Whole-Home Pipe Replacement in Hattiesburg
Homes with multiple pinhole leaks, galvanized pipe or polybutylene may benefit from a complete repipe. We replace supply lines with PEX or copper, often rerouting through the attic to avoid future slab leaks. Most repipes take two to four days with water restored each evening whenever we can. Drywall openings are patched when the work is complete.

Well Pump and Pressure Tank Replacement in Hattiesburg, MS
Rural properties rely on well pumps to deliver water, and pump failure means no water at all. Common signs include pressure that fluctuates, a pump that cycles rapidly or no water at the tap. We replace submersible and jet pumps and waterlogged pressure tanks with properly sized equipment. Pressure switch settings are adjusted for steady pressure throughout the home.
Tankless Water Heater Replacement in Hattiesburg, MS
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 Hattiesburg 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, ensuring proper venting and precise installation to maximize efficiency and longevity.
Well Pressure Tank Replacement in Hattiesburg
If your well pump is cycling too frequently or you have inconsistent water pressure, your pressure tank might need replacing. DFM 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 Hattiesburg, improving water delivery and energy usage.
Water Line Replacement in Hattiesburg, MS
A leaking main water line can lead to major water loss, high bills and foundation damage, which is a serious concern for homes on slab foundations. Our water line replacement services address issues like corroded pipes, leaks or low water pressure. We locate the leak, excavate the area if necessary and replace the damaged section or the entire line with durable PEX or copper piping. We make sure of a secure, leak-free connection from the meter to your home, bringing back reliable water flow.
Repair vs Replacement Cost Comparison in Hattiesburg, MS
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 clear numbers. Many replacements also improve efficiency and lower future repair costs.
Water Softener Replacement in Hattiesburg, MS
Hard water leads to mineral buildup in pipes and appliances. Much of the water in Mississippi comes from underground aquifers and is fairly soft, though some supplies carry iron or a sulfur smell. If your old water softener is no longer properly removing minerals, or if it is over 15 years old, a replacement will protect your plumbing and improve water quality. We replace all types of water softeners, including salt-based and salt-free systems, sized for your household's water usage and installed correctly on your main water line to provide truly soft water throughout your Hattiesburg home.

Pipe Replacement & Whole-Home Repiping in Hattiesburg, MS
Homes in Hattiesburg, MS with older galvanized steel or polybutylene pipes often experience low water pressure, discolored water or frequent leaks. A whole-home repipe with new PEX or copper piping can greatly 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 many years.
