Sump Pump and Sewage Ejector Pump Installation in Downey
Protecting your Downey home from water damage is crucial, especially in areas prone to heavy rains or with basements. FKM Plumbing installs reliable sump pumps to remove excess water from crawl spaces and basements. For homes with plumbing fixtures below the main sewer line, we also install heavy-duty sewage ejector pumps to safely move wastewater. Proper sizing and placement are key, and we make sure your pump has a dedicated circuit and correct discharge piping for optimal performance.

Sump Pump Installation in Downey, CA
Protecting your basement from flooding is important in Downey, CA, especially during heavy rainfalls. FKM Plumbing provides professional sump pump installation, including primary and battery-backup systems. We evaluate your basement's water intrusion risks, soil conditions, and foundation type to recommend the right pump capacity and discharge setup. Proper pit excavation, check valve installation, and discharge line routing away from your foundation are key steps we manage carefully. Our team ensures your new sump pump is ready to handle any excess water, preventing costly damage.
Electric Tankless Water Heater Installation in Downey, CA
For endless hot water on demand and energy savings, consider an electric tankless water heater installation from FKM Plumbing in Downey, CA. These compact units heat water only as needed, eliminating standby heat loss. While they require significant electrical capacity, our electricians work alongside our plumbers to ensure your home's electrical panel can handle the load. We handle all plumbing connections, ensuring proper flow rates and temperature settings for consistent hot water.
Tankless Water Heater Installation in Downey, CA
Tankless water heaters from Navien, Rinnai and Rheem deliver endless hot water and save space in garages and closets. Gas units usually need a larger gas line and new venting, while electric units often need added amperage. We size the unit by flow rate and incoming water temperature. Hot inland summers push water heaters and outdoor plumbing hard, while coastal salt air can corrode exposed metal fittings. We also install isolation valves for future flushing.
PEX Pipe Installation and Repiping in Downey
PEX is flexible, resistant to scale and a popular choice for repiping older homes with failing copper or galvanized pipe. We install PEX with manifold or home-run layouts for balanced pressure. The material handles hard water well and can reduce noise in the walls. We patch access openings neatly or coordinate with your drywall contractor. A PEX repipe can stop recurring pinhole leaks.
Expansion Tank and Sewage Ejector Installs in Downey, CA
Water heater expansion tanks absorb thermal expansion in closed systems, which protects pipes and relief valves. Homes with a pressure reducing valve often need one. We also install sewage ejector pumps for basements, guest suites and fixtures below the sewer line. These systems include a sealed basin, check valve and proper venting. Both installations protect your home from costly water damage.

Local water and ground conditions put heavy demands on plumbing equipment, so proper installation matters for homes in Downey, CA. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. Earthquakes are a constant consideration in Southern California, and seismic straps and flexible connectors help keep water and gas lines secure during shaking.
