"Excellent communication via text and email so you know exactly when your service technician will arrive. Tommy and Duncan were very polite and professional. They looked over the main water shutoff valve that I wanted to replace and then explained what they were going to do and how much it would cost. Completed the work promptly and cleaned up the work site before leaving. I would highly recommend DB's Plumbing and Drain!!"

"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."

"Gave 5 stars / 10's on grade scales and following comment: Everyone I've dealt with at Snell has given excellent service, from the initial phone call to the finished service. They are timely, clean and thorough. Snell installed our new HVAC system in January 2016. Recent service was just for a seasonal check and filter change. Technician Carl was knowledgeable, helpful, friendly, answered my questions to my satisfaction. I highly recommend Snell."

Drain Cleaning FAQs, answered by experts

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

If the drain is frozen, the pipes connecting to the washing machine are likely frozen. If the hot water trick doesn’t also unfreeze the washing machine pipes, you can gently apply heat with a hair dryer on the lowest setting. Start at the end of the pipe closest to the faucet to prevent pressure from building in the pipes, and make sure the faucet is open to drain the water as it melts.

Pouring drain cleaner down a vent pipe isn’t recommended. First of all, unlike a clog in a sink or bath caused by such material as soap scum build-up, toothpaste, and hair, clogs in a vent pipe are likely the result of debris from trees or even an animal stuck in the pipe. Drain cleaners won’t be able to eat through this kind of material. The cleaner will only become clogged in the vent with the debris, causing even more problems.
