This is a great question many homeowners have once they’ve dealt with the inconvenience of a clog. The most important thing to do is take preventative measures to reduce the number of materials going into the sewer that shouldn’t be washed or flushed down a drain. For instance, flushing wipes down the toilet or dumping grease and oil down the kitchen sink. Oil and water do not mix and as a result the oil builds up over time in your drains and a clog-prone environment is created. Flushable wipes are usually marketed as being safe for plumbing, but this is untrue as repeated usage of these wipes frequently results in obstructions. Your drains and sewer system will last longer if you take these precautionary steps to keep unnecessary items out of the wastewater system.
