4
Wrap PTFE tape on threads before reassembling.
