Professional Drainage Service in Swannanoa
Clogged drains, main line backups and yard water in Swannanoa, traced to the cause by O’Sheas Plumbing.
Inside the Pipe or Stormwater Around the House?
Two kinds of trouble bring people to us for drainage service in Swannanoa: a drain that won’t empty, and water that collects around the house. Telling them apart comes first, because a cable can’t move water that never got into a pipe.
Water backing up through a kitchen sink drain, a tub or the main line cleanout means a clog, and that’s a drain cleaning job. We clean clogged drains and main lines. Water pooling by the house is a different job. Whether it calls for a French drain or a simpler change at the downspouts gets settled once we’ve seen where the water gathers.
On Allen Mountain near Black Mountain, a house partway down the slope takes runoff from the lots above it. When a crawl space there stays wet after every hard rain, the first look goes to where the water’s getting in.
Clean the Main Line or Repair the Pipe?
Once the water’s traced to a pipe, the question is whether a cleaning will keep it open or the pipe has given out. Cleaning keeps a sound pipe flowing, but a cracked, sagging or separated line is sewer work, and our sewer services cover that repair. A drain camera is the step that settles which job you’ve got, before anyone talks about digging. Ian’s there when the line gets opened up and looked at.
We hydro jet lines that grease or roots keep filling back in after a cleaning. On a business line with a grease trap, the trap’s size and hookup decide how often that line’s going to give you trouble.
Sweet Birch Commons, the townhomes on the south side of Black Mountain, was platted in 2018, and its drains are probably PVC. A line there that keeps clogging is more likely a cleaning job than a pipe that’s given out.
Downhill Runoff and Drains in the Swannanoa Valley
The valley tops out at the Swannanoa Gap, near the head of the Swannanoa River. Rain on the slopes below it heads downhill toward houses and the low ground by the river. Water that’s standing against a foundation after a storm is runoff on its way down, and it needs a path that carries it past the house.
Ian owns a sewer camera, a cable machine and a jetter, and the one your line needs comes along once he knows what’s down there. Finding the cause first is what a careful plumber does, because nobody wants a dug-up yard over a clog a cable could clear. “I have had nothing but great experience with this plumber,” Dillon wrote in his review. Every drain call carries O’Sheas Plumbing’s satisfaction guarantee, too.
If you’re still deciding whether a slow drain is worth a call, read up on the signs you need professional drain cleaning first. Call (828) 348-5820 through the night or on a holiday, and tell Sarah whether the water’s coming up inside or pooling outside.
Did you know?
The French drain is named after a person. Henry Flagg French of Concord, Massachusetts, a lawyer and Assistant U.S. Treasury Secretary, described and popularized them in Farm Drainage in 1859, and his name’s stuck to them ever since.
FAQs About Drainage Service in Swannanoa
Drain trouble has a habit of showing up on a holiday weekend, with a full house and the dishwasher half done. Don’t see what you’re looking for? Ask a question here.
Drain cleaning cost in Swannanoa turns on where the clog sits, whether there’s a cleanout to work from and what’s causing it. A kitchen sink clog is a smaller job than a main line packed with grease or roots. Long or older lines take more time, and after-hours calls add to it. O’Sheas Plumbing will tell you what it found before any bigger work.
Rain-driven backups usually mean stormwater is getting into the sewer through a cracked line or a bad joint. Across MSD of Buncombe County’s system, about 40% of the flow is infiltration and inflow, much of it rain and groundwater. When the line is already partly blocked, that extra water has nowhere to go. A camera inspection shows where the water is getting in.
A cable machine, or drain auger, punches through a clog and opens a path. Hydro jetting sends high-pressure water around the whole pipe wall, scouring off grease and cutting roots. Around Swannanoa, snaking suits a simple clog in a sink or tub line. Jetting suits grease buildup or root intrusion in a main line, as long as the pipe is sound enough to take it.
Enzyme cleaners are gentle and fine for routine upkeep, though they work slowly and won’t clear a hard clog. Harsh chemical drain openers can damage older cast iron and galvanized lines, and they sit in the trap if they fail. A cable machine or hydro jetting clears the line without that risk. Call O’Sheas Plumbing when a drain stays slow.
Water backing up in a tub or floor drain when you flush or run the washer is the classic sign. Gurgling in several fixtures at once and slow drains on every floor point the same way. One slow sink is usually a branch clog, while several at once usually means the main. O’Sheas Plumbing clears main lines through the main line cleanout when one is there.
Kitchen sink drains clog from grease buildup that cools and hardens, catching food scraps as it narrows the pipe. Tub drains clog from hair and soap scum. If a drain keeps coming back after it’s cleared, the buildup may be deeper in the line or the pipe may be sagging or rough inside. Ian finds out which before recommending anything bigger.
You might, if water pools against the foundation, soaks a crawl space or runs off a hillside toward the house. A French drain moves that stormwater away through a gravel trench and perforated pipe. On sloped lots around Swannanoa, runoff from uphill is a likely source. O’Sheas Plumbing can tell you whether a French drain fits or a simpler downspout fix will do.
Yes. A drain camera runs down the line and shows roots, grease, a sag, a broken joint or a collapsed section on screen. It turns a guess into a clear answer before anyone digs or replaces pipe. For repeat clogs in Swannanoa homes, a camera look after cleaning tells you whether the line itself is the problem. Ian walks you through the footage.
A Swannanoa basement floor drain smells when its P-trap dries out and sewer gas comes up through the opening. Pour a gallon of water down it every few weeks, or have a trap primer installed if it’s never used. If it still smells, the trap may be cracked or the vent blocked. O’Sheas Plumbing checks both.
Yes, and older lines around Swannanoa and Asheville are where it happens. Roots find their way into cracked joints in clay and cast iron pipe, then grow into a mat that catches everything. Grovemont’s lines date to the 1920s and Parkway Forest’s to the early 1960s, and joints that old can let roots in. Hydro jetting cuts roots out, and a camera shows whether the pipe needs repair.
