Alca APV0020 Dry Valve for Alca Drain

Forget unpleasant sewage odors in the bathroom! Alca APV0020 is a special "dry" valve (siphon) designed to replace the standard water trap in Alca point drains (e.g., APV140, APV31 series). Unlike a standard siphon, this mechanism does not require a constant presence of water in the system to block odors. The valve flap opens only when water enters, and closes tightly as soon as the water flow stops. This accessory is an ideal and essential solution: During floor heating: Heating quickly dries out water in a conventional drain, but the dry valve completely eliminates this problem. In rarely used spaces: In spare bathrooms, summer cottages, or hotel rooms, where water in the drain can evaporate and dry out over a long period. Features: Compatibility: Fits Alca point drains (APV140, APV31, and other models). Easy Installation: Does not require a craftsman or floor demolition. After removing the drain's top grate, simply remove the old (water) siphon and install the APV0020 dry valve in its place. Material: High-quality plastic, resistant to temperature and chemicals.
