San Fernando Valley Plumbing FAQ

How do I know if I have a slab leak?

Watch for warm spots on tile or concrete floors, the sound of running water when every fixture is off, a water meter that moves with nothing running, sudden DWP bill spikes, and damp baseboards or mildew. Any one of these deserves a same-week leak detection visit — under-slab water erodes soil and can crack the foundation it sits on.

Should I spot-repair a slab leak or re-route overhead?

One isolated leak in an otherwise healthy system is a fair spot-repair candidate ($2,000–$4,500+). But if your home has galvanized or 50-year-old copper in the slab and this is leak number two, an overhead PEX or copper re-route usually costs less over five years than repeated jackhammer visits. Get both options priced before you decide.

How long do galvanized pipes last in the Valley?

Typically 40–60 years, and hard Valley water pushes toward the short end. Most 1940s–60s galvanized systems still in service are on borrowed time — rust-colored water, dropping pressure, and pinhole leaks are the retirement notice. A repipe with copper or PEX is the permanent fix.

Tank or tankless water heater?

Tanks cost less upfront ($1,800–$3,500 installed) and suit most Valley homes fine. Tankless ($3,500–$6,500) earns its keep in larger households with simultaneous demand and where garage space matters — but it needs adequate gas supply and yearly descaling in hard-water areas. Either way, California requires earthquake strapping and a permit.

Why do my drains keep clogging even after snaking?

Because a cable punches a hole through the blockage while leaving the cause behind — usually ficus or sycamore roots in clay or cast-iron laterals, or bellied pipe sections that collect solids. A camera inspection shows what's actually in there; hydro-jetting or repair fixes it instead of renting you three months of flow.

Is trenchless sewer repair available in the Valley?

Yes, for many laterals — pipe bursting and cured-in-place relining can replace or renew a line without trenching the driveway or mature landscaping. It isn't universal: collapsed sections, severe bellies, and bad slope still need open trench. A camera inspection determines which camp your line falls in.

Do I need a seismic shutoff valve on my gas line?

Los Angeles doesn't mandate them on every existing home, but they're cheap insurance in earthquake country — Northridge taught the Valley that lesson. They're strongly recommended, especially for older homes with rigid black-iron gas piping.

Will a water softener fix my low pressure?

A softener stops new scale from forming; it doesn't remove decades of buildup already choking galvanized lines. If pressure is already gone, the fix is repiping the restricted sections (or the house), with the softener installed alongside to protect the new pipe.

Do plumbers in California need to be licensed?

Yes — a C-36 plumbing contractor license from the CSLB is required for jobs over $1,000 including labor and materials, and only licensed contractors can pull permits. Verify any license number on the CSLB website before signing.

How fast can I get a plumber in the Valley?

For active leaks, sewage backups, and dead water heaters, same-day or next-day service is the norm — call (202) 933-7472. Planned work like repipes and tankless installs typically books within a week or two.
