Perfect Tankless Plumbing, San Jose, CA
For a burst pipe in San Jose, close the main shutoff near the water meter first, then call us any hour; we replace the failed section with new copper or PEX, pressure test the line, and check the pipe on either side, because aging galvanized and pinholed copper rarely fail at only one point.

Emergency & Leaks
What makes a pipe burst here
In San Jose, pipes rarely burst from freezing. They fail from age: galvanized steel rusting through from the inside, copper thinning until a pinhole opens, a supply hose splitting, or a joint pulled apart by high house pressure.
That means a burst is usually a symptom of the whole line's condition. We stop the water, repair the failure and look hard at the pipe we remove.

Timing
How long until the water is back on
When the burst is on reachable pipe, water is usually restored within an hour or two of arrival.
Bursts inside finished walls or under floors take longer, and we isolate the damaged branch so the rest of the house has water while the repair is finished.
Pinhole copper leaks
Pinholes in copper start small, a spray or a steady drip, often in the crawl space or behind a wall. They are caused by water chemistry and age wearing the pipe from inside, and where there is one there are often others nearby. We cut out the section, install new pipe with proper fittings, and inspect the removed piece for thinning. If it is thin, we tell you, because more pinholes on the same line are likely and a planned repipe may cost less than several emergency calls.

Failed galvanized sections
Galvanized steel corrodes from the inside until the wall fails, often at a threaded joint where the pipe is thinnest. When one section bursts, the neighboring threads are usually fragile too. We cut back to sound pipe, transition to copper or PEX with a dielectric or approved fitting, and pressure test. Working carefully matters here, because wrenching on old galvanized can break a second joint that was holding until then. If the removed pipe is heavily scaled inside, we show you, since it is the clearest picture of what the rest of that line looks like.
Supply line blowouts
Braided supply lines to toilets, faucets and washing machines can burst without warning, especially older rubber washer hoses and plastic-core supplies. The damage comes from how much water flows before anyone notices. We replace the failed line and the others of the same age in the house, check that the stop valves close fully, and recommend braided stainless on every appliance and fixture that still has an older connection. A washing machine hose that bursts while the house is empty is one of the most expensive plumbing failures there is, and one of the cheapest to prevent.

Local context
Old galvanized lines behind many San Jose bursts
A large share of the bursts we answer at night are in the older housing of Willow Glen, Rose Garden and Naglee Park, where many houses predate 1950 and still run their original galvanized steel supply lines, now 70 or more years old. In those homes one failed section is rarely the last. The repair visit is also the moment we can show you the inside of the pipe we removed, which says more about the rest of the line than any estimate.
