Water Quality Solutions
Old pipes cause leaks, low pressure, rusty water, and surprise slab issues. We repipe water lines (Type L copper or PEX-A) and replace failing drain lines (ABS/cast iron)—permitted, tested, and inspected to California Plumbing Code. Same-day options in many LA neighborhoods, $75 diagnostic credited toward the work, clean finishes. Call (818) 941-6741 or book online.
Old or damaged pipes can cause leaks, bad water quality, and drainage problems. That’s why we offer professional home repiping services for both drain lines and water lines. Whether it’s a small section or a full house repiping project, our licensed team makes the process easy, fast, and clean.
If your drains are slow, clogged, or backing up often, we replace the old pipes with new ones. Our drain line repiping helps prevent future problems and keeps everything flowing properly.
We replace old, leaking, or damaged water lines to improve water flow and pressure. Our team handles everything from minor repairs to full water-main repiping.
If your entire plumbing system is outdated or worn out, we offer complete whole-house repiping using modern materials that last longer and work better.
We offer both copper repiping options for strength and durability, and PEX repiping solutions for flexibility and cost savings—based on your needs and budget.
Whole-home water repipes: Type L copper or PEX-A with expansion fittings—materials approved under the California Plumbing Code.
Main service upgrades from meter, manifolds, isolation valves, and new hose bibbs
Pressure regulation: if static pressure is >80 psi, code requires a PRV; closed systems also need a thermal expansion tank. We test and size both.
Cast-iron/galvanized to ABS replacement (per CPC and local amendments)
Stack, branch, and fixture drains, new cleanouts for serviceability
Sewer lateral: trenchless options (pipe bursting/CIPP) when feasible; we handle permits and city coordination.
Old or damaged pipes can cause serious problems in your home. From low water pressure to rusty water or bad smells, these signs shouldn’t be ignored. If your pipes are over 30 years old or you’re dealing with frequent leaks, it might be time to consider repiping to keep your plumbing system safe and reliable.
If you notice any of these problems, it may be time for repiping.
Diagnosis: pressure testing, camera inspection, water quality context (LADWP).
Upfront plan & permits: we pull required LADBS plumbing permits; lateral work in the public right-of-way needs a BOE S-Permit and a bonded sewer contractor.
Material selection: Type L copper or PEX-A for supplies; ABS/PVC per code for DWV where allowed.
Installation in zones to keep water on as much as possible
Code testing & inspection
Water lines: tested to working pressure or 50 psi for ≥15 min (method varies by material/manufacturer).
DWV: 10-ft head water test for ≥15 min (or 5 psi air where permitted—many jurisdictions restrict air on plastic).
Patch & finish, re-light and reset fixtures
LA requires permits for most plumbing alterations; plan-check can apply to larger drainage systems. We handle the paperwork.
Lateral work in the street/public ROW = BOE S-Permit; some cases require CCTV before approval and a Bonded Sewer Contractor.
PRV at >80 psi and expansion tank on closed systems are standard CPC requirements—we verify both during repipes.
LADWP’s annual Drinking Water Quality Report is your source for local water quality context (hardness/scale varies by zone).
Digging outside? We coordinate 811 DigAlert utility locates (required 2 working days before excavation).

Have questions? We’ve got answers. Explore our most commonly asked questions to learn more about our services, process, and what to expect when you work with Hi-Tech Plumbing Services.
Yes—LADBS requires permits for most plumbing alterations. We pull the permit and schedule inspections.
Consider a full repipe if your plumbing is over 50 years old, you see frequent leaks or rusty water, notice low water pressure in Hollywood to Long Beach homes, or have recurring drain clogs due to corrosion.
For a 2,000 sq ft Los Angeles house, expect 2–5 days for water-line and drain-line replacement—shorter if using PEX, longer with copper and hard-to-access areas.
Whole-house repiping runs approximately $10,000–$40,000, varying by material (PEX vs. copper), permit fees, drywall repairs, and neighborhood (e.g., Beverly Hills vs. the Valley).
Yes. You can opt to replace just the water-supply lines (hot and cold) and leave existing drain/sewer pipes if they’re in good condition, reducing labor and permit costs.
PEX is 25%–30% less expensive, faster to install in tight Silver Lake or Downtown lofts, and resists scale and freeze cracking. Copper lasts 50–70 years, handles higher temperatures, and is fire-resistant—ideal for exposed or outdoor applications.
