The service

What pool leak detection is, what a visit covers and where the line is.

The short answer

Pool leak detection is a diagnostic service. Pool Leak Detection in Union City is booked through pros who cover its 1 ZIP codes, in neighborhoods such as Old Alvarado, Decoto, and Alvarado. In Union City, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Each pro sets their own price and warranty, and you choose.

What a pool leak detection visit includes

What is included depends on the jobs you pick and on how each pro sets up their visit and timing. You see the exact scope with each pro's price before you book.

  • Evaporation-versus-leak bucket test
  • Dye test of the shell, fittings, and light niches
  • Plumbing pressure test
  • Equipment and pad leak check
  • Written finding with repair recommendation

What shapes a pool leak detection job

These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.

Is the loss real or evaporation
Sun, wind, splashing and an uncovered surface all lower the water without a leak.
Where the leak could be
Shell cracks, light niches, skimmers, returns, equipment connections and buried plumbing each need different tests.
Pool type and plumbing layout
Plaster, fiberglass and vinyl fail in different ways, and long, hidden or older pipe runs are harder to pressure test.
Equipment used and access
Pros use dye, pressure testing and listening equipment, and each needs access to the plumbing and a calm pool.
Soil, groundwater and ground movement
Wet soil beside the pool can point to a leak or can come from rain and irrigation.
Where in Union City the job is
Union City's mix of older and newer housing means providers see everything from simple repairs to complex system upgrades. The network's range of skills covers every job. Tell the pro your neighborhood or ZIP code so they know the age and style of the home.

What you receive

A leak detection visit ends with findings you can use to decide the next step. Each pro sets what they provide, and the written finding is the main deliverable.

  • The result of the bucket test, with how the pool loss compares with evaporation
  • The results of the dye tests on the shell, fittings and light niches
  • The results of the pressure tests on each plumbing line that was tested
  • A note on the pump, filter, valves and pad for drips or wet ground
  • The likely location of the leak or leaks, or a note that none was found
  • Photos of the tests and any visible damage
  • A repair recommendation and which trade is suited to do the work

What is not part of pool leak detection

Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.

  • Any job where labor and materials together reach $1,000 or more, such as excavating to reach a buried line. A licensed contractor takes that work.
  • Excavation, breaking up decking and replacing buried plumbing. That is licensed contractor work and is planned after the finding.
  • Replastering, relining or crack repair in the shell unless the pro lists it as part of the booking.
  • Repair of a pump, filter, heater or other equipment. That is the pool and spa equipment repair service.
  • A guarantee that every leak will be found. Some leaks are small or hidden and may need another test.
  • Repair of the surrounding yard, drainage or house damage caused by water.

Plan your visit

How booking works, how to get ready, and what to expect where you live.

How booking pool leak detection works

  1. Say what needs doing

    Add your ZIP and a few words about the job.

  2. Compare pros near you

    Each pro sets their own price and warranty. NorTech does not pick for you.

  3. Book the pro you pick

    Add photos and details on their page. Your card is held and only charged after the work and the photos.

  4. Photos and a warranty

    Your pro backs the work with a workmanship warranty — if covered work is not right, your pro makes it right, free.

Before you book pool leak detection

Quick things that save a trip. Tick them off as you go; none of it is required to book.

0/7
Let’s get you readyTap a card when you have done it.

Run your own bucket test first

Fill a bucket, set it on a pool step with the water inside and outside at the same level, and mark both. After a day, compare the two.

Record how much water you add

Write down each time you top up the pool and roughly how much. A record over a week or two shows the rate of loss and whether it changes with the pump on or off.

Look for wet spots and damage

Walk the pool and equipment pad and photograph wet soil, cracks, loose tile, soft decking or sunken pavers. Where the ground changes often points to the leak.

Note whether the loss changes with the pump

If the pool drops only when the pump runs, the leak is likely in the pressure side of the plumbing or equipment. If it drops with the pump off, the shell or suction side is more likely.

Keep the water level normal

Leave the pool at its normal level for the tests. A pool run too low can strain the shell and the pump, and a very different level makes it hard to compare results.

Share the history of the pool

Tell the pro about past leaks, repairs, freezes, and when the loss began. A change after a storm, a plumbing repair or a new piece of equipment is a clue to where to test first.

Say where in Union City you are

Add your neighborhood, for example Old Alvarado, Decoto, and Alvarado, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

How where you live changes pool leak detection

Add your ZIP in the booking card at the top to see weather alerts and the season for your area.

The ground around the pool hides or shows a leak

In clay soil leaking water can stay near the pool, soften the ground and move decking. In sandy or rocky soil it drains away quickly and leaves little sign. Pools on slopes can leak toward the house or a neighbor. Wet patches, sinking pavers, new weeds or green grass near the pool are clues, so mention anything you have seen in the yard.

Fill in the blanks first. The note goes to the pro you choose.
