Slab leak rerouting services in Nevada: taking the line out of the slab

What a reroute is

In a reroute, the failing run is cut off at both ends and left in the slab, capped and abandoned. New line is installed to carry water to the same fixtures by a different path, usually through walls and the attic.

The route is chosen so that it reaches each fixture that the old run served. A kitchen line might come down from the attic through a wall to the sink. A bathroom line might follow a hallway ceiling.

Because the new line is above the floor, it is accessible. A future leak on it is easier to find and reach.

How the work goes

1. The technician confirms the leaking line by isolation and locating.
2. A route is planned, usually along walls and through the attic, to each fixture served.
3. Small openings are cut in walls or ceilings where the line needs to pass.
4. New line is run and connected to the supply and to each fixture.
5. The old run is capped at accessible points.
6. The new line is pressure tested, and the meter is checked.
7. Openings are closed, usually leaving the wall surface ready for texture and paint.

The crew explains the route before starting. You can ask where each opening will be.

When it tends to fit

A reroute is a common answer for repeat leaks, because it moves the line out of the slab altogether. It also suits leaks under kitchen islands, built-in cabinets, large tile areas or floors that would be difficult to match.

It is often chosen for hot-line leaks that recur, because the hot lines see daily heat cycles. Rerouting the hot side only is a frequent plan.

It suits houses with accessible attics and walls, which describes many single-story Las Vegas Valley homes. Repeat slab leaks covers the repeat-leak conversation.

When it may not fit

Two-story houses, houses with limited attic space and townhomes with shared walls make routes harder. The technician may find the route impractical or may need more openings.

If the leaking line serves many fixtures spread through the house, a reroute becomes larger, and the conversation may move toward a repipe. See repiping after slab leaks.

For a first leak in an open area, a spot repair may be a simpler answer. See slab leak spot repair.

What gets opened

Walls and sometimes ceilings, in small patches. The openings are usually a few inches to a foot across, placed where the line passes through. The attic is entered through its access hatch.

The floor stays intact in most cases. That is the main attraction: no concrete, no tile and no matching of flooring.

The openings are closed afterwards, but wall texture, paint and any finish are separate trades. Ask what the crew leaves.

The attic, heat and insulation

In Nevada, attics can be extremely hot in summer. Crews schedule around heat where they can, and may start early. Expect them to plan time in the attic.

Line in the attic is typically insulated, depending on the pipe and the plan. The technician explains what goes in and how it is protected.

Insulation disturbed during the work is restored where practical. If you have specific concerns, mention them before the work.

What happens to the old line

The abandoned run stays under the slab, capped. It is not removed. It no longer carries water, so it is out of the picture, and the leak is no longer a leak.

If the old line is later exposed by other work, it will be seen as capped. Note the reroute for your records.

If you sell the house, mention the reroute. It is a useful part of the plumbing history.

In Nevada homes

Single-story homes with accessible attics are common across the Las Vegas Valley, which makes rerouting a practical option for many of them. In boom-era neighborhoods, it often follows a second leak. See boom-era home slab leaks.

In planned communities and townhomes, access and shared walls may shape the route. HOA and townhome slab leaks covers that.

In northern Nevada slab subdivisions, attics are similar. Homes with crawlspaces use the crawlspace instead.

How the route is planned

Planning is the heart of a reroute, and it happens before any wall is opened. The technician starts with the fixtures the leaking run served and works backwards: which sinks, showers, toilets and appliances lose water when this line is closed? Each one needs a new feed.

Next comes the path. Water lines like short, direct routes with few bends, and crews look for walls that already carry plumbing, closets that stack on each other and attic space above. Where a wall is shared with a neighbor, or where the attic is too low to work in, the plan adapts.

The technician also thinks about the hot and cold pair. Hot and cold lines to the same fixture usually run together, spaced apart, and the new routes follow that habit. Lines are supported so they do not rub, and they are kept clear of electrical cable and sharp edges.

Finally, there is the question of the water heater. If the leaking run came from the heater, the new hot line starts from the same point and leaves by an overhead route, often through the garage wall and attic. You can ask to see the planned route on a sketch before the work starts. A good crew will draw it for you.

The plan can change once walls are open. A hidden obstruction or a bracing member may force a small detour. The crew explains the change as it happens, not afterwards.

Practical details worth settling first

Several details are easy to settle before work starts and awkward afterwards. The first is access to the attic. Make sure the hatch is clear, and tell the crew if it is in a closet or above a built-in. Move stored boxes away from the opening.

The second is timing. Attics in southern Nevada are very hot for much of the year, and crews often start early. If the route passes through bedrooms, agree on hours that suit the household.

The third is walls. Tell the crew about anything fragile or valuable on the walls they will open: mirrors, art, shelving. Small patches mean small movements, but vibration still travels.

The fourth is closing up. Ask whether the wall openings are patched to bare drywall, and whether texture and paint are included. In most cases they are separate. If you have leftover paint, keep it and mention it.

The fifth is the water. During a reroute, the house will be without water for parts of the day. Ask when, and whether the cold side can be restored while the hot side is worked on.

Lastly, ask how the new lines are protected where they run through the attic and how they will be supported. A clear answer is a good sign.

The new line and how it is protected

The new line is installed with the same care as any supply line, and the choices about material and protection are the technician’s to explain. Ask what pipe is going in and why it suits your house.

Lines are supported at intervals so they do not sag or rub. Where they pass through framing, they are fitted so they cannot chafe. Where they cross the attic, they run clear of electrical cable and of the ducts that carry conditioned air.

In an attic that gets very hot, hot lines lose heat on the way to the fixture unless they are insulated, and cold lines can warm up. Insulation helps both, and the technician says what is planned.

Connections are accessible. That is one of the practical benefits of a reroute: a joint in an attic can be inspected, and a repair, if one is ever needed, does not involve concrete.

Ask for a note of the route, even a rough sketch. It tells the next owner, or the next technician, where the lines go.

And ask where the shutoffs are. Some reroutes add valves that make later work easier, and you should know where they are.

Where this comes up in Nevada

Single-story homes with accessible attics are common in the valley and in many smaller towns. Local pages that cover the homes and conditions around this topic include Henderson, Enterprise, North Las Vegas and Pahrump.

The pages say how common accessible attics are in each place. See the areas page for others.
