Leak repair

Water leak repair in Phoenix

The leak has an address. What happens next is a decision, and the honest version of that decision has more than one right answer.

Three ways a leak gets fixed

Almost every repair we do is one of three moves. They are not ranked, and the best one is not the biggest one. Which fits depends on where the pipe is, what it is made of, and how many times it has already failed.

Repair it where it failed

Cut out the failed section or fitting, put in new pipe, test it, close up. The smallest opening of the three. It is the whole answer when the cause was mechanical — a rock against a buried line, a nail through a stud, a bad fitting. The trade-off is that it fixes that spot: if the pipe failed because of its age and its surroundings, the rest of the run is the same age in the same ground.

Reroute around it

Abandon the failed run where it lies and put a new line somewhere it can be reached — through a wall, up into the attic, around the driveway instead of under it. The trade-off moves rather than disappears: drywall and paint where the new line drops in, a visible run in a garage, and attic pipe that has to be insulated and protected. It is often the sensible call under a post-tension slab, decorative concrete or a driveway.

Replace the supply lines

For a system that keeps failing rather than one that failed once. More of the house is opened, but once instead of every time. That has its own page: whole-home repiping, which here always means water supply pipe replaced because of leaks.

Worth saying plainly: leak detection and leak repair is all we do. We are not a general plumbing company — no sewer work, no gas lines, no water heaters, no drain cleaning, no fixture or appliance installs. If what you have turns out to be one of those, we will tell you that too.

What gets opened up, and what does not

The order matters more than the tools. We locate first, so that when something is opened, it is opened in one place for a reason rather than in three places on a hunch.

Indoors, there is nowhere to hide the pipe

Valley homes are built on slab, so there is no basement and usually no crawlspace to work from. Supply lines run in or under the concrete, or overhead. That is why an indoor repair is nearly always a choice between going through the floor and going around it.

Caliche does not care how urgent it is

Under much of the Valley sits caliche, a cemented hardpan layer. It digs slowly, and it sends water sideways: a leak on a buried line can run along the hard layer and surface well away from the failure, which is exactly why the wet patch is not the location.

Putting it back

We backfill, compact and clean up, and we do not pretend a patch is invisible. Decorative rock goes back and pavers come up and go down again, but tile, plaster and stamped concrete have weathered in Arizona sun, and new material beside old will show. You hear that before the work starts, not after.

Locating comes first, so that anything opened is opened in one place for a reason.

What actually decides it

Four things do most of the deciding, and none of them is a preference of ours.

  • Where the pipe sits. A line under a driveway, a pool deck or a post-tension slab pushes hard towards a reroute. A line in open ground does not.
  • What it is made of, and when it went in. Different materials and eras fail in different places, which changes whether one repair is likely to be the last one.
  • How many times it has leaked. A first failure is an event. A third failure on the same vintage of pipe is a pattern, and patching a pattern is buying time.
  • What is on top of it. Finishes you cannot replace are a real constraint, and a legitimate reason to choose the route that leaves them alone.

Age is not an opinion, it is published

How a neighbourhood was built tells us what is likely under it. In Sun City, 88 percent of homes were built before 1980 and the median home dates to 1973. Around Encanto and Willo the pre-1980 share is 75 percent, and in Maryvale it is 62 percent. In Buckeye the picture reverses: 89 percent of homes have gone up since 2000. That is the difference between a repair conversation and a replacement conversation, and it is why we ask the age of the house first.

The parts that are yours to decide

We tell you what we found, what each option opens up and what it leaves behind. These calls are yours:

  • how much disruption now against how much risk later;
  • whether a finish you cannot match is worth routing around;
  • whether to address the rest of the system while a wall is already open;
  • whether this is going to an insurance file, in which case we photograph and write it up before anything is repaired — see documenting a claim.

Questions we get every week

Straight answers

Do you repair what you find, or hand it off?

Most leaks we locate, we also repair — pool and spa, irrigation, slab, buried supply lines and water mains. If what turns up is outside leak work, such as a sewer line, a gas line or a water heater, we say so plainly instead of selling you something we do not do.

Is a spot repair just a temporary fix?

Not automatically. When the cause was mechanical — something struck it, something rubbed it, a fitting was wrong — repairing that spot fixes the problem. When the cause is the age and condition of the pipe itself, a spot repair is honest but limited, because the rest of the run has seen the same conditions. We will tell you which of the two we think you have.

The wet spot dried up. Is the leak gone?

Probably not. Leaks come and go with pressure and with how much water the household is using, and a leak into caliche can stop showing at the surface while it carries on underneath. The meter settles it: with everything in the house turned off, a dial that is still moving means water is still going somewhere.

A photo of the wet patch, the meter or the equipment pad tells us more in a second than a paragraph does, and it goes to the person who will do the work.

Rather write it down?

A name, a number and a line about what the water is doing is plenty.
