Repairing a drain line costs $696 on average, with a typical range of $225 and $1,169. This estimate includes parts and labor to repair or replace a small section of plumbing. The price to install new pipes throughout your home could run to $15,000.

Your home’s plumbing has most likely been a part of your house from the time it was built. Unless you live in a brand-new home, your pipes could be very old.

Cast Iron Drain Pipe Replacement Cost

average cost to repair a drain line is $700 or $100 to $3,500

Replacing your pipes can cost you $200 to as much as $15,000. This range depends on the size of the project, materials used and labor. Some jobs require extensive cutting into walls or flooring, which can dramatically increase the labor time.

Although removing all the plumbing and putting in new pipes can cost the most, sometimes it’s more economical than smaller repairs. If your plumbing is old, shows a lot of signs of wear, or contains harmful elements like lead, your plumber might recommend a full replacement.

New Drain Pipe Cost Per Linear Foot

The price of new drain pipes runs $0.50 to $20 per linear foot. Plumbers usually markup materials by 25% to 50%, totaling a material price range of $0.75 to $30 per foot not including labor.

Plumbing Material Price List
Type Price Per Foot With Markup
Cast Iron $10-$20 $12.50-$30
Copper $2-$10 $2.50-$15
Polyvinyl Chloride (PVC) $0.50-$5 $0.75-$7.50
Polyporpylene (PP) $1-$10 $1.25-$15

Replacing Cast Iron Drain Pipes vs. Plastic

Cast iron pipework runs between $2 to $10 per foot and was the standard until the 1960s. PVC plastic runs $0.50 to $5 per foot and became popular largely due to price. Although cast iron is prone to rusting, it may hold up better than PVC.

Cost to Replace a Drain Pipe Under the House

Replacing a drain pipe could require as much as $2,800, depending on how difficult it is to reach. Your plumber can use a camera to locate the source of the damage if it’s not obvious. A sewer line camera inspection costs $350 and is not included in the $600 average repair cost.

Consult a Plumber for Drain Pipe Replacement

Cost to Replace Drain Pipe in Basement

The price to replace a basement drain averages $1,650. This includes removal and replacement. The total increases if the plumber must cut into the concrete slab, which is common for floor drain installation.

Replacing a sump pump costs $1,200, and your plumber may be able to do both at once.

Shower & Bathtub Drain or Waste Pipe Replacement

The $600 average for line repair can run much higher if the pipe is near the bathtub or shower. This is because it may be impossible to access the pipes without damaging the shower enclosure or tub. Homeowners may also have to pay these expenses:

  • Cost to install shower: $3,400
  • Price to replace bathtub: $3,100
  • In many cases, plumbers recommend replacing these units at the same time as repairing a drain line.

    Kitchen Drain Lines

    Repairing or replacing drain lines in the kitchen can be as low as $100. It runs less than other jobs because the pipes for sinks, dishwashers and refrigerators are often easily accessible inside cabinets. The rate to hire a plumber is $45 to $200 per hour. They usually charge a one-hour minimum, even if the project runs shorter.

    Cost to Replace a House Trap

    Replacing a house trap costs up to $100 in materials, plus up to half a day in labor. Digging under the foundation may require more time to install the trap. Replacing concrete costs extra. The trap connects the drainage system to the sewer lateral. Double-vent traps allow access to both the sewer and drain lines for cleaning.

    AC Drain Pipe

    Flushing out or replacing your air conditioner drain line runs $75 to $250. The cooling process releases condensation into a pipe. If it cracks or gets clogged, your plumber or HVAC technician may recommend replacing it.

    Cost to Repair Drain Line Leaks or Breakage in the Home

    Repairing a drain line ranges from $226 to $967. Broken pipes can come from corrosion, freezing or persistent clogs. The cost to clear a drain runs $215 on average and may be more appropriate to repair blockage.

    Sewer Line Repairs in the Yard

    Repairing a sewer line costs about $2,600. Unlike a drainage system, your sewer main sits many feet underground. The pipes can collapse or encounter damage from tree roots, animal infestations or serious clogs.

    Additional Cost Factors

    If the breakage causes other damage to your home, you might pay for extra services, like:

  • Cost to repair a foundation: $4,100
  • Price to clean up water damage: $2,600
  • Average to remove standing water: $2,900
  • Your plumber may be able to perform some of this work or recommend a professional who can. The best preventative measure you can take is to keep your eyes open for leaks, water damage, or pooling water in your yard. The sooner you catch any kind of line break, the less damage there is to repair.

    DIY Repairs vs. Hiring Plumbing Help

    What Does Drain Pipe Lining Cost?

    Trenchless sewer replacement runs between $60 to $250 per foot, but usually is not an option for interior plumbing lines. Plumbers use this approach for outside sewer pipes.

    How Can I Find the Break or Leak in the Line?

    Unless you can see a clog through a drain or a cracked pipe under a sink, you may not be able to visually identify its location. To find the problem, your plumber may test your water pressure at certain points or use a sewer camera.

    What’s the Difference Between a Drain Line and Sewer Line?

    Drain lines run from sinks, bathtubs, showers and toilets to your sewer pipes located underground. The materials for each may be the same. Due to accessibility, repair costs can vary significantly.

    Will the City Pay for Drain Line Breaks?

    Generally, you’ll need to pay to fix pipe problems because they occur on your property. Any damage to your home or land from clogs or breaks in the municipal sewer line may be covered by your city.

    How Much Does It Cost to Repair a Storm Drain?
