For minor clogs, you can try pouring baking soda and vinegar down the drain, waiting 30 minutes, then flushing with hot water. Use a plunger over the drain for several minutes to try and dislodge the clog. 

Avoid harsh chemical drain cleaners, as these can damage metal pipes. For best results, we recommend working with a professional plumber.

Signs of a leak include higher water bills, wet spots on floors/walls, musty smells, creaking pipes, and visible pooling of water. If you notice any of these issues, shut off the water line and call a professional plumbing service like A1 Sewer & Drain.

Extreme temperatures and shifting weather strain plumbing in several ways – freezing causes pipes to expand and burst, while big swings in temperature lead to condensation and rust on pipes. Heat can also cause certain pipe materials to contract. This can affect the way water travels through your plumbing lines.
