"Want to give great praise to David Weinfeldt and staff. I experienced home boiler and pipe issues. Compared to other's Dave gave a excellent and fair price quote. I had other quotes, but Dave stood behind his. I accepted his offer. Omar and William arrived on time. They looked at the task and gave a great resolution. Replacing pipes and boiler work is never easy, especially when working behind walls etc. Omar and William did a neat and professional job. When completed they showed me what was done and offered great maintenance advice. Dawson Mechanical is the way to go."

"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 questions, answered by experts

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.

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.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.
