Tankless Water Heater Replacement in Santa Ana, 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 Santa Ana 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, ensuring proper venting and precise installation to maximize efficiency and longevity.

Water Softener Replacement in Santa Ana, CA
Hard water leads to mineral buildup in pipes and appliances. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. 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 Santa Ana home.
Gas Line Replacement in Santa Ana
Old or damaged gas lines pose a serious safety risk and need immediate attention. If you suspect a gas leak or your gas lines show signs of corrosion or age, our certified plumbers in Santa Ana can perform safe and code-compliant gas line replacement. We use appropriate materials like black steel pipe or corrugated stainless steel tubing (CSST) for secure installations, making sure all connections are leak-tested and meet strict safety regulations for your home's protection.
Water Line Replacement in Santa Ana, CA
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, restoring reliable water flow.
Sewer Line Replacement in Santa Ana
Persistent sewer backups, foul odors or lush spots in your yard can signal a failing sewer line. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. 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 Santa Ana plumbing codes, preventing future blockages and costly repairs.
Well Pressure Tank Replacement in Santa Ana
If your well pump is cycling too frequently or you have inconsistent water pressure, your pressure tank might need replacing. FKM 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 Santa Ana, optimizing water delivery and energy usage.
Whole-Home Pipe Replacement in Santa Ana
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 finished.

Water Heater Replacement in Santa Ana
When your water heater is leaking, not heating or providing too little hot water, it is often more cost-effective 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.

Frequently Asked Questions About Plumbing Replacement in Santa Ana
The cost of plumbing replacement in Santa Ana, CA varies widely depending on the type of service. A water heater replacement can range from $1,200 to $3,500, while a sewer line replacement might be $3,000 to $15,000 or more. Whole-home repiping can cost between $4,000 and $15,000. We provide detailed, clear estimates after an on-site assessment.
The timeline for plumbing replacement depends on the complexity of the job. A water heater replacement usually takes 2 to 4 hours. A main water line or sewer line replacement can take 1 to 3 days. Whole-home repiping projects typically span 3 to 7 days, depending on the size of the house and accessibility.
Frequent leaks, rusty or discolored water, low pressure, recurring backups and equipment over 10 years old are typical signs. We can inspect and give you an honest assessment.
We mainly 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.
Replacing old pipes with PEX or copper offers numerous 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 Santa Ana home.
Climate, freezes and soil type all affect how long plumbing lasts. Intense sun breaks down exposed plastic pipe, sprinkler parts, and exterior fittings, so they wear out faster than indoor plumbing. Freeze-thaw cycles can damage pipes, and corrosive or shifting soils can accelerate pipe degradation. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. Our replacement solutions are chosen to withstand these local conditions for lasting durability.
While small fixes might be possible, major plumbing replacements like water heaters, sewer lines or full repipes are complex and best left to licensed professionals. Improper installation can lead to leaks, code violations, safety hazards and costly damage to your Santa Ana home. It is rarely worth the risk.
Most tank water heater replacements take two to four hours. Code upgrades or relocations can add time.
