Water Line Questions? We've Got Answers.
-
How to clean sediment from water lines?
Sediment buildup usually comes from the main water line or your home's pipes. Flushing involves shutting off the water supply, opening all faucets, and draining the system completely. For severe sediment issues — especially in older galvanized or corroded lines — a professional inspection can determine if cleaning is enough or if replacement is the better long-term solution.
-
How to find underground water line leaks?
We use specialized leak detection equipment including acoustic sensors and pressure testing to pinpoint leaks without unnecessary digging. Signs of underground leaks include wet spots in your yard, unexplained water bills, low pressure, or the sound of running water when everything is off. Professional leak detection saves time, money, and prevents property damage.
-
How to get air out of water lines?
Air in the lines typically happens after repairs, main shut-offs, or pressure changes. To clear it, turn on the lowest faucet in your home (usually a basement or outdoor spigot) and let it run until water flows smoothly without sputtering. Then move to higher faucets one at a time. If air persists, there may be a leak or valve issue that needs attention.
-
How to detect water lines underground?
Detection methods include electromagnetic locators (for metal pipes), ground-penetrating radar, and acoustic listening devices. We also reference property records and meter locations to map your system. Accurate detection prevents accidental damage during digging and ensures we access the right section of pipe quickly.
-
How deep to bury water lines? How deep are water lines buried?
In the Bay Area, water lines are typically buried 18 to 24 inches deep, depending on local frost line requirements and soil conditions. Deeper burial protects against temperature fluctuations and surface damage. We follow California plumbing codes and local regulations to ensure proper depth and long-term protection.
-
What is water line insurance?
Water line insurance (sometimes called service line coverage) is an optional policy that covers repair or replacement costs if your underground lines fail due to wear, tree roots, or ground shifts. Homeowners insurance typically doesn't cover these lines since they're outside the foundation. If you have older pipes or large trees near your water line, this coverage can provide peace of mind and financial protection.
-
What's included in water line installation cost?
Installation costs vary based on distance, depth, soil conditions, and material choice. A full installation typically includes excavation or trenchless boring, the pipe itself (copper, PEX, or HDPE), fittings and shut off valves, connection to the municipal main, backfill and compaction, and site restoration. We provide detailed estimates so you know exactly what's included before work begins.
-
When should I replace my main water line?
Consider replacement if you're experiencing frequent leaks, discolored or rusty water, persistent low pressure, or if your line is galvanized steel or outdated material. Most water lines last 50+ years, but older homes or those with aggressive soil conditions may need replacement sooner. We offer free inspections to assess your line's condition and recommend the most cost-effective solution.
-
Can you install a new shut off valve?
Yes. We install and repair shut off valves at the property line, inside your home, and at individual fixtures. A working shut off valve is essential for emergencies and routine maintenance. If your valve is stuck, leaking, or inaccessible, we can replace it with a modern ball valve that's easy to operate and built to last.
