Q&A

What should I do if I suspect a toilet valve is leaking, a common issue in San Jose?

A leaking toilet valve is a frequent concern for local homeowners and can lead to significant water waste. Our team at AB/JDD is experienced in diagnosing and repairing these issues efficiently. We'll assess the valve, flapper, and fill mechanism to identify the exact cause—often related to worn washers or mineral buildup from our water—and provide a lasting repair. Addressing this promptly helps conserve water and prevents higher utility bills.

Do you offer inspections for older plumbing systems that might be stressed by local drought conditions?

Yes, absolutely. The drought can put stress on pipes, leading to increased risk of leaks or cracks. We recommend a professional plumbing inspection, which includes using tools like sewer CCTV cameras to check the condition of your lines without invasive digging. This proactive service, which we've offered for decades, helps identify vulnerabilities in water pipes and sewer lines before they become major problems, saving you money and water.

Are your technicians licensed to handle both plumbing and HVAC repairs?

Yes. As a full-service company established in 1954, our licensed technicians are qualified to handle your plumbing, heating, and air conditioning needs. Whether it's fixing a garbage disposal, repairing a gas furnace, or installing a tankless water heater, you can rely on our team's broad expertise. We provide a single, trusted source for your home's essential systems, and all our work is guaranteed.
