"I called Rescue Rooter to come out and clear out a blockage in my sewer line. Chad and Albert came out quickly and got to work. They also put a camera down into the sewer line and had me watch as they went through the line. I saw the various problems in our one hundred year old sewer line. They spent a good deal of time examining the sewer line and also identifying the spot where it becomes a shared line with our neighbor. They presented a number of options of how to repair the deteriorating sewer line along with the different prices for that work. Chad and Albert both explained the different options clearly to my wife and I. They were very friendly and professional."

"Our downstairs toilet, shower and sinks were backing up. We called Drain Pro and they arrived shortly after to look at the problem. They scoped the sewer line with a camera and found a big blockage that was caused by roots. They were able to clear the blockage. Everything is now working great. We will have them back in the future to re pipe the area where the roots have started coming thru. This company is great!!!"

"Pipers contacted us by phone immediately after we submitted a repair request on Labor Day late morning for a clogged sewer line. We set up an appointment for early evening, at which time I mentioned we had intended to celebrate family birthdays that evening. About an hour later Pipers called and said they adjusted their schedule so they could arrive mid-afternoon, which they did. The back-up was cleared and we were so grateful to be able to join our family that evening. Pipers had to remove and reinstall the basement toilet. They cleaned up the area after the work was completed (the bathroom looked better than when they arrived). A great ending to what was a not so great beginning to Labor Day. We will definitely use Pipers for the more extensive work that needs to be done."

Sewer Cleaning FAQs, answered by experts

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

Toilet paper is the only material that you should flush down toilets. Other items like wipes, paper towels, feminine hygiene products, dental floss, and medications should be disposed of in the trash. Flushing these items can lead to plumbing issues and damage to sewage systems. Grease and cooking oils should also be avoided as they can solidify in pipes, causing blockages. Proper disposal helps prevent clogs and ensures the efficient operation of wastewater treatment systems while protecting the environment.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

You could be smelling sewer gas in your kitchen because of a dry P-trap, clogged vent pipe, or leaking plumbing seals. If you smell a rotten egg odor, check your sink’s P-trap and plumbing connections first. A clogged or damaged vent pipe can trap sewer gas and push it back into your kitchen through the plumbing pipes. Loose or deteriorated seals around drainpipes can also allow sewer gas to leak out. If you can’t find the source, call a local plumber for expert help.

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.
