Water Heater Replacement in Irvine
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 precise installation of your new one, connecting gas or electric lines and confirming correct venting and pressure relief valve operation for performance and safety.

Water Line Replacement in Irvine, CA
A leaking main water line can lead to significant 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.
Water Softener Replacement in Irvine, CA
Hard water leads to mineral buildup in pipes and appliances. Around Irvine, flushing the water heater yearly and cleaning aerators keeps mineral buildup from cutting flow and efficiency. If your old water softener is no longer effectively 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 Irvine home.
Pipe Replacement & Whole-Home Repiping in Irvine, CA
Homes in Irvine, CA 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.
Tankless Water Heater Replacement in Irvine, CA
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 Irvine homes. We focus on 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.
Sewer Line Replacement in Irvine
Persistent sewer backups, foul odors or lush spots in your yard can signal a failing sewer line. Earthquakes are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines intact during shaking. We offer complete sewer line replacement using trenchless technology whenever possible, minimizing 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 Irvine plumbing codes, preventing future blockages and costly repairs.
Whole-Home Pipe Replacement in Irvine
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 Irvine, CA
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 correctly sized equipment. Pressure switch settings are adjusted for steady pressure throughout the home.

Frequently Asked Questions About Plumbing Replacement in Irvine
Costs vary by job. A tank water heater replacement usually runs $1,400 to $3,000, a water softener $1,500 to $3,500, a water line $1,800 to $5,500 and a sewer line $4,000 to $15,000 or more.
The timeline depends on the complexity of the job. A water heater replacement typically takes 2 to 4 hours. A major project like a full house repipe or sewer line replacement can take 1 to 5 days. We will provide an estimated timeframe during your consultation.
Climate, freezes and soil type all shape how long plumbing lasts. Intense sun breaks down exposed plastic pipe, sprinkler parts, and outdoor fittings, so they wear out faster than indoor plumbing. Freeze-thaw cycles can damage pipes, and corrosive or shifting soils can speed up pipe degradation. Earthquakes are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines secure during shaking. Our replacement solutions are chosen to withstand these local conditions for lasting durability.
Yes, FKM Plumbing understands that some plumbing failures, like a burst main water line or a severely leaking water heater, are emergencies. We offer emergency plumbing replacement to address critical issues promptly and minimize damage to your Irvine property. Call our emergency line for fast assistance.
Equipment comes with manufacturer warranties, often 6 to 12 years for water heaters and longer for some pipe materials. We also warranty our installation labor.
Consider the age of the equipment, the cost of repair compared with replacement and how often it has needed service. We give you both options with pricing so you can decide.
FKM Plumbing stands behind our work with comprehensive warranties on both labor and materials. Specific warranty terms vary by product and service, but we always back your peace of mind with quality guarantees.
Yes, many major plumbing replacement projects, such as water heater replacement, sewer line replacement or whole-home repiping, require permits from the City of Irvine or the relevant municipal authority. FKM Plumbing handles all necessary permitting so your project complies with local building codes and regulations.
