FAQs
What are the most common causes of persistent main-line blockages in Reliance?
In the Reliance area our technicians most often find four culprits: (1) tree-root intrusion through small cracks or joints in the sewer lateral, (2) heavy grease or food waste that cools and congeals inside the pipe, (3) non-flushable items such as wipes, feminine products, or paper towels, and (4) structural issues like pipe sagging ("bellies") or collapse due to age or ground movement. Any one of these can create a stubborn blockage that simple plunging or chemical cleaners will not remove.
How can I tell if the blockage is in a household drain or in the main sewer line?
A single slow-draining sink or tub usually points to a local fixture clog. When you notice simultaneous problems—water backing up in the shower when the washer drains, gurgling in multiple toilets, or sewage seeping from a basement floor drain—the restriction is almost always in the main line. Another indicator is if every fixture on the lowest level of the home backs up first; gravity makes the main line the common pathway for all those drains.
Will store-bought chemical drain cleaners solve a main-line blockage?
No. Chemical cleaners are designed for minor hair or soap scum clogs close to a fixture’s trap. They seldom reach or dissolve obstructions 10–100 ft downstream in the sewer lateral, and their caustic ingredients can corrode older cast-iron piping and harm the environment. For main-line stoppages, professional mechanical cleaning, hydro-jetting, or sectional pipe repair is the safe, effective choice.
What techniques does Reliance Plumbing use to clear stubborn main-line clogs?
We begin with a video camera inspection to locate and identify the obstruction. Depending on what we see we may employ (1) a heavy-duty sewer auger for roots or hard blockages, (2) high-pressure hydro-jetting to scour grease and scale from the pipe walls, or (3) sectional pipe replacement or trenchless lining if the pipe is damaged or collapsed. Every job concludes with a follow-up camera pass so you can see the restored flow for yourself.
How much does main-line blockage removal cost in Reliance, and is it covered by insurance?
For a straightforward main-line snaking the typical cost in Reliance ranges from $175–$350. Hydro-jetting or root removal averages $400–$650, while pipe repair or trenchless relining can run $1,500 and up, depending on depth and length. Standard homeowners insurance rarely covers line clogs caused by improper use (grease, wipes), but some policies or third-party sewer line warranties will help pay for root intrusion or pipe collapse. We’re happy to provide written estimates for you to submit to your carrier.
How can I prevent future sewer-line blockages?
1) Dispose of fats, oils, and grease in the trash, not the sink. 2) Flush only toilet paper—no wipes, even if labeled “flushable.” 3) If you have mature trees, schedule a yearly camera inspection or root-cutting before growth becomes invasive. 4) Install a backwater valve to stop municipal surges from entering your home. 5) Consider an enzyme-based drain maintenance product monthly; it eats organic buildup without harming pipes. 6) Address slow drains promptly—early intervention is far cheaper than an emergency main-line backup.
