What should I do if I have a burst pipe?

Shut off your main water valve immediately to minimize damage and call an emergency plumber. Turn off electrical appliances near the leak, open faucets to drain water, and our team will arrive quickly to make emergency repairs and water mitigation recommendations.

How do I know if my sewer line needs repair or replacement?

Signs include recurring backups, slow drains across multiple fixtures, foul odors in the yard, or sinkholes. We perform video camera inspections to assess pipe condition and recommend repair, relining or replacement based on the footage.

Are your plumbers licensed and insured in California?

Yes. Cardinal Plumbing Solutions employs licensed, insured plumbers who comply with California and San Marcos, CA local codes. We provide proof of licensing and insurance upon request and stand behind our workmanship.

Do you offer water heater services for tankless systems?

Absolutely. We install, repair and maintain both tankless and conventional water heaters. From sizing and energy-efficient upgrades to pressure relief valve checks and thermostat calibration, we ensure reliable hot water year-round.

How often should I have my drains cleaned?

For most homes, annual drain cleaning prevents buildup and reduces the risk of clogs. Homes with older pipes, large families, or heavy grease use may benefit from bi-annual maintenance to keep drains flowing smoothly.

Can you detect leaks behind walls or under slabs?

Yes — we use non-invasive electronic leak detection and infrared technology to pinpoint leaks behind walls, under floors and beneath slabs. Early detection reduces repair costs and prevents mold and structural damage.

Do you provide commercial plumbing services?

Yes. We serve local businesses, property managers and HOAs with commercial plumbing, tenant improvement plumbing, backflow prevention, grease trap service and emergency response. Contact us for a tailored service plan and fast, reliable repairs.
