Full Home PEX Repiping in St. Louis
If your home has old, corroded or leaking pipes, a full home PEX repipe can greatly 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 We remove outdated galvanized, copper or polybutylene pipes and replace them with durable PEX, upgrading your entire water delivery system.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 St. Louis.

Polybutylene Replacement With PEX in St. Louis, MO
Gray polybutylene pipe was common in homes built from the late 1970s through the mid 1990s and is known 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.
Commercial PEX Pipe Installation in St. Louis
Beyond residential work, FGV Plumbing also provides commercial PEX pipe installation for businesses in St. Louis. PEX offers many advantages for commercial properties, including durability, resistance to harsh chemicals and cost savings on installation. We work efficiently to minimize disruption to your business during any commercial plumbing upgrade or new installation.
PEX-A Expansion Fitting Systems in St. Louis, MO
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 be repaired from kinks with a heat gun. It is our favored choice for many full repipes.
Emergency PEX Pipe Repair & Installation in St. Louis, MO
While PEX is highly durable, unforeseen circumstances can sometimes lead to damage. If you have a PEX pipe issue or need an emergency repair or replacement in St. Louis, MO, FGV Plumbing is here to help. Our emergency service makes sure any burst or damaged PEX lines are promptly repaired or reinstalled to limit water damage and restore your plumbing. We carry common PEX sizes and fittings to expedite repairs.
PEX-B Crimp and Clamp Systems in St. Louis
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 solid option for smaller projects and budget-conscious repipes. Brands like Viega, Zurn and SharkBite offer reliable PEX-B systems. We use a go/no-go gauge on every crimp to confirm a proper seal.
PEX for Remodels & Additions in St. Louis, MO
Expanding your home or remodeling a kitchen or bathroom often requires new plumbing lines. PEX is an ideal choice for these projects in St. Louis, MO 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 St. Louis
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, reducing disruption to your yard in St. Louis. PEX main lines handle ground movement and resist corrosion better than rigid pipe. Basements are common in many areas, so sump pumps and foundation drainage are an important part of keeping homes dry.

Multiple pinhole leaks, discolored water, low pressure throughout the house and gray polybutylene pipe are common signs. Recurring slab leaks are also a strong reason to repipe overhead.
