Almost every repipe we do starts the same way: the homeowner has already paid for two or three leak repairs and is trying to work out why it keeps happening in a new spot each time. The answer is usually that nothing is wrong with those particular spots. The whole system is at the same age, in the same water, under the same pressure, and it is simply failing in the order that the weakest sections give out.
Six things push a house from repair territory into repipe territory. First, repeat pinhole leaks — more than two in a couple of years anywhere in the house. Second, brown or rust-tinted water from a tap that has been sitting, which is corrosion coming off the inside wall of galvanized pipe. Third, pressure that collapses the moment someone opens a second fixture, which means the internal diameter of the supply lines has closed up with scale. Fourth, visible corrosion or green-blue staining at fittings. Fifth, water that never gets properly hot at the far end of the house. Sixth, and simplest: the house is on original galvanized steel or polybutylene.
Material and age matter more than anything else here. Galvanized steel was standard in this area through the 1960s and it does not last indefinitely — the zinc coating wears through from the inside and the steel underneath rusts closed. Polybutylene, installed widely into the 1990s, becomes brittle and splits at the fittings. Both are past their service life across most of the San Gabriel Valley housing stock. Copper lasts far longer, but in aggressive water it develops pinholes too.
The economics are usually simpler than people expect. A leak repair inside a wall means locating it, opening the drywall, cutting out and replacing the section, then patching and texturing. Do that three times and you have spent a meaningful fraction of a whole-home repipe — and you still have the same old pipe everywhere else. A repipe replaces every supply line in the house, comes with permits and an inspection, and stops the cycle.
What it actually involves is less disruptive than the word suggests. We map the runs first and route the new lines to make the fewest cuts we can, work through the house section by section so you're rarely without water for a full day, pressure-test everything before it's closed up, get it inspected, then patch and texture the access holes. Most homes are done in two to four days.
