What Are Polybutylene Pipes and Why Should You Care?
Here’s the thing about polybutylene pipes — they seemed like a great idea back in the day. Builders loved them between 1978 and 1995 because they were cheap and easy to install. But now? They’re basically ticking time bombs in millions of homes across the country.
If your house was built during that window, you might have these gray plastic pipes running through your walls right now. And honestly, that’s a problem you can’t ignore. These pipes degrade from the inside out, meaning they can look perfectly fine while secretly falling apart. When they finally burst, you’re looking at serious water damage, mold issues, and repair bills that’ll make your eyes water.
For homeowners dealing with older plumbing systems, getting a professional assessment is really the first step. Residential Plumbing Services in Redmond OR can help you determine exactly what type of piping you have and create a replacement plan that fits your timeline and budget.
How to Identify Polybutylene Piping in Your Home
So how do you actually know if you’ve got these problem pipes? It’s actually pretty straightforward once you know what to look for.
Check These Spots First
Start with the easy places — your water heater, under sinks, and where pipes come through walls. Polybutylene pipes are typically gray, but they can also be blue or black. They’re about half an inch to one inch in diameter and have a dull, plastic appearance.
Don’t confuse them with PEX pipes, though. PEX is the newer, safer stuff that’s actually flexible. Polybutylene is more rigid and has a different texture. If you’re not sure, snap a quick photo and show it to a plumber. They can tell in about two seconds.
Check Your Home Inspection Report
If you bought your home recently, dig out that inspection report. Good inspectors flag polybutylene pipes because they know the issues. Residential Plumbers Redmond OR see these pipes constantly in homes from that era, so they’re pretty familiar with the telltale signs.
According to Wikipedia’s information on polybutylene, these pipes were installed in an estimated 6 to 10 million homes in the United States, making this a widespread concern for homeowners with properties built during that period.
Why Polybutylene Fails and What It Means for Your Insurance
Alright, let’s talk about why these pipes are such a headache. The chlorine and other oxidants in municipal water supplies basically eat away at polybutylene from the inside. It happens slowly over years, and you won’t see it coming.
The Failure Pattern
Most polybutylene pipes start showing problems after about 10 to 15 years. But here’s the kicker — some last much longer before they suddenly fail. There’s no real way to predict when yours might give out. The fittings are usually the first to go, but the pipes themselves can crack and split too.
When homeowners need guidance on their options, professionals like Speedy Plumbing LLC recommend getting a full inspection before making any decisions. That way, you know exactly what you’re dealing with.
Insurance Complications
Now for the really fun part. Many insurance companies won’t cover homes with polybutylene pipes. Or they’ll cover you but charge way higher premiums. Some will require you to replace the pipes before they’ll even write a policy.
If you’re trying to sell your home, this becomes a huge issue. Buyers get scared off, or they demand major price reductions. It’s kind of a mess either way.
Complete vs Partial Repiping: Making the Right Choice
When it comes to fixing polybutylene pipes, you’ve got two main options. And honestly, the right choice depends on your specific situation.
Partial Replacement
Some homeowners try to save money by only replacing the most accessible pipes or the ones showing obvious problems. This can work as a temporary measure, but it’s sort of like putting a bandaid on a bigger wound. The remaining polybutylene pipes will eventually fail too.
Partial replacement might make sense if you’re planning to sell soon anyway, or if budget constraints are really tight right now.
Complete Repiping
For most situations, complete repiping is the smarter long-term play. Yes, it costs more upfront. But you’re solving the problem once and for all. Modern PEX or copper piping will last decades without the same failure risks.
Here’s a quick comparison:
| Option | Pros | Cons |
|---|---|---|
| Partial Replacement | Lower initial cost, faster completion | Remaining pipes still at risk, may not satisfy insurers |
| Complete Repiping | Permanent solution, improves home value, satisfies insurance | Higher cost, longer project timeline |
Timeline Expectations for Whole-House Replacement
So what should you actually expect if you go the full repiping route? Residential Plumbers near Redmond typically complete whole-house repiping in 2 to 5 days, depending on your home’s size and layout.
The Process Breakdown
Day one usually involves accessing the pipes, which means cutting into some walls and ceilings. It sounds scary, but experienced plumbers minimize the damage. They know where to cut and how to do it cleanly.
Days two through four are the actual pipe installation. The crew runs new lines, connects everything to your fixtures, and tests for leaks. You might be without water for portions of each day, so plan accordingly.
The final day involves cleanup and any patching they can handle. You’ll still need to get the drywall repaired and repainted afterward, but that’s usually a separate project.
Factors That Affect Timeline
- Home square footage and number of bathrooms
- Whether pipes run through concrete slabs
- Accessibility of existing plumbing
- Permit requirements in your area
- Material availability at the time of service
Temporary Fixes vs Permanent Solutions
Look, I get it. Full repiping is expensive. But temporary fixes for polybutylene really are just that — temporary. You can repair individual leaks as they happen, but you’re basically playing whack-a-mole with your plumbing.
The stress of wondering when the next leak will happen isn’t worth it. And the cumulative cost of emergency repairs, water damage restoration, and higher insurance premiums adds up fast. Most homeowners who initially try the temporary route eventually wish they’d just done the full replacement from the start.

Frequently Asked Questions
How much does complete repiping typically cost?
Whole-house repiping generally runs between $4,000 and $15,000 depending on home size, pipe material chosen, and regional labor rates. PEX is usually cheaper than copper but both are solid long-term options.
Can I stay in my home during the repiping process?
Yes, most homeowners stay in their homes during repiping. You’ll have water service interruptions during work hours, so fill some jugs beforehand. The noise and dust are manageable for most people.
Will my homeowner’s insurance cover pipe replacement?
Generally, no. Insurance covers damage from burst pipes but not the proactive replacement of problem materials. However, some insurers offer discounts after you’ve completed the work, so it’s worth asking.
How do I know if my pipes are polybutylene or PEX?
Polybutylene is rigid and typically gray, installed before 1995. PEX is flexible, usually red or blue, and installed in newer homes. If you’re unsure, Residential Plumbing Services in Redmond OR can quickly identify your pipe type during an inspection.
Should I replace polybutylene pipes if they haven’t leaked yet?
Honestly, yes. Polybutylene pipes fail unpredictably and the damage from a burst pipe far exceeds replacement costs. Proactive replacement also helps maintain home value and insurance coverage.
