One call to IRBIS covers every plumbing main line and internal pipe need in your home, from water line installation to a full repipe. No sub-contractors, full San Jose code compliance.
We install fresh main supply lines from the property boundary to the house. New water service pipes upgrade your old galvanized runs, delivering durable copper or PEX at steady pressure.
Old service lines corrode and lose pressure over the years. We handle full or partial water line replacement or a targeted water pipe repair when the damage is contained.
When galvanized pipes rust shut behind your walls, a whole-home repipe is the fix. We swap the old infrastructure for modern PEX so every fixture gets a stable, even flow.
We have the machinery and experience to replace water pipes without digging trenches in your property. We use advanced equipment to tunnel and lay pipe from just two small entry and exit holes
A burst main line floods fast. Our crews answer day or night for severe leaks and floods, with same-day dispatch across San Jose to shut the water down quickly.
A little clarity on ownership saves San Jose homeowners money. San Jose Water Company, or Great Oaks Water in some districts, owns and maintains the water main in the street, plus the meter assembly. The service line from the meter to your house, though, falls entirely on the homeowner. So when pressure drops or rusty water shows up at the tap, the cause usually sits on your side of the meter, not the city supply. IRBIS pulls every permit the City of San Jose requires for private residential pipe work.
Do not wait for a catastrophic basement flood. Watch for these subtle signs of pipe degradation.

San Jose soil moves with the seasons. Wet, then dry, then wet again. That shift pushes on rigid metal lines underground all year long. Older pockets of the city still run original galvanized pipes. Willow Glen. Rose Garden. Alum Rock. On the oldest lots, clay pipe still carries the drain and sewer lines. Galvanized rusts from the inside, year after year, until water volume drops and pinhole leaks open up. We pull the worn pipe and run flexible PEX or solid copper that holds far longer.
Every residential pipe project in San Jose runs the same four steps. No surprises, no guesswork.
Step 1
We find the leak first. Then we read the pressure and check what the pipe is made of.
Step 2
Copper or PEX, laid out side by side. Flat-rate pricing, no parts markup.
Step 3
Certified plumbers swap in the new pipe. Your day barely changes.
Step 4
Before we pack up, we pressure-test the whole line. Zero leaks, strong flow, or we keep working.

Questions & Answers
Quick answers to the questions San Jose homeowners ask most about water pipe installation and replacement. Need more details on your situation? Our team is one call away.
Most residential repipes take one to three days. Home size and pipe access set the pace. A single service line swap often wraps up the same day.
Galvanized pipe? Repeat pinhole leaks? Rusty water? At that point, replacement beats patching the same tired line over and over.
Yes, we can do trenchless water pipe replacement, which won’t require excavation. We can install the water lines laterally from two small holes on either side of your concrete.
Look for a current California license. Flat-rate pricing. Warranties in writing. IRBIS meets all three for water pipe work across San Jose.
Leaks that keep coming back. Pressure that stays low. A pipe older than 1970. Any one of those means it's time to replace the main line. A pressure test tells us whether a repair or replacement fits.
Yes. IRBIS covers San Jose and the wider Santa Clara County, with same-day scheduling for urgent leaks and free estimates on planned upgrades.

Most plumbing problems don’t announce themselves in advance. A water heater that’s quietly filling with sediment, a supply line under the sink that’s slowly degrading, a drain that’s 80 percent blocked but still technically draining — these issues build up over months and years until the day they turn into an emergency call and a water-damaged floor.
July 6, 2026
Most homeowners don’t think about their pipes until something forces the issue — a persistent drop in water pressure, water that runs orange when you first turn on the tap, or leaks that keep appearing in different spots, no matter how many times they’ve been patched.

We prepared this instruction that can help you to understand the common garbage disposal failures and how to troubleshoot them.
