Full Home PEX Repiping in Wentzville
If your home has old, corroded or leaking pipes, a full home PEX repipe can drastically improve your plumbing system. We remove outdated galvanized, copper or polybutylene pipes and replace them with durable PEX, upgrading your entire water delivery system. This prevents future leaks, improves water pressure and eliminates the rust-colored water often seen with older piping in Wentzville.
Remodel and Addition PEX Rough-In in Wentzville
Kitchen and bathroom remodels are a good time to replace old supply lines with PEX. We rough in new lines to the correct heights for vanities, showers, tubs and appliances, then pressure test before the walls are closed. Additions and guest suites get correctly sized lines tied into your existing system. We coordinate with your contractor to keep the project schedule on track.
PEX for Water Line Replacement in Wentzville
When your main water line from the street to your home needs replacement, PEX is an smart option. Its flexibility allows for easier trenchless or minimal-dig installations, reducing disruption to your yard in Wentzville. PEX main lines handle ground movement and resist corrosion better than rigid pipe. Basements are common in many areas, so sump pumps and drain tile are an important part of keeping homes dry.
PEX-A vs. PEX-B Installation in Wentzville
We offer installation for both PEX-A and PEX-B piping and understand the different advantages of each. PEX-A, often preferred for its flexibility and ability to recover from minor kinks, uses expansion fittings. PEX-B is more rigid but also very durable, usually using crimp or compression fittings. Our plumbers in Wentzville can help you decide which type of PEX suits your project, considering factors like budget and application.
Manifold and Home-Run PEX Layouts in Wentzville, MO
A manifold system sends a dedicated line from a central hub to each fixture, similar to a breaker panel for water. Each line gets its own shutoff, which makes repairs easier and keeps pressure steady when multiple fixtures run. Home-run layouts use more pipe but fewer fittings in walls. We often combine manifold and trunk-and-branch designs to weigh cost and performance.

PEX resists scale and corrosion, flexes with temperature changes and has fewer joints. Copper is very durable but can develop pinhole leaks in some water conditions and costs more to install.
PEX offers several advantages over copper, including lower material and installation costs, greater flexibility and resistance to corrosion and freezing. Unlike copper, PEX does not develop pinhole leaks over time due to water chemistry, making it a more durable choice for many Wentzville homes. It also cuts down on water hammer noise.
We install Uponor PEX-A along with Viega, Zurn and SharkBite PEX-B systems. We recommend the system that suits your project and budget.
Most whole-home PEX repipes take two to four days. Larger homes or difficult attic access can take a bit longer.
