The McAlpine STW4-95 50mm Water Seal Shower Trap with Universal Outlet is a plumbing component used to connect the waste pipe from a shower to the drainage system. The STW4-95 trap is designed to be installed below the shower tray and is commonly used in residential and commercial plumbing installations. The STW4-95 shower trap features a 50mm water seal, which helps to prevent foul odours and gases from escaping from the drainage system and entering the living space. The water seal also helps to prevent blockages by trapping debris and preventing it from entering the drainage system. The universal outlet allows for easy connection to a range of waste pipe sizes and types, making it a versatile choice for a variety of plumbing applications. The trap also features a removable grid, which allows for easy cleaning and maintenance. The STW4-95 trap is different from the STW4-R trap in that it has a shallower water seal, which can be beneficial in certain plumbing installations where a deeper seal is not required. However, a shallower seal can also increase the risk of blockages, particularly in situations where there is a higher volume of water being used. Overall, the McAlpine STW4-95 50mm Water Seal Shower Trap with Universal Outlet is a reliable and easy-to-use plumbing component that is suitable for use in a range of different plumbing installations. It is particularly useful in situations where a shallower water seal is sufficient and a universal outlet is required for easy connection to a range of waste pipe sizes and types.
