Frequently Asked Questions
What should I do if I have a leaking toilet valve or a burst laundry hose in my Los Alamitos home?
For a leaking toilet valve, first shut off the water at the fixture to prevent water damage. For a burst laundry hose, immediately turn off the main water supply to your home. These are common local issues we handle. Our team at SJ Plumbing can quickly diagnose the problem, whether it's a simple washer replacement, a valve rebuild, or a full hose installation. We keep common repair parts on our trucks for faster service, and our focus is on providing a lasting fix that adheres to local plumbing codes to prevent a recurrence.
How does SJ Plumbing approach a major project like whole-house repiping?
As a second-generation plumber, owner John has specialized in repiping since his early days working with his father. We begin with a thorough inspection, often using camera technology to assess your existing pipes. For minimal disruption, we can often use trenchless methods. Our team plans the project around your schedule, uses durable materials that meet Orange County standards, and ensures all new plumbing is pressure-tested and inspected. We handle everything from the initial assessment to the final clean-up, providing a reliable water system for your home.
Do you offer camera inspections for sewer line problems?
Yes, we do. Plumbing camera inspections are a core part of our diagnostic services. If you're experiencing slow drains, backups, or suspect a sewer line issue, we can insert a high-resolution camera into your line. This allows us to pinpoint the exact location and cause of the problem—such as a break, blockage, or root intrusion—without unnecessary digging. Based on what we see, we can then recommend the most effective solution, whether it's hydro jetting, a trenchless repair, or a traditional excavation, saving you time and money.
