HPN Plumbing sees how fast hard water, heat and shifting soil can wear out plumbing. Water in North Dakota is often very hard, with high mineral and sulfate content that builds scale in water heaters and fixtures. Water heaters scale up, softeners lose resin, well pumps burn out and old pipes corrode. We replace these components with quality equipment sized for your home and explain the expected lifespan of each.
Our expertise includes:
- Water heater and tankless unit replacements

Water Heater Replacement in Mandan
When your water heater is leaking, not heating or providing too little hot water, it is often more economical to replace it than to repair it, especially if it is over 10 years old. We install standard tank water heaters, sized properly for your home's needs and compliant with current energy efficiency standards. Our team handles the safe removal of your old unit and the careful installation of your new one, connecting gas or electric lines and confirming correct venting and pressure relief valve operation for performance and safety.

Pipe Replacement & Whole-Home Repiping in Mandan, ND
Homes in Mandan, ND with older galvanized steel or polybutylene pipes often deal with low water pressure, discolored water or frequent leaks. A whole-home repipe with new PEX or copper piping can dramatically improve water quality and pressure and eliminate leak concerns. We carefully plan and complete repiping projects, minimizing disruption and making sure all new pipes are properly routed, insulated and connected, providing a durable and efficient plumbing system for decades to come.
Repair vs Replacement Cost Comparison in Mandan, ND
A common rule of thumb is to replace when a repair costs more than half the price of new equipment or when the item is near the end of its expected life. Replacement also makes sense when repeated repairs are adding up. We give you side-by-side pricing for repair and replacement so you can decide with real numbers. Many replacements also improve efficiency and lower future repair costs.
Sewer Line Replacement in Mandan
Persistent sewer backups, foul odors or lush spots in your yard can signal a failing sewer line. Basements are standard in most homes, and many rely on sump pumps to manage groundwater during wet springs. We offer comprehensive sewer line replacement using trenchless technology whenever possible, limiting disruption to your landscaping. For more severe damage, traditional excavation is performed with careful attention. We make sure new lines are properly graded, connected and compliant with local Mandan plumbing codes, preventing future blockages and costly repairs.
Tankless Water Heater Replacement in Mandan, ND
Upgrade to endless hot water with a tankless water heater replacement. These units heat water on demand, saving energy and space, which is a great benefit for Mandan homes. We specialize in replacing older tankless units or converting from traditional tank heaters to high-efficiency tankless models from brands like Rinnai and Noritz. Our service includes assessing your home's gas line capacity or electrical service, confirming proper venting and precise installation to maximize efficiency and longevity.
Well Pressure Tank Replacement in Mandan
If your well pump is cycling too often or you have inconsistent water pressure, your pressure tank might need replacing. HPN Plumbing installs new well pressure tanks, so your well system operates efficiently and your well pump lasts longer. We correctly size the tank to your system in Mandan, optimizing water delivery and energy usage.
Pipe Replacement and Repiping in Mandan
Corroded, leaking or galvanized pipes can contaminate your water and cause costly damage. HPN Plumbing offers full pipe replacement, or repiping, for homes in Mandan.

Frequently Asked Questions About Plumbing Replacement in Mandan
The cost of plumbing replacement in Mandan, ND varies widely based on the specific service. A water heater replacement might range from $1,200 to $3,500, while a full house repipe could be $4,000 to $15,000+. We provide clear, upfront pricing after a thorough on-site evaluation.
HPN Plumbing stands behind our work with solid warranties on both labor and materials. Specific warranty terms vary by product and service, but we always back your peace of mind with real guarantees.
Many sewer line replacements take one to three days depending on length, depth and method. Trenchless options can speed up the timeline.
Replacing old pipes with PEX or copper offers many benefits. PEX is flexible, corrosion-resistant and less prone to bursting in freezes, while copper is durable and long-lasting. Both improve water quality, eliminate leaks from old pipes and can significantly boost water pressure and flow throughout your Mandan home.
We install water heaters from Bradford White, Rheem and A.O. Smith, tankless units from Rinnai and Navien, and quality softeners and well pumps from trusted manufacturers.
HPN Plumbing stands behind our plumbing replacement services with solid warranties covering both parts and labor. The warranty period varies by the type of replacement and the manufacturer's warranty on components, but we always give you clear information on your coverage for peace of mind.
Key signs include frequent, recurring leaks in the same area, discolored water, very low water pressure throughout the house, heavy corrosion visible on pipes or a major component like a water heater being over 10 to 15 years old and failing. If repair costs approach the cost of replacement, replacement is often the better long-term investment.
We primarily use PEX (cross-linked polyethylene) and copper piping for water supply lines. For sewer and drain lines, we use durable PVC (polyvinyl chloride) or ABS (acrylonitrile butadiene styrene) pipes, based on the application and local codes.
