The best way to prevent clogged pipes and drain blocks is to watch religiously what is going down the drains. Use filters on shower and tub drains to catch hair and other objects. Similarly, sinks can have a trap installed to catch debris. Do not put grease, oil or any foreign objects down the drain. Only toilet paper should go into the toilet. Use compost bins, recycling and garbage to your advantage to keep anything and everything from going down the pipes. Proactive measures are the best way to keep your pipes clear and free of blocks and clogs.
