Understanding Poly B

Poly B is a type of plastic plumbing pipe that garnered popularity that spanned through the 1970s to the 1990s. It was widely used in residential and commercial constructions due to its low cost, flexibility, and ease of installation. However, over time, several significant problems emerged with Poly B piping, where homeowners are at a greater risk of household leaking and property destruction, ultimately leading Poly B piping to an eventual decline in popularity.

Signs of Poly B Usage:

  1. Gray or blue piping: Poly B pipes are typically gray in colour, although a less common variant is blue. If you notice these colours in your plumbing system, especially in exposed areas such as the basement or utility room, it may indicate the presence of Poly B piping.
  2. Stamped markings: Poly B pipes often have stamped markings on them, indicating the manufacturer and relevant information. Look for the term “PB” or “Poly B” on the pipes, as this can be a clear sign of their presence.
  3. Plastic fittings: Poly B pipes are typically joined using plastic fittings, which are distinct from the metal or copper fittings commonly used with other plumbing materials. Plastic fittings can be a visual clue to the use of Poly B piping in your home.
  4. Leaks and water damage: One of the most significant issues associated with Poly B piping is its susceptibility to leaks and subsequent water damage. If you notice recurring leaks or signs of water damage, such as discoloured walls, ceilings, or musty odours, it could be an indication of problems with Poly B pipes.
  5. Pinhole leaks and corrosion: Poly B pipes have been known to develop pinhole leaks over time, particularly in areas with high chlorine levels in the water supply. These leaks can lead to corrosion and deterioration of the pipe, compromising its structural integrity.

Implications of Poly B Usage:

  1. Potential for water damage: Due to its vulnerability to leaks, Poly B piping poses a higher risk of water damage to your home. A leak can cause significant property damage, leading to mould growth, structural issues, and costly repairs.
  2. Insurance complications: Some insurance companies have restrictions or limitations when it comes to homes with Poly B piping. It’s important to check with your insurance provider to understand their policies and any potential implications for your coverage.
  3. Decreased property value: The presence of Poly B plumbing can negatively impact the value of your home. Prospective buyers may be wary of purchasing a property with this type of plumbing due to its history of problems and associated repair costs.
  4. Replacement considerations: If you have Poly B piping in your home, it is worth considering replacement options. Replacing the plumbing system with more reliable materials, such as copper or PEX, can provide peace of mind and potentially increase the value of your property.
