Drain Pipe Liner | Cast Iron Drain Pipe Repair, Tools & Cost

Drain pipe repair

Drain pipes corrode quickly because they are regularly exposed to running liquid and open air.  Drain pipes can be repaired using epoxy technology which greatly extends their life span.

Drain Pipe Repair

Drain pipes remove sewage from homes and buildings. If the pipe becomes blocked or damaged, sewage will back up into the home or building. The most common warning signs of a leaky or damaged drain pipe are easily clogged drains, unpleasant odors, and soggy spots in surrounding grass.

To repair a drain pipe, you can dig up and replace the entire line. Or, in most cases, you can opt for no-dig drain repair.

This kind of repair uses specialized equipment to insert, place and affix an epoxy pipe lining within the damaged drain pipe. The epoxy is different from that used for indoor copper pipe repair. It is also a separate process from sewer pipe lining repair.

Installing a drain pipe liner is an ideal solution for cast iron drain pipe repair. CuraFlo uses its proprietary Spincast System to create a pipeliner within the damaged drainage pipe. The Spincast System uses centrifugal force to robotically apply epoxy to up to 700 ft. of pipe at one time. This is an example of CIPP (cured in place pipe) repair.

Drain Cleaning Tools

Before a drain liner can be installed, the pipe needs to be cleaned. If the pipes are not thoroughly cleaned before lining, any sort of debris will remain, and get trapped between the pipe and the liner. The three most common ways to clean pipelines are:

  • Plumbing auger
  • Hydro-jetting
  • Sandblasting

Each of the methods above are effective in different scenarios. Some draining lining companies offer only one cleaning method. At CuraFlo, our team determines the right choice after assessing the type and extent of the damage.

Plumbing Auger

The plumbing auger is a basic yet effective drain cleaning tool. It looks like a set of curved blades at the end of a snake. As the auger is moved through the pipe (usually using a motor), the blades turn and remove anything attached to the pipe walls, including tree roots. Anything in the drain will also be pushed forward to the end of the line.


This method of drain cleaning involves using used compressed air to release narrow jets of water at high speeds into the pipe. Like using a Waterpik to clean your teeth, the force of the water removes debris and build-up.


Similar to hydro-jetting, sandblasting requires specialized equipment. Through a nozzle attached to an air compressor, small grains of sand are forced into the pipe. The pressure and force is so great that the sand dislodges anything attached to the inside of the pipe.

Once the drain is clean, the drain pipe lining process can begin.

Drainage Pipe Cost

The cost of drain lining depends on several variables, including:

  • Extent of damage
  • Location
  • Type of pipe

Projects typically have two pricing components: cost per foot of pipe/pipeliner and fixed equipment costs.

Your CuraFlo plumbing professional assesses the situation before preparing a detailed quote and answering your questions. Our team members are knowledgeable about drain lining systems and can demonstrate why our Spincast System produces quick and long-lasting results.
