If you find it difficult to loosen or tighten your drain plug, there is a chance that it may be stripped. Here are some telltale signs:
• You hear squeaking when the plug is turning
• You see grooves on the surface of the plug where a tool has been used to attempt loosening/tightening
• There is resistance when you try to turn the plug, but no movement occurs. If any of these signs appear, contact a professional plumber for help with replacing your drain plug.
