  • Polybutylene interacts with certain chemicals in water and has a faster rate of deterioration, resulting in cracks and fitting problems over time.
  • A house with polybutylene pipes may still be worth the investment if the location of the house is worth it, there is plenty of room for negotiation, and you like the house.
  • Regardless of the pros and cons, polybutylene pipes should be replaced sooner or later, and homeowners should make an informed decision before buying a house with polybutylene pipes.

What is Polybutylene Pipe?

Polybutylene pipe, a plastic polymer used for water supply and distribution piping from 1978 to mid-1995, has gained a negative reputation among home buyers due to its multiple plumbing issues and property damage.

The manufacturing process involved extruding the polybutylene resin into pipes through a die, followed by heating and cooling to give it the final shape. The chemical composition of polybutylene pipes is relatively simple, consisting of carbon, hydrogen, and oxygen atoms, with a repeating unit of -CH2-CH(CH3)-.

Although polybutylene pipes were once considered revolutionary for their flexibility, low cost, and ease of installation, they have now become infamous for their susceptibility to leaks and ruptures.

One of the major issues with polybutylene pipes is their interaction with certain chemicals in water, primarily dissolved chlorine, which can lead to cracks and fitting problems due to the reaction over time. Water pressure also plays a role in the faster rate of deterioration in polybutylene pipes.

The damage and deterioration rate is faster in polybutylene pipes, making them an unattractive option for homeowners. It is important to note that a house inspector can inform potential buyers if the house has polybutylene pipes, but some telltale signs are the ‘PB’ lettering, followed by numbers, and blue plastic pipes.

Sellers are mandated to disclose polybutylene pipes in many states, and almost all real estate listing agents require the seller to disclose the use of polybutylene pipes in the property.

Issues with Polybutylene Pipe

The use of certain chemicals in water can lead to deterioration and damage in the pipes, resulting in plumbing issues and property damage. This is the case with polybutylene pipes, which have been known to interact with certain chemicals in water, particularly dissolved chlorine.

Over time, this interaction can result in cracks and fitting problems, leading to leaky plumbing and potential property damage. Additionally, the rate of deterioration in polybutylene pipes is accelerated by water pressure, making them an unreliable choice for water supply and distribution piping.

The issues with polybutylene pipes have also had an impact on homeowner insurance. Due to the high risk of plumbing issues and property damage with these pipes, many insurance companies will not cover homes with polybutylene pipes or will charge higher premiums to do so.

This is an important consideration for anyone considering purchasing a home with polybutylene pipes, as it can significantly impact the overall cost of homeownership. It is important to discuss the potential insurance implications with your insurance provider and factor this into your decision-making process.

Identifying Polybutylene Pipe

One way to determine if a house has polybutylene pipes is to look for the letters ‘PB’ followed by numbers on the pipes.

Another way is to inspect the color of the pipes, as polybutylene pipes are usually blue.

Inspecting techniques such as these can help identify any potential issues with the plumbing system before purchasing the property.

If the house does have polybutylene pipes, it may be worth considering alternative materials such as PEX or PVC pipes.

PEX pipes are a popular choice due to their durability and cost-effectiveness, while PVC pipes are known for their resistance to corrosion.

Ultimately, it is important to weigh the pros and cons of each option and make an informed decision based on your specific needs and preferences.

Replacing Polybutylene Pipe

Replacing polybutylene pipes with alternative materials such as PEX or PVC pipes is a practical solution to mitigate potential plumbing issues and increase the longevity of the plumbing system.

The cost of replacing polybutylene pipes varies depending on the type of material used and the number of fixtures, but it is estimated to range from $1,500 to $8,000 for PEX or PVC pipes and around $2,500 to $15,000 for copper pipes.

PEX pipes are a cheaper and more cost-effective option than copper pipes, and they are quicker to install. Moreover, PEX pipes have a durability of over 100 years and maintain structural integrity even after extreme expansions and contractions.

On the other hand, copper pipes are only durable for 70-80 years and are more prone to bursting when frozen.

When buying a house with polybutylene pipes, homeowners should negotiate with the seller for a plumbing system replacement or a reduction in the selling price to cover the cost of replacing the pipes.

If the seller is willing to replace the pipes, it is essential to ensure that they use a reputable plumbing contractor and materials that meet the plumbing codes and standards.

Homeowners should also consider discussing their options with the insurance company and the listing agent to ensure that the new plumbing system is covered under their policy.

Ultimately, replacing polybutylene pipes with alternative materials such as PEX or PVC pipes is a practical solution that can save homeowners time, money, and potential plumbing issues in the long run.

Considerations for Buying a House with Polybutylene Pipe

Considerations for purchasing a property with polybutylene pipes should involve thorough research and discussion with relevant parties to make an informed decision.

While polybutylene pipes were once a popular choice for water supply and distribution piping, their reputation has been marred by multiple plumbing issues and property damage.

Homebuyers should consider the potential risks and costs associated with owning a property with polybutylene pipes, including potential damage to the home, increased insurance premiums, and the eventual cost of replacement.

One important consideration when purchasing a property with polybutylene pipes is insurance coverage. Homeowners may find it difficult to obtain insurance coverage for a property with polybutylene pipes due to the increased risk of water damage. It is important to discuss insurance options with the home owner’s insurance company to ensure that the property can be adequately insured.

Additionally, negotiating options may be available to homebuyers who are willing to purchase a property with polybutylene pipes. Some sellers may be willing to negotiate on the price of the home or contribute to the cost of replacing the pipes.

Homebuyers should carefully consider their options and weigh the potential risks and benefits before making a decision about purchasing a property with polybutylene pipes.
