Is PEX safe for drinking water?

Yes. PEX sold for drinking water is tested and certified for it, and Arizona plumbing code approves it. A lot of the homes built in the Valley in the last 20 years were plumbed with it from day one.

Does PEX hold up in an Arizona attic?

It does when it goes in right. We keep it out of any sunlight, lay it low under the insulation where we can, and keep the connections right at a gas water heater in metal. PEX strung loose across a hot attic floor is how a repipe goes wrong.

Will you leave the old pipes under my slab?

Usually, yes. We cut them off and cap them, and the new lines run overhead. A slab leak cannot happen on a pipe that no longer carries water.

How long does a PEX repipe take?

Most homes take one to three days, depending on size and how many fixtures there are. We give you the schedule before we start, including when the water will be off.

Is PEX cheaper than copper?

In most homes, yes. The pipe costs less and goes in faster. You get an itemized quote for your house before any work starts, and we can price copper next to it if you want to compare.

Can you repipe just part of the house?

Yes. If the trouble is one bathroom or the kitchen line, we can repipe that section. If the pipe is old all through the house, we will say so, because patching one run of galvanized just moves the next leak down the line.

Why most Valley repipes go in with PEX now

PEX is a flexible plastic water pipe. It comes on a roll, so one length can run from the main to a fixture with no joint hidden in the wall. Fewer joints means fewer places to leak.

It bends around corners instead of needing a fitting at every turn. That lets us feed it through the attic and down the walls through small holes. A copper repipe often needs much more of the wall open.

Its inside wall is smooth. Hard water scale has far less to grab onto than it does inside rusted steel.

When PEX is the right pipe for your house

Your home sits on a slab and has a history of leaks under the floor
Galvanized steel still feeds the faucets
Copper has sprung pinhole leaks in more than one spot
You want the job done with as little wall damage as possible
Your budget points away from a full copper repipe

Copper still earns its place in some spots, like a run that has to sit out in the open. We install both, and we will tell you where each one belongs in your house.

How a PEX repipe goes in a slab home

Most Valley homes sit on a concrete slab, with the old water lines buried under it. A PEX repipe usually leaves those lines in the ground and runs new ones overhead.

Map the house

We find every fixture, the main shutoff, and the water heater. Then we plan the shortest runs through the attic and down the walls.

Run the new lines overhead

The PEX goes across the attic, laid low and tucked under the insulation where it can be, then drops inside the walls to each fixture. The old lines under the slab get cut off and capped.

Tie in every fixture

Each sink, toilet, tub, and hose bib gets connected to the new line. Shutoff valves that have seized from years of hard water get replaced while the wall is open.

Pressure test, then patch

We pressure-test the whole system before any wall closes. Then the access holes get patched and the house gets cleaned up.

PEX or copper: the honest trade-offs

Both are sound, code-approved pipe in Arizona. They are good at different things.

PEX costs less to put in: The pipe costs less, and far fewer fittings means fewer labor hours. For most homeowners that is the deciding reason.
PEX forgives a freeze: It can stretch when water freezes inside it, where copper tends to split. That matters more in Anthem and the foothills than it does in Mesa.
Copper does not mind heat or sun: PEX can never sit in direct sun, and it needs care in a hot attic. Copper shrugs off both, so exposed runs are where copper still wins.
Neither one rusts like galvanized: Either pipe ends the brown water and the slow choke of rusted steel. The choice is about cost, layout, and how long you plan to stay.
