Most chemical drain cleaners are very toxic in nature. They’re not only harmful to the environment, but also especially dangerous to keep around the home if you have children or pets. Chemical drain cleaning products are very harmful to piping systems as well. Over time these chemicals deteriorate your pipes from the inside out. When this happens, the drain line(s) will have to be replaced. Don’t confuse toxic drain cleaners with the various drain maintenance products that are on the market. These products contain “friendly” bacteria and enzymes. They work to keep drain sludge and grease from building up in the pipes. For more serious clogs, contact the expert plumbers at A.J. Perri.
