Each of us eats his weight of waste in about one minute. Our family number can double every 30 minutes. We feed, multiply and eat all through waste matter until it is eaten up. We change the waste into water, carbon and other elements which run harmlessly out of your waste system. These elements are then available food for plant life.
Cables can only poke a hole through the mess which leaves a base for new waste to adhere to.
If you do not put my family to work, you will keep fighting the problem instead of solving it. Hot, dangerous drain openers become more diluted and weaker the farther down a pipe they go. The result can be very costly. We eat our way up, down and across any pipe or system. My family of friendly Bacteria can, and do, digest vegetation and animal waste.
