FAQs
What are polybutylene water lines and why are they a concern in Johnson City homes?
Polybutylene (PB) pipes are a type of plastic plumbing installed primarily between the late 1970s and mid-1990s. Over time, chlorinated water can cause the interior of PB pipes to flake and become brittle, leading to sudden leaks or bursts. Many insurers now refuse coverage for properties that still contain PB piping, making replacement a high priority for Johnson City homeowners.
How can I tell if my house has polybutylene plumbing?
PB pipes are usually gray, sometimes blue or black, and are ½" to 1" in diameter. Look for exposed runs near the water heater, under sinks, or at the main shut-off valve. The pipe may be stamped with "PB2110". Because piping is often hidden behind walls or in crawl spaces, a professional inspection is recommended to confirm whether PB is present.
What materials do you recommend for replacing polybutylene lines?
The two most common upgrade options in Johnson City are PEX (cross-linked polyethylene) and Type L copper. PEX is flexible, resistant to scale and chlorine, and generally less expensive to install. Copper offers excellent longevity and heat tolerance but costs more and may require extensive wall or ceiling access. Our plumbing specialists will review your layout, budget, and water quality to recommend the best choice for your home.
Will I need to vacate my home during a whole-house repipe?
In most cases, no. We plan the project in stages, maintaining temporary water service to one bathroom or kitchen sink whenever possible. Typical single-family homes can be completely repiped in 2–5 days. We protect floors, furnishings, and clean up daily so you can remain comfortably in the residence throughout the upgrade.
How much does a polybutylene pipe replacement cost in the Johnson City area?
Costs vary based on house size, number of fixtures, choice of pipe material, and the amount of drywall repair required. For a 1,600- to 2,200-sq-ft single-story home, PEX repipes usually range from $4,500 to $8,000. Multi-story or copper projects can range from $7,500 to $15,000. We provide a detailed, written estimate after an on-site evaluation, and financing options are available.
Does replacing polybutylene piping add value to my home?
Absolutely. Eliminating PB pipes reduces the risk of catastrophic water damage, lowers homeowners-insurance premiums, and removes a red flag for real-estate inspectors. Many buyers in Johnson City request proof that PB has been removed before proceeding with a purchase, so a repipe can make your property more marketable and increase its resale value.
