"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

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
