Generally, blockages of pipes occur due to deposits of soap scum, fats, oils, hairs, food particles, etc., which slowly creates fungus formation & also gives bad odours after decomposition of all debris. The result of this are blockages of pipes. To clear this block/clog, we need to put a Drain Cleaner in the application area, which when mixed with the water, releases heat & melt all blocked particles. And water can easily flow through the pipes making it clean & clear.
