"We had a great experience with Giant Plumbing and couldn't be happier with the outcome. After a previous water line repair by another company didn't meet our criteria, code, or accepted plumbing standards, Don carefully evaluated the situation, clearly explained what needed to be corrected, and handled everything professionally from start to finish. They fully removed the prior work, rebuilt the system to code, and completed the job exactly to our specifications. Their communication was excellent throughout -- thoughtful, transparent, and never rushed -- and the quality of workmanship was outstanding. The final result is clean, secure, and exactly what we had hoped for from the beginning. It was a huge relief to work with a licensed professional who takes pride in doing things the right way. We would absolutely recommend them and wouldn't hesitate to hire them again."

French Drains FAQs, answered by experts

Professionals use augers, hydrojetting equipment, and cameras for precise clearing and inspection.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

Drain fly problems can go away on their own—but only if the insects find the environment inhospitable. Those with a minor infestation can simply flush their toilets and run their faucets more frequently to flush out the flies and larvae. Others will have to deep clean their drains and set up traps.
