"I discovered my 10 year old water heater had developed a pretty good leak and called the branch located in Hudson, WI. Brian answered my call and he was very attentive to my needs, quoted me a better price than I was finding elsewhere, and was able to schedule an install in a very short time. I really appreciated his help and understanding of my situation. The install went great and my new water heater is functioning as it should! I'm definitely a repeat customer should the need arise!"

Sewer Cleaning questions, answered by experts

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

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.

While not every clog has the same symptoms, the most common early sign that your main sewer line is clogged is that multiple drains in your home are draining slowly. You may also notice gurgling and odors from drains. If your plumbing system's drain cleanout is backing up with water, this is also a sign of a clog or blockage.
