If you’ve been researching epoxy liners in order to determine if they would work for rehabilitating your aging potable water and drain lines, you’ve probably noticed that some epoxy is blue and some epoxy is red. The primary difference is where the epoxy is placed. Red epoxy is most often used on potable water lines, while blue epoxy is used on drain and sewer lines.
Types of Epoxy
Here at Nu Flow, we use two different types of epoxy, including blue epoxy and red epoxy. While they are extremely similar in composition, they are used in different areas of your plumbing system, depending on whether the pipes are carrying clean, potable water or removing waste from your commercial, residential or industrial building.
- Blue Epoxy
Blue epoxy is blue in color and is often referred to as PIPP or Pull-in-Place Pipelining. It involves soaking a liner in epoxy, inserting (pulling) the liner into the pipe and using a bladder to inflate the PIPP liner until it presses against the host pipe. Once this liner is cured, it operates just like a new pipe. Since blue epoxy contains a liner, it is slightly thicker than red epoxy, which makes it slightly more durable.
Blue Epoxy Pros
- Thicker than red epoxy
- Can be used on drain and sewer lines
- Stops leaks and pipe corroison
- Comes with a 10-year warranty
- Rated to last up to 50 years impotenciastop.com
Blue Epoxy Cons
- Slightly narrows the original diameter of the pipe due to the liner
- Not approved for use in potable water lines due to the felt or fiberglass liner2. Red Epoxy
Red epoxy is red in color and often referred to as Cured-in-Place Pipe (CIPP). This epoxy is a type of coating that is blown through potable water lines in order to seal cracks and prevent future leaks and corrosion. Once the coating as cured in place, clean, potable water flows down the linter instead of the host pipe.
Red Epoxy Pros
- Can be blown into potable water lines
- Minimally affect internal pipe diameter
- Seals cracks and pinholes to stop leaks
- Warrantied for 10 years
- Can last up to 50 years
Red Epoxy Cons
- Slightly less durable than blue epoxy because it does not contain a liner
- Can’t be blown into pipes that have collapsed
- Can’t be blown into pipes that cannot withstand the pipe cleaning and preparation process
