The Mayfair by Bemis 26CHSL-000 toilet seat uses a slow-close mechanism designed to prevent the seat from slamming down. If your seat is closing faster than before, it may be due to wear and tear on the slow-close hinge mechanism. Unfortunately, these hinges typically do not have an adjustable feature to modify the speed at which the seat closes. Here are a few steps you can take to potentially improve the situation: Clean the Hinges: Sometimes, debris or dirt can affect the slow-close mechanism. Remove the seat and clean the hinges thoroughly with a mild soap and water solution, then dry them completely. Lubricate the Hinges: Apply a small amount of silicone lubricant to the hinge mechanism. Avoid using oil-based lubricants, as they can attract dust and debris. Check for Damage: Inspect the hinges and the slow-close mechanism for any visible signs of damage or wear. If any components are damaged, you may need to replace the hinge mechanism. Contact the Manufacturer: If the seat is only about a year old, it may still be under warranty. Contact Bemis customer support to see if they offer any solutions or can provide a replacement if the slow-close mechanism is defective. If none of these steps work, you might need to consider replacing the seat or the hinge mechanism if it is available as a separate part.
