Yes, FKM Plumbing stands behind the quality of our work. We offer warranties on our septic tank repair services and the parts we install. The full warranty details will be provided at the time of service, giving you peace of mind that your repair is covered.
Many households need pumping every three to five years, depending on tank size and household use. Regular pumping protects the leach field from buildup.
For minor repairs like baffle replacement, a permit may not be required. Major repairs that involve excavation, major pipe replacement or any work on the drain field typically require permits from the local health department or building authority in San Marcos, CA. FKM Plumbing will help you work through the permitting process and make sure all work is compliant.
Most additives are not needed for a healthy system. Regular pumping, water conservation and keeping grease and wipes out of drains do much more.
If your septic tank is overflowing, right away stop all water use in your home to prevent further spillage. Avoid contact with the wastewater and call FKM Plumbing at (213) 871-0701 for emergency service. We will dispatch a technician to assess the situation and begin repairs as soon as possible.
Minor repairs like replacing a tee or pump typically do not. Tank replacement, field replacement or system changes usually require a permit from the local health authority, and we take care of the coordination.
Rules on septic inspections at the time of sale vary by state and by local health department. Most suburban homes in Southern California connect to public sewer, but septic systems are common in rural, canyon, and desert areas. We can help with repairs found during that inspection.
