Preventative Maintenance on Plumbing Drains- A common reason for kitchen sink drains to back up is grease, even if you don’t pour left over grease from cooking down the drain. Over time, grease from washing utensils and pans will eventually cause grease to form into black sludge in the pipes. To help prevent this, pour a half-gallon of bleach quarterly, down the drain and let it sit for 30 minutes then rinse through thourghly with hot water. Any store bought drain cleaner contains a form of acid, which eventually eats through the pipe especially, if the plumbing system contains galvanized or cast iron pipe. In lavatories, it is better to repeat the same steps but substitute with enzymes. Search “enzyme drain cleaner” to find the best one for your needs.
