Ensure a plumbing system runs efficiently and effectively with these wastes and traps. There is a variety of waste pipework available that helps direct waste water from areas, such as basins, baths and showers, into the drainage network. Some are shaped with a bend in the pipe path to retain some water after a fixture has been used in order to create an air-tight seal that prevents sewer gas from passing from the drain pipes back into the premises. It can also capture oversized objects such as coins or jewellery that have mistakenly slipped down the plug hole, and can be taken apart to allow these items to be rescued. Wastes and traps come in a large choice of designs, shapes and sizes to get the best fit for any layout.
