Question Answers
What are the signs that my Pasadena home might have earthquake-related pipe damage?
Subtle signs include new, persistent leaks, low water pressure, or unusual noises from pipes after seismic activity. In our area, older pipe connections are particularly vulnerable. We recommend a thorough plumbing inspection if you notice these issues, as we can assess for hidden damage and perform precise repairs to prevent more extensive problems.
Do you handle full sewer line replacements, and what methods do you use?
Yes, we specialize in sewer installation and replacement. For minimal disruption, we often use trenchless pipe bursting—a method that replaces old lines by pulling a new pipe through the existing one, avoiding major excavation. This is ideal for Pasadena properties where preserving landscaping and hardscaping is a priority.
My water pressure seems low. What could be the cause, and how do you diagnose it?
Low pressure can stem from several issues common in our area, including mineral buildup from hard water, a failing pressure regulator, or leaks in the water main. We start with a comprehensive plumbing inspection to check for leaks, test pressure at various points, and examine fixtures. This allows us to pinpoint the exact cause, whether it's a simple faucet aerator clog or a more significant pipe repair.
