"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

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

You can pour hot water down your gutter drain to melt ice and keep ice dams from forming. If the problems persist, consider investing in heat cables to run in your gutters. Heat cables can adjust based on the surrounding temperature to keep ice thawed.

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.

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters.
