Bathroom sink pop-up waste UN model S2182 small mushroom without overflow (1 pc)

UN sink pop-up waste model S2182 is a small mushroom-style click-clack drain designed specifically for bathroom sinks without an overflow. Supplied as a single-piece unit, it provides a compact, minimalist drainage solution that opens and closes by pressing the cap. The product is suitable for installations where a simple, low-profile waste is required and where overflow protection is not present or needed.

Advantages

The mushroom-shaped click-clack mechanism offers straightforward press-to-open and press-to-close operation without additional moving parts or external levers. Its single-piece design simplifies installation and maintenance, reducing the number of seals and joints that can leak. The low-profile cap creates a clean aesthetic in modern or compact washbasins, while the absence of an overflow channel makes the waste compatible with sinks that have no overflow provision.

Suitable for

• Bathroom washbasins without an overflow
• Compact or minimalist sink designs
• Replacement of existing small pop-up wastes
• Installations where a simple, tool-accessible drain is preferred

Key specifications

• Type: small mushroom click-clack pop-up waste
• Design: single-piece construction
• Compatibility: for sinks without overflow
• Operation: press cap to open and close
• Finish: smooth, low-profile cap suitable for modern basins

How to use

To operate the waste, press down on the cap to close the drain and press again to release and open it. For installation, insert the unit into the sink drain hole and secure according to the sink and waste connection method used (typically with a sealing gasket and tightened nut beneath the basin). Ensure the mating surfaces are clean and use an appropriate sealant or gasket if required by the sink design. Periodically remove and clean the cap and drain aperture to prevent buildup of debris and maintain smooth operation.

Usage recommendations

Verify sink compatibility before purchase: measure the drain hole diameter and confirm that the basin has no overflow. During installation, hand-tighten the securing nut and then apply only minimal additional torque to avoid damaging the sink or waste. Clean with non-abrasive materials and mild detergents to preserve the finish and mechanism.
