If your home is experiencing discolored water, chronically low pressure, or leaks that keep coming back, the problem may not be the fixtures but the pipes themselves. At TennCo. Plumbing, we specialize in repiping homes across West Tennessee, replacing aging and failing plumbing systems with Uponor PEX-A, one of the most durable piping materials available today.
Some plumbing problems are isolated to a single fixture or line, but others point to a broader issue with the system as a whole. Signs that your home may be a candidate for a full repipe include:
If you are experiencing one or more of these issues, a professional assessment is the right first step.
These conditions are common in the older homes around Jackson and in the established neighborhoods of Paris, and Lexington where aging CPVC and galvanized lines are a frequent source of recurring leaks.
TennCo. Plumbing installs Uponor PEX-A for all residential repipe projects. PEX-A is widely regarded as the highest-performing variant of PEX piping, offering superior flexibility, freeze resistance, and long-term durability compared to traditional copper or galvanized steel. It is also less prone to scale buildup and corrosion, making it particularly well-suited for the water conditions common across West Tennessee.
Most repipe calls come down to one of three aging materials. Knowing which one is in your home tells you a lot about why you are seeing problems and how urgent they are.
Common in homes built through the 1950s and 1960s, galvanized pipe is steel coated in zinc. The zinc erodes over the decades, the exposed steel rusts, and the rust builds up inside the pipe. That buildup is what causes the slow pressure loss and the brown or rust-tinged water many older homes deal with. Because the corrosion happens from the inside, a galvanized system can look fine on the outside while it is closing itself off internally. Once one section fails, the rest is usually not far behind.
Installed widely between the late 1970s and the mid 1990s, polybutylene is a gray plastic pipe, sometimes blue or black, that was used in millions of homes before its failure rate became clear. It grows brittle over time and can fail at the fittings or along the pipe itself, often without warning. Many insurers now flag or decline to cover homes that still have it. If you have gray plastic supply lines, replacement is the safe move rather than waiting for a leak.
CPVC is a rigid plastic pipe that holds up reasonably well but becomes brittle with age and is sometimes installed in a diameter too small for the home, which chokes water pressure at the fixtures. When we repipe a home with undersized CPVC, the pressure improvement is usually immediate and obvious.
Whatever currently supplies your home, we replace it with Uponor PEX-A, a flexible, corrosion-resistant system rated to last decades. If you are not sure which material your home has, that is one of the first things we identify during the assessment.
A whole house repipe is one of the most impactful upgrades you can make to your home. Contact TennCo. Plumbing to schedule an assessment and receive a detailed, upfront estimate before any work begins.
A whole house repiping on a two-bathroom home with a crawlspace starts at $5,500. What moves the number is the number of bathrooms and fixtures in the home. You get the number before the work starts, and it does not change unless the scope changes.
PEX-A is the highest tier of cross-linked polyethylene plumbing pipe. It is manufactured using the “Peroxide” method, which gives it a cross-linking degree of around 80%. This makes it significantly more flexible, durable, and kink-resistant than standard PEX-B pipes. It won’t corrode like copper, pit from hard water, or degrade from chlorine, making it the premier choice for modern residential water lines.
Yes, absolutely. PEX-A is thoroughly tested and certified to meet strict NSF/ANSI Standards 14 and 61 for potable water safety. It is completely non-toxic, lead-free, and does not transfer any chemical taste or odor to your water. Because it resists scale buildup, it also helps prevent the bacterial growth that can sometimes form inside older, corroded metal pipes.
In most standard-sized homes with a crawl space, the entire plumbing installation and repressurization can be completed in just one full workday. Because our technicians can easily run the main lines through your crawl space beneath the house, the installation is incredibly efficient. We complete the entire job from start to finish in a single day so your home life experiences minimal disruption.
Yes, your water will be turned off for the duration of the installation workday. Because we fully demo and replace your old, existing water lines to the fixtures, the main water supply must remain off while our team is working under the house. However, we work efficiently to ensure that your brand-new PEX-A system is fully pressurized and your water service is completely restored by the evening of that same day.
While copper has been the industry standard for decades, PEX-A offers several distinct advantages:
Shape memory is a unique feature exclusive to PEX-A. It uses cold-expansion fittings: we expand the PEX-A pipe and a matching PEX ring, insert a brass or polymer fitting, and let the material naturally shrink back down to its original size. The pipe literally compresses itself around the fitting with immense force, creating a permanent, watertight seal that actually grows stronger over time. If the pipe gets kinked during installation, a quick flash of heat from a heat gun allows it to shrink back to its perfect, original shape without losing any structural integrity.
Rarely. Because the new lines run under the house, a majority of the work happens in the crawlspace, and having to remove any drywall is highly unlikely. In some homes we cut a single access panel to reach the valve behind a tub or shower. That panel is typically located in a closet where towels and toiletries are kept, out of sight in day-to-day use. It is a clean cut with a finished panel, and we tell you before we start whether your home needs one.
Under standard residential conditions, PEX-A has an exceptional operational lifespan and is designed to last up to 50 years. However, just like copper, CPVC, or any other piping material, the exact lifespan can vary depending on your local water quality. Factors like high chlorine levels, heavy mineral content, or extreme pH imbalances can impact the longevity of any plumbing system over time, but PEX-A remains one of the most resilient options available against harsh water conditions.
From a leaky faucet to a full repipe, our team handles residential plumbing across West Tennessee with upfront estimates on every job.
