Store bought drain cleaning solutions are not the cure-all concoction that they advertise themselves to be. In fact, these harmful chemicals may do more damage to the drain then good. Using store bought chemicals to clear a drain is a temporary fix that will ultimately be hazardous to the health and longevity of your residential plumbing system. Store bought chemical solutions can cause permanent damage to your drains, lead to additional clogs in the future, and eventually result to more costly plumbing repairs.
