GNV Plumbing uses both PEX-A expansion fittings and PEX-B crimp systems depending on the project and budget. Some homes from the late 1970s through the mid 1990s contain polybutylene pipe, which is worth replacing before it fails. When copper lines under a slab start to show pinhole leaks, we reroute new PEX through attics and walls. You get a dependable system without tearing up your slab.

PEX Main Water Line Installation in Millsboro
The main water line brings water into your home, and a failing one can cause major issues. We provide professional PEX main water line installation, replacing old, damaged lines with durable PEX. This upgrade improves water flow, reduces the risk of future leaks and offers superior resistance to ground shifting and corrosion. Our team handles proper trenching and the connection to your municipal supply.
Polybutylene Replacement With PEX in Millsboro, DE
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. Plenty of 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.
PEX-A Expansion Fitting Systems in Millsboro, DE
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 secure seal. The fittings have a larger inner diameter, so flow restriction is lower. PEX-A is also more flexible and can be repaired from kinks with a heat gun. It is our favored choice for many full repipes.
PEX for Remodels & Additions in Millsboro, DE
Expanding your home or remodeling a kitchen or bathroom often requires new plumbing lines. PEX is an ideal choice for these projects in Millsboro, DE due to its adaptability and ease of installation in existing wall cavities or new structures. We can cleanly tie new PEX lines into your current system, ensuring adequate water supply to new fixtures and appliances without compromising your existing plumbing.
PEX for Water Line Replacement in Millsboro
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 Millsboro. PEX main lines handle ground movement and resist corrosion better than rigid pipe. Much of Delaware sits on sandy coastal plain soil with a high water table, which affects slab, crawlspace, and drainage design.

PEX-B Crimp and Clamp Systems in Millsboro
PEX-B is stiffer and more affordable, and it is joined with copper crimp rings or stainless steel cinch clamps over brass or poly fittings. It is a good option for smaller projects and budget-conscious repipes. Brands like Viega, Zurn and SharkBite offer dependable PEX-B systems. We use a go/no-go gauge on every crimp to verify a proper seal.

Frequently Asked Questions About PEX Pipe Installation in Millsboro
The cost of PEX pipe installation in Millsboro, DE varies with the scope of the project, such as a full repipe or a small repair. Generally, homeowners can expect to pay between $3,000 and $10,000 for a whole-home repipe, while smaller projects might range from $500 to $2,000. We provide detailed, transparent estimates before starting any work.
A full home PEX repipe for an average-sized home in Millsboro usually takes 3 to 5 days. Smaller projects or single-line replacements can often be completed in a single day. We aim to minimize disruption and communicate timelines clearly.
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.
Properly installed PEX is expected to last many decades. Manufacturers often offer 25 year warranties when their pipe and fittings are used together.
Small repairs are possible for handy homeowners, but a full repipe requires proper sizing, support spacing and code compliance. Mistakes behind walls can cause hidden leaks and failed inspections.
PEX must be protected from sunlight because UV light breaks down it. Outdoors it needs to be buried, sleeved or completely covered.
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 Millsboro homes. It also reduces water hammer noise.
We install high-quality PEX piping from reputable manufacturers such as Uponor (PEX-A), Viega (PEX-B) and Zurn (PEX-B). We also work with other trusted brands like SharkBite for fittings, so the best materials are used for your installation.
