Practical Notes
Verify the rubber profile of the plug against the waste coupling, as hardened or undersized rubber will cause slow leaks.
Ensure metallic components like the chain and stay ring are properly chromium-plated or made of stainless steel to avoid rusting in wet environments.
Plastic plugs must be manufactured from materials capable of withstanding hot water discharges without deforming.
