The McAlpine USG3WH is an untrapped gully designed for use in wet room areas and showers. It has a 1½" horizontal outlet and comes with a clamp ring and cover plate for secure installation. The untrapped design means that it does not have a water trap, which allows odors and gases from the drainage system to enter the room. Therefore, proper ventilation is necessary to prevent unpleasant odors and gases from entering the room. The clamp ring and cover plate are designed to provide a secure and stable installation, while also allowing for easy access to the waste trap below. The cover plate is made of high-quality materials that are resistant to corrosion and chemical damage, ensuring durability and longevity. The 1½" horizontal outlet is suitable for standard 1½" pipework, making the McAlpine USG3WH compatible with a variety of drainage systems. The horizontal outlet allows for easy installation and connection to existing pipework. Overall, the McAlpine USG3WH is a reliable and efficient plumbing fixture that is designed to provide effective drainage for wet room areas and showers. However, it is important to note that the untrapped design of the gully means that odors and gases from the drainage system can enter the room, so proper ventilation is necessary to prevent unpleasant odors and gases from entering the room. ・ Available with White Plastic, Polished Stainless Steel or Chrome Plated Brass Cover Plates ・ 1½" BS EN 1329-1:2000 Solvent Weld Horizontal Outlet ・ Supplied with 2" x 1½" socket reducer ・ Sheet floor gully suitable for concrete and suspended timber floors ・ Manufactured in ABS to the highest quality
