"The sinks are draining well. The stopper is fixed. The toilet was unclogged, but got clogged again the next day. Had to pour Ajax, and let it sit overnight to unclog the toilet again. That is the reason I have given a B, rather than an A"

"Drytech contacted me about my inquiry for a drain system in my driveway. We set up a date and time. The company called the day before â to confirm the time. The representative arrived on time. We discussed the issues w/ my driveway, and my concerns. After discussions he told me that I probably did not need a drain system. While he did not complete any work for based (because of his honesty) I was impressed with his questions, the time he spent with me and how pleasant he was. He left me his card and informed me what issues to look for."

"Alex was very responsive and we made an appointment for him to look at our driveway to give us a quote. He understood our drainage issues immediately and explained thoroughly what needed to be done to fix it permanently barring any biblical deluge. Alex got back to us quickly with a written quote that was very reasonable. We have decided not to go ahead with this investment at this time, but when we are ready, Alex is our man. We highly recommend him for his knowledge, experience, and prompt response time."

"Very professional from start to finish! The salesman/ design technician showed up right on time, he listened to my concerns and came up with the solution on the spot! The price was less than expected and the project was done in a very timely manner! The technicians who did the work were also punctual and did a phenomenal job!! Perfect installation of a drain and pump system, fast and neat, cleaned up 100%. The office staff also polite and very efficient! I can not speak for any other services they provide, but for waterproofing, I do not think anyone could do it better!"

Drain Pipe Installation FAQs, answered by experts

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

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.

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.
