PEX-A, such as Uponor, uses an expansion tool to stretch the pipe and a ring over the fitting, which then shrinks back into a tight seal. The fittings have a larger inner diameter, so flow restriction is lower. PEX-A is also more flexible and can recover from kinks with a heat gun. It is our preferred choice for many full repipes.

Full Home PEX Repiping in Auburn
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 We remove outdated galvanized, copper or polybutylene pipes and replace them with durable PEX, upgrading your entire water delivery system.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 ends the rust-colored water often seen with older piping in Auburn.
Copper to PEX Conversions in Auburn
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Soft water can be mildly corrosive to copper over time, which sometimes shows up as pinhole leaks in older supply lines. Once a home has had several pinhole leaks, more often follow. Converting to PEX stops the cycle and reduces the risk of hidden water damage. We use approved transition fittings wherever new PEX connects to existing copper stubs or valves.
Polybutylene Replacement With PEX in Auburn, WA
Gray polybutylene pipe was common in homes built from the late 1970s through the mid 1990s and is notorious for sudden failures. Chlorine in municipal water breaks down the plastic and its fittings over time. Many insurers now ask about polybutylene when writing a policy. Replacing it with PEX removes that risk and can make your home easier to sell and insure.
Remodel and Addition PEX Rough-In in Auburn
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 Auburn
When your main water line from the street to your home needs replacement, PEX is an excellent option. Its flexibility allows for easier trenchless or minimal-dig installations, limiting disruption to your yard in Auburn. PEX main lines handle ground movement and resist corrosion better than rigid pipe. Crawlspaces and basements are both common in Washington homes, and a damp crawlspace is often the first sign of a drainage or plumbing problem.
