A Whole-House Repipe Takes Days. You Won't Go Days Without Water.

That gap — days of work versus days without water — is where the honest answer lives. Below is what actually happens, what stretches the window, and the one pitch that turns a scheduled few-day job into an open-ended one.

Nobody can hand you an exact day count over the phone, because three things about your house decide it. On our whole-house repiping page these show up as cost drivers; they drive the timeline the same way.

The pattern is straightforward: more fixtures, more floors, and worse access all mean more connections to make and more feet of pipe to run. A small single-story with an accessible attic sits at the short end. A large two-story with vaulted ceilings sits at the long end.

A repipe is not one cut and one connection. New supply lines get run and sized on the trunk-and-branch approach our repiping page walks through, and then every fixture in the house gets individually re-tied — every toilet, every sink, every tub and shower, plus the kitchen and the laundry.

The plumbing code (IPC Chapter 2) even names the cluster: a “bathroom group” is defined as “a group of fixtures consisting of a water closet, lavatory, bathtub or shower.” Read that as a toilet, a sink, and a tub or shower — one bathroom is three separate connections, not one. Count the bathroom groups plus the kitchen and laundry and you can see why the day count moves with the house.

Two things keep that work to days instead of weeks.

We run PEX-A, and it goes in fast. The manufacturer of the PEX-A we install states flexible PEX is “much faster to install compared to rigid copper pipe that requires a fitting with each change in direction.” Copper needs a soldered joint at every turn; PEX bends through the run. Fewer joints, less time.

But the walls don’t close the same hour the last fitting goes in. The plumbing code (IPC §312.5) requires the finished supply system be “tested and proved tight,” held under pressure “for not less than 15 minutes,” before it’s closed up. We pressure-test the entire system before any wall gets patched. That verification is deliberate, and it’s part of why a repipe runs across days rather than an afternoon.

Here’s the part the phone quotes leave out. The water is off during the workday while the crew has the system drained and open. Before the crew leaves for the day, they tie the house back together and bring the water back, so the bathrooms and kitchen work overnight. You brush your teeth, flush, and shower on a normal evening; the next morning the water goes back off and the work continues where it stopped.

That was a slab-leak call, not a repipe — but it’s the same operating rule either way: we don’t leave you without water while the clock runs.

Until we’ve walked your house, the honest answer is a range. We won’t hand you a day count over the phone any more than we’d hand you a dollar figure over the phone — both would be a guess. Once we’ve counted the wet groups, checked the attic, and traced the routing, we give you a window you can plan your week around.

And unlike a burst pipe at 2 a.m., a repipe is planned work. You and the crew pick the days. For the full picture of what a whole-house repipe involves start to finish, including the occupied-house reality, that’s the post to read next.

The same instinct that stretches a few days into “a week in a hotel” stretches the invoice, too. Our cast-iron replacement page makes the point on the money side: one failed section gets priced like a $25,000 whole-house job.

If you want a real window instead of an open-ended one, we’ll come look at your house, map the wet groups and the routing, and give you a hard number of days and a hard number of dollars — after we’ve seen it, not before.
