As the real estate market gets tighter and more expensive, more and more new homeowners are forced into buying older homes. While they may have their charms, houses and apartments past a certain age have their share of hidden costs — and even dangers.
Most aspiring home owners know about the possibility of finding asbestos in older buildings. A severe health risk and known carcinogen, asbestos can be hard to spot, and difficult (and expensive) to safely remove. But there’s another, less well-known building material that can be just as dangerous: Poly B plumbing.
We’ve encountered poly B pipes quite a few times here at the Home Insurance People. Finding them on your property isn’t ideal, but don’t let it keep you up at night — there are ways to protect yourself and your home, both in the short and long term.
Read on to learn a little more about what poly B plumbing is, why it’s a problem, how it might affect your home insurance, and what you can do about it.
What is Poly B Plumbing?
“Poly B”, also known as PB-1, is short for polybutylene, a form of polymer pipes that were used in new homes constructed from about the 1970s up until the early 1990s. They were cheap, they were flexible, and they were easy to install – much easier than copper.
Fast forward to 2021, and homes that were built with poly B plumbing are having problems. Poly B pipes are less durable than copper, and they tend to deteriorate on the inside while looking normal on the outside – until they start to leak. Leaks which are often further hidden behind drywall.
When these leaks go unnoticed, the resulting water damage often weakens structures and can prompt the growth of mildew and the spread of toxic black mold, which can cause serious health problems for you and your family.
Unfortunately, poly B plumbing is no friend to your home insurance, either. Its presence in your home can often raise your expected insurance premiums – which is all the more reason to speak with an experienced agent right away, to learn about your options and how you may be able to negotiate with your insurance company.
How to Tell If You Have Poly B Pipes
If you had a home inspection carried out before you bought your house, the inspector may have noted the presence of poly B pipes in their report. If they didn’t, or you didn’t have a home inspection done (it happens), look for exposed plumbing inside your home.
Check under your sink, the connections to your water meter, your hot water tank, and any unfinished areas with a water source (such as a basement).
Poly B pipes are often grey, although they can also be black, white, blue, or other colours. They have a bendable, plastic-like texture, and typically have plastic or copper fittings along the length of the pipe. A dead giveaway is if they have the codes ‘PB-2110’ or ‘CSA-1 137.8’ printed on the sides.
Unfortunately, if your home was built between the early 1970s and early 1990s, you could still have poly B plumbing hidden within your walls — it isn’t uncommon to see houses with a mix of metal and poly B pipes. If you think that your home could at all be at risk, it’s best to call a professional plumber and arrange for an inspection.
What To Do About Poly B Plumbing: Short-Term Options
So you’ve found poly B plumbing inside your home. Now what? If you’re on a budget, there are some short-term fixes you might consider:
- Replace any plastic fittings with copper fittings
- Reduce your home’s water pressure
- Lower your water’s chlorine levels
- If possible, reduce any heat sources located near poly B pipes
You may have noticed that all of these options center around the durability of poly B pipes. By reducing the stressors that most commonly cause them to deteriorate, you’ll ideally slow the rate at which they break down – and leak.
Keep in mind that it’s best to speak with a plumber before attempting any of these options, especially those that affect water pressure or quality.
What To Do About Poly B Plumbing: Long-Term Solutions
Short term solutions may work as a ‘band-aid’ option, but poly B pipes can be problematic. If or when you have the budget, it’s best simply to replace them entirely with PEX or copper pipes instead.
If we’re honest, this will most likely have to happen at some point. Sooner or later poly B pipes will damage your home, your health, and pack a sting on your home insurance too.
Replace them as soon as you can. It’s an investment that will pay off in the end: for both your home, and your bank account.
