Pool Leak Detection Near Me Checklist: How to Find and Fix a Leak in Your Pool

Use this pool leak detection checklist to find pool leaks in your inground pool. Diagnose water loss, run a bucket test, and know when to call a pro.

Is your pool losing water? Before you panic, there is a simple way to figure out what is going on. Whether you own an inground pool or a ground pool, this pool leak detection checklist will help you diagnose the problem step by step.

At Leak Detection Manitoba by Aqua-Tech, our leak detection services have helped Ontario pool owners find the leak, fix the damage, and get back to enjoying their swim season. With over 30 years of expertise, our professional team uses advanced diagnostic equipment to pinpoint the exact location of the leak so you do not waste time or money on guesswork.

Use this checklist to determine if your pool is leaking, or if you're losing water due to evaporation. Then you will know exactly when to call our expert service department for help.

Step 1: Check Your Pool's Water Level

The first thing every pool owner should do is check the pool's water level. Here is how:

  • Mark the current water level on the skimmer faceplate or pool wall using a piece of tape.
  • Wait 24 hours without using the pool.
  • Check the pool level the next day.

If the water level has dropped more than a quarter inch in 24 hours, you may have a leak. Normal evaporation in Ontario during summer is about an eighth of an inch per day, so anything beyond that is a sign something else is going on.

Step 2: Run the Bucket Test

The bucket test is the simplest way to confirm whether your pool water loss is due to evaporation or an actual leak. Here is how to do it:

  1. Fill a clean bucket with pool water and place it on the pool step so the water inside the bucket is level with the pool water outside.
  2. Mark the water level in the bucket and the pool level on the outside of the bucket with tape.
  3. Wait 24 hours. Do not swim or run the pump during this time.
  4. Compare both levels. If the pool water dropped more than the level in the bucket, you likely have a leak in your pool.

This simple test helps you determine if much water is being lost from a leak or just from normal evaporation.

Bucket Test Result What It Means Next Step
Pool and bucket levels dropped equally Water loss is due to evaporation. No leak detected. No action needed. Monitor weekly.
Pool dropped more than the bucket Your pool is leaking. Water loss is beyond normal evaporation. Continue this checklist. Call a professional if needed.

Step 3: Inspect the Pool Liner and Shell

Now that the bucket test has given you confirmation that a leak exists, it is time to look for the source of the leak. Start with a visual inspection:

  • Check the vinyl liner. Look for tears, holes, cracks, or areas where the liner has pulled away from the wall or floor. Even a tiny hole in a vinyl liner can cause significant leakage over time.
  • Inspect the skimmer and fittings. The skimmer box and return fittings are two of the most common spots for pool leaks. Look for cracks, gaps, or signs of wet soil around these areas.
  • Look at the deck and surrounding area. Wet spots, soft soil, or mold near the pool deck often point to an underground pipe leak.

If you can see visible damage, you have found a likely source. If not, the leak may be hidden in the plumbing or underground lines.

Step 4: Use Leak Detection Dye to Find the Leak

A leak detection dye test is a simple, affordable way to locate small leaks. You can buy a dye kit or use a syringe with food coloring. Here is how:

  1. Turn off the pump so the pool water is still.
  2. Swim or wade to the area you suspect is leaking.
  3. Slowly release a small amount of dye near the suspected crack, hole, or fitting.
  4. Watch the dye carefully. If it gets pulled toward a specific spot, that is the location of the leak.

This underwater technique works well for finding leaks around the skimmer, return jets, vinyl liner seams, and light fittings. Leak detection dye helps you identify the exact spot before calling in the pros.

Step 5: Check the Pool Equipment and Plumbing

Not every leak happens in the pool itself. Many pool leaks come from the equipment pad or underground plumbing. Check these areas:

  • Pump and filter. Look for drips or wet spots around the pump housing, filter, and pipe connections.
  • Heater and other equipment. Inspect the heater, chlorinator, and any water features like a fountain for signs of leakage.
  • Underground pipe lines. If the ground between the pool and the equipment pad is wet or soft, you may have an underground pipe leak. This type of leak is harder to detect leaks without professional diagnostic equipment.

If you find a leak at the equipment pad, sometimes tightening a fitting or replacing a gasket is all it takes to fix the problem. But if the plumb lines are underground, that is when you need a professional.

Step 6: Run the Pump Test

This step helps you diagnose whether the leak is in the pool shell or in the plumbing lines:

  1. Run the bucket test for 24 hours with the pump on.
  2. Then run the bucket test for another 24 hours with the pump off.
  3. Compare the results.

If the pool loses more water with the pump running, the leak is likely in the return side plumbing. If the pool loses more water with the pump off, the leak may be on the suction side, near the skimmer or drain. If water loss is the same either way, the leak is probably in the pool shell or vinyl liner.

Pump Test Result Likely Leak Location
More water loss with the pump ON Return side plumbing (pressure lines)
More water loss with the pump OFF Suction side plumbing (skimmer or drain lines)
Same water loss either way Pool shell, vinyl liner, or fitting

Step 7: Know When to Call a Professional

You have done the troubleshooting. You have a good idea of where the leak might be. Now it is time to decide: can you fix it yourself, or do you need expert help?

You can handle it yourself if:

  • The leak is a small hole in the vinyl liner that a vinyl patch kit can fix
  • A fitting at the equipment pad just needs tightening
  • The issue turned out to be normal evaporation

Call a professional pool leak detection service if:

  • The bucket test confirms a leak but you cannot find the source
  • You suspect an underground pipe leak
  • The pool keeps losing water even after a DIY repair
  • You want a full diagnostic inspection with advanced equipment
  • The leak is in the pool plumbing and needs skilled repair

Our service department at Leak Detection Manitoba uses advanced equipment to find the source of the leak and pinpoint its exact location, even when the leak is hidden underground or inside the plumbing. We are the Canadian leak detection experts Ontario pool owners trust.

  • Inspect the vinyl liner, skimmer, and fittings for visible damage, cracks, or a hole.
  • Use leak detection dye near suspected spots to find the leak.
  • Check the pump, filter, and equipment pad for drips or wet areas.
  • Run the pump on and pump off test to diagnose plumbing vs. shell leaks.
  • Decide: DIY vinyl patch repair or call a professional for advanced leak detection?

Following this checklist will help you diagnose the issue, find the source, and make the right call on whether to fix it yourself or bring in the experts.

Pool Maintenance Tip: Prevent Leaks Before They Start

The best way to avoid a costly leak repair is regular pool maintenance. Here is our recommendation for Ontario pool owners:

  • Inspect your liner and fittings at the start and end of every swim season.
  • Keep your pool water clean and chemically balanced to prevent liner damage.
  • Do not drain your inground pool without professional advise. Draining can cause the liner to shift and crack.
  • Monitor your pool's water level weekly. If you notice the water level dropping consistently, run the bucket test right away.
  • Schedule a professional inspection once a year to catch problems before they become expensive.
