Review on Roebic Destroyer Exclusive Biodegradable Eliminates by Jamie Jenkins

Helps with regular use. But don't expect a miracle. Just because your drain is clogged doesn't mean it can open the drain. This is to prevent the accumulation from being stopped in the first place. Do not use corrosive drain openers on cast iron drains. Is always. Use a snake or hire a plumber. Trust me after buying a 40 year old home where the previous owner used drainage products every month for decades. I live with a rusted drainage system. It destroyed my foundation. In fact, do not buy an old house with a cast-iron sewer. The cost of new gutters and a repaired foundation will turn your old house into a money hole.
