Your Go-To Choice for PEX Pipe Installation in Bismarck, ND
HPN Plumbing focuses on PEX pipe installation, offering Bismarck homeowners a modern and durable alternative to traditional plumbing materials.

Frozen pipes are a serious and regular winter risk in North Dakota, and a single cold night can split a line in an exterior wall.
Our expertise includes:
- PEX-A expansion and PEX-B crimp fitting systems installed
- Manifold and home-run layouts with individual fixture shutoffs

Polybutylene Replacement With PEX in Bismarck, ND
Gray polybutylene pipe was common in homes built from the late 1970s through the mid 1990s and is known for sudden failures.

Replacing it with PEX removes that risk and can make your home easier to insure and sell.

A small repair or extension might take a few hours, while a complete whole-home repipe for an average-sized house in Bismarck typically takes 2 to 5 days. We work efficiently to limit disruption to your daily routine.
PEX resists scale and corrosion, flexes with temperature changes and has far 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 commonly offer 25 year warranties when their pipe and fittings are used together.
Yes, for significant plumbing work like a full home repipe or new water line installation in Bismarck, a plumbing permit is usually required. HPN Plumbing handles all necessary permits and makes sure our work complies with local building codes and inspections.
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.
While PEX is simpler to install than copper, professional installation is strongly recommended. Correct sizing, routing and secure connections are crucial for preventing leaks and ensuring system longevity. Improper DIY installation can lead to costly water damage and code violations.
