materials tend to expand when they get hot, and that is true for sewer pipe material as well. Whether it's cast iron or ABS, the pipes will try to expand when they get hot and when they try to get longer they'll slide across wood or other materials. The "knocking" noise is the pipe fitting tightly against the wood and when the pipe has expanded enough it moves suddently and for a short distance, producing a "pop" type of sound. If you can expose the pipe you can cut out the wood where it is tight and possibly put in other material so that the pipe doesn't rub so hard.

Clogged drains are caused by the accumulation of sticky material in the water pipes. Many times stuff like hair, food, plastic pouches.. gets stuck in the pipes and starts accumulating. Because of this the water from the kitchen or shower sink takes time to drain. Many times the drain pipes emit foul odor. Once the pipes are blocked, either the water stops draining from the sink or the debris starts coming out of the sink and toilets.
