Polybutylene Pipe Replacement in Mandan
Gray polybutylene pipe was installed in many homes from the late 1970s into the mid-1990s. It breaks down from the inside when exposed to chlorinated water, and fittings can crack without warning. Some insurers raise premiums or decline coverage on homes that still have it. We remove polybutylene supply lines and replace them with PEX-A or copper. A completed repipe can also help when listing the home.

PEX Pipe Replacement in Mandan
PEX (cross-linked polyethylene) piping has become a popular choice for residential pipe replacement due to its flexibility, affordability, and resistance to freezing. Frost goes deep into the ground here, so water and sewer lines must be buried well below the surface to avoid freeze damage. Unlike rigid pipes, PEX can expand, reducing the risk of burst pipes during unexpected cold snaps. HPN Plumbing specializes in PEX installation, which often allows for less invasive replacement methods compared to traditional materials. This modern solution offers strong performance and water quality for your home.
Commercial Pipe Replacement in Mandan
Beyond residential services, HPN Plumbing also provides commercial pipe replacement for businesses and properties in Mandan. Commercial plumbing systems often face higher demands and require specific knowledge. Whether it's replacing supply lines in an office building, drainage pipes in a restaurant, or addressing complex industrial piping, our experienced commercial plumbers ensure limited downtime and durable solutions tailored to your business needs.
PEX Repiping in Mandan
PEX-A is flexible, resists scale buildup and expands slightly if water freezes, which helps in colder homes. We use expansion fittings that keep the full inside diameter of the pipe for better flow. Systems can be run as a home-run manifold with a shutoff for each fixture or as a trunk and branch layout. PEX installs faster than copper with many fewer fittings in the walls. It is our most popular repipe material.
Copper Pinhole Leak Replacement in Mandan, ND
Pinhole leaks in copper usually start as a small green stain or a damp spot on drywall. They are caused by a mix of water chemistry, high velocity and thin Type M pipe, and once they begin they tend to keep appearing. Patching each leak costs $300 to $800 per visit plus drywall repair. We can replace the affected branch or repipe the home with PEX, which does not develop pinholes. We help you weigh the cost of both paths.
Burst Pipe Repair & Replacement in Mandan, ND
Frost goes deep into the ground here, so water and sewer lines must be buried well below the surface to avoid freeze damage. Cold snaps can lead to burst pipes, especially in exposed areas or unheated spaces. When a pipe bursts in your Mandan, ND home, it causes instant water damage and requires urgent attention. Our team provides emergency service to shut off water, remove damaged sections, and replace them with new, more freeze-resistant piping, often PEX, to prevent future occurrences. We work quickly to minimize disruption and water loss.
Water Line Replacement vs. Repair in Mandan, ND
Deciding between pipe repair and full replacement depends on several factors, including the age of your pipes, the extent of the damage, and the frequency of past issues. A small, isolated leak might be repaired, but widespread corrosion or multiple leaks usually warrant replacement. HPN Plumbing provides honest assessments in Mandan, ND, explaining the pros and cons of each option. We help you make an informed decision that offers the most cost-effective and durable solution for your home.

Galvanized Pipe Replacement in Mandan, ND
Many older homes in Mandan, ND still have galvanized steel pipes, which are prone to rust and corrosion on the inside. This leads to reduced water pressure, discolored water, and eventual leaks. HPN Plumbing provides comprehensive galvanized pipe replacement services, removing these failing pipes and installing new, modern materials. Upgrading from galvanized pipes not only improves your water quality and pressure but also protects your home from potential water damage caused by deteriorating plumbing.
