Poly B replacement Calgary

What Is Poly B Piping

Poly B or Polybutylene is a flexible plastic piping that was heavily used from 1978 to 1995 in the construction of many homes. You can generally spot poly b piping because of its light grey color and copper or plastic connectors.

Polybutylene piping was incredibly popular because it was a cheaper alternative to copper piping and was installed in roughly 700,000 homes across Canada.

This type of piping is infamous for leaks or bursts.  Here are some common questions we get about Poly B.

Does My Home Have Poly B Piping?

Poly B piping was very popular in homes built between 1978 and 1998. If your home was built before 1975 and has not gone through any major plumbing renovations you should generally be safe.

If your home was built between 1998 and 2005 there is a very low chance that your home is fitted with Poly B plumbing. However, you should still check your plumbing because although the plumbing code has stopped the use of Poly B pipe, that code was not retroactive which means if the pipes were installed they could stay. Also, some plumbers may have had excess Poly B plumbing material that they may have installed.

In Alberta, the government estimates that roughly 148,000 homes in the province are fitted with Poly B plumbing.

Common Issues & Problems With Poly B Plumbing

Poly B is one of the most infamous plumbing materials due to these pipes having an incredibly high rate of failure. These pipes generally do not present an immediate danger, but if or when a leak develops they can cause damage to your home incredibly quickly. If your Poly B pipe happens to be behind a wall or ceiling you can be completely caught off guard.

Poly B piping was widely used when building homes in Calgary and over the years as these homes begin to get older, we are finding that more of these homes are requiring pipe replacements. Although you may have these pipes in your home and they may not have caused any issues, they will eventually begin to leak and cause extensive damage to your house which will require significant work down the road.

Some common problems that you may have with Poly B are:

  • Improper installation from a plumbing company may result in the pipes being under too much stress because they may have been installed too tightly. This can result in the pipes developing small hairline cracks which can result in leaks or bursts.
  • Another prime example of improper installation of polybutylene pipe would be putting the pipes under too much pressure. Examples of this would be harsh bends or kinks in the pipe.  This can lead to failure where the pipe wall is compromised.
  • In certain cases rather than using the copper fittings when installing the pipes, some plumbers used acetal fittings to connect the pipes. You can spot these acetal fittings by their white or grey fittings.  These fittings are susceptible to chlorine and will deteriorate over time due to the chlorine in our water.
  • Installs near areas in your home that are exposed to high heat can result in the pipes requiring replacement. Poly B should never be used in high heat areas, so if you notice this in your home call a plumber ASAP to get service.  Even the increased temperature of your domestic hot water can cause leaks in your Poly B piping.
  • Poly B pipes are also permeable to oxygen, so when the piping in your home is carrying hot water they can be extremely hard on your water heater or boiler. This can significantly shorten the lifespan of your plumbing and heating systems.

Over the years many homes in Calgary have replaced their Poly B pipes. Unfortunately, many of these services were not covered through their home insurance companies. If you are hoping that insurance will cover any water damage or plumbing services the chance is very slim.

What Does Poly B Piping Look Like?

You can spot a Poly B pipe in your home by looking for grey plastic piping that has a permanent marking on it that says "poly b potable" or "PB2110" across the pipe.

Be careful not to mistake any other piping with Poly B pipes. Some of your other drain pipes may be made out of black PVC or ABS plastic. You may also find some PEX piping which can be a white or clear/translucent pipe. PEX pipe is the product that usually replaces Poly B. While it can look somewhat like Poly B, PEX has a stronger wall strength and a proven track record. It has been used in Europe for decades with few failures.

Be sure to inspect your plumbing and heating system for pipes that look like Poly B and call in a professional plumbing company for a second set of eyes or to replace Poly B piping.

How Can I Tell If My Poly B Pipe Needs Replacement?

It can be very challenging to determine whether your polybutylene pipe needs to be replaced. This is largely due to the fact that many times damage will occur to the inside of the pipes. The damage occurs because the water supply runs within the pipe. It is highly unlikely your damage would be external unless you are bumping into your pipe and causing damage to the plastic fittings.

For additional peace of mind, you could check your Poly B piping routinely for any leaks or pipe failure. Keeping an eye out will help you spot a leak before it can have time to damage your home. However, we would recommend getting Poly B replaced as soon as you discover it in your house.

In some cases you can find leaks within in-floor hydronic heating systems that use Poly B, this is because Poly B does not handle heat well. Be sure to inspect your Poly B piping thoroughly because your Poly B piping could have a pinhole leak.

If you notice any of the signs we have discussed we highly recommend choosing a plumber to work on your Poly B replacement, our team at Northern Oasis has extensive experience in Poly B service work and leak detection.

How Much Does Poly B Piping Replacement Cost?

Poly B replacement is not as easy to quote as hot water tank or water heater replacement jobs. This is because each service is unique to each home. Before we provide you with a quote for replacement services we need to take a look at the work required in your home.

A rough estimate for each house could be between $1600 to $10,000+. The reason for this huge range is because a Poly B replacement service will generally require drywall removal work.

While we do not perform drywall repairs we can recommend professionals to assist with your renovation.

Can Poly B Be Repaired?

Poly B piping has been discontinued for nearly 15 years so it is unlikely that your pipes will be able to be repaired.  An adapter can be installed to transition to PEX for short term repairs but the best thing that you could do would be to call in a plumber to replace all the Poly B within your home in Calgary. The replacement services would generally use PEX  piping.

PEX piping is much better when handling hot water and water pressure and is not susceptible to heat or chlorine like Poly B or wear from cavitation like copper.
