We were at least the second company to take on this job, so the homeowner was concerned about how we could be sure that all the leaks were found. She was also convinced that the leak was in the return side plumbing.
We started pump on/ pump off test with the Leakalyzer and found that the pool was losing more water with the pump running. This usually tells us to suspect pressure side plumbing.
We had two techs on this job, so one tech began running a pressure test while the other ran a vinyl scan with the LeakTrac 2400. The pressure test on the pressure side plumbing held, but the LeakTrac was getting a stronger than normal signal coming from the skimmer. We did a quick dye check of the skimmer and sure enough the bottom of the skimmer bowl was cracked. The movement of water in the skimmer, or possibly even a slight shift in the suction pipe when the pump was running caused more water loss. This was a rare situation where higher water loss with the pump running wasn’t an indication of a pressure side leak.
We repaired the skimmer bowl with Leakmaster Pool Glue and fiberglass mesh, which provides a permanent repair that will be able to handle the movement of the pool as time goes on. We charged the homeowner an additional fee for this repair. Once the repair was done, a final Leakalyzer test confirmed the now repaired skimmer leak was the only leak.
Remember that pump on/pump off tests only provide suspicions of where the problem is. Further tests are needed for confirmation.
LeakTrac can indicate a leak in the skimmer with higher than normal intensity.
Count on your own observations, diligence and reason more than what other people tell you.
After opening the pool for the summer the customer noticed significant water loss and gave us a call. When we arrived to the job the Leakalyzer reported nearly 6” of water loss per day.
The first two leaks were found right away while we were gathering information. One was clearly visible while we were inspecting a return fitting and the other was found around an equalizer line while we were scanning the pool with a hydrophone. We were able to repair both leaks with Leakmaster Pool Repair Putty.
After the initial leaks were repaired a new Leakalyzer test reported 2.35” of water loss per day. We used dye to find two more leaks – one at another return fitting and one at the tile line.
Once these leaks were repaired the Leakalyzer was still reporting a loss of 1.84” per day. So far we had found and repaired four leaks but were still losing a significant amount of water. We ran a quick pressure test to eliminate the plumbing as the source of the remaining water loss.
Finally a crack in the tile line deeper down in the pool was found and fixed getting us to a no water loss test. Five leaks found, five leaks repaired. Between the multiple Leakalyzer tests, pressure tests, electronic microphone use, extensive dye testing and even diving in freezing spring water this job was more work than most. Once it was all said and done we felt good that we didn’t just solve one of their problems and move along. The property manager was thankful and eager to get us set up as a vendor for all their properties. They even mentioned that we’d done more than other companies had ever done.
Large leaks in concrete pools can be found with a hydrophone, but it may not pick up smaller leaks.
Using the Leakalyzer throughout the job meant we were there longer finding additional leaks, but it saved us from a costly callback.
Extra effort and a job well done gets noticed and helps drive future business.
Did you know that you can crop data in the Leakalyzer reporter program to make your reports clearer and more accurate? While seeing how the graph responds to a variety of environmental factors is helpful most of the time, there may be situations where an otherwise good test goes awry. Say a diver gets in the pool toward the end of a test and causes the water level to rise, but you still want to be able to include the test in a report for the homeowner. To avoid confusion you can remove the affected data from the .TXT file before it uploads into the reporter program. Here’s how it’s done.
Below is a good, clear test but it wasn’t stopped before a diver got in the water at the end of the test to make a repair. You can see the sharp rise and drop toward the end of the test – this is the portion we want to cut out.
The same test in the Leakalyzer reporter program is below. Note that the detail information is inaccurate due to the surge when the diver was in the water.
To create a reporter file without the misleading data at the end you can cut those data points out of the .TXT the Leakalyzer creates to upload the tests. Open the .TXT file, which should look similar to below:
Find the points that correspond with the data you don’t want on the test and simply delete and re-save. The portion below is what was deleted from the test:
Save the new text file and import the updated version into the Leakalyzer Reporter Program. This will produce a much more accurate report of the water loss in the pool. This is what the report looks like after the data was cleaned.
The estimates for inches per day and gallons per day are now more accurate and the graph is more indicative of what was actually happening to the water level of the pool.
Too many leaks and not enough time? Check out this list of time-saving products and tips to help you cruise though leak jobs as efficiently as possible.
1. Avoid callbacks by confirming all leaks have been found and fixed with the Leakalyzer.
Leaks can be deceiving, and even though you may think you’ve found the only leak in the pool there could be other smaller ones still hiding. Avoid having to return to a job site multiple times by running a Leakalyzer test before leaving to confirm the water level is no longer dropping. This ten minute step can save you hours of time!
Dye Testing Cones are a quick way to identify the flow of water in and out of pipes before starting a full pressure test. They can also be used with the Leaklyzer to isolate the shell of the pool or different lines while running tests. While they shouldn’t be a replacement for the definitive information pressure testing can provide, they can quickly help narrow your search area.
3. Spend less time inspecting vinyl liners by pinpointing leaks in minutes with the LeakTrac 2400.
There is no better way to find tiny punctures and tears in vinyl liners than with the LeakTrac 2400. Over the last 25 years, LeakTrac users have saved thousands of hours that they otherwise would have spent diving and dye testing.
4. Make sure to get complete and accurate information from customers before even arriving at the job site.
Asking the right questions of pool owners can save a lot of time during the information gathering step of a leak detection and lead you to to the leak faster. Check out our blog post for a guide to how to have a conversation that will make your actual time on the job more efficient.
5. Choose repair materials that are versatile, convenient, and work fast.
With a cure time of only 5 minutes, Leakmaster Quick Set Putty is a great option for when you have limited time to make a repair, but still want something durable and long-lasting. Also, check out our pre-cut, clear Vinyl Paches that come in a variety of sizes and are the thickest on the market.
The Super Snorkel tankless dive unit makes diving a breeze and eliminates the need for extra stops to refill bulky air tanks. As much as many of us wish it wasn’t, diving is always going to be ultimately unavoidable in performing consistently successful leak detections, so it’s worth it to have a nimble, easy dive setup to make it as pain-free as possible.
The Light Isolating Dome for dye testing is used to quickly determine if there is a leak in the light without diving or removing the light. Dye is ejected just outside of a small hole in the dome and and will be pulled in through the opening if the light is leaking.

Customer reported that the pool was leaking 1-2 inches per day and that a new liner was installed recently. When we arrived, the pool level had already dropped below the skimmers and returns.
We ran a pump on and pump off test with the Leakalyzer and found the pool was losing slightly more water with the pump off. This indicated that we should suspect suction side plumbing. Since the pool water level was already below the skimmers we dove down to check the main drains. A dye test confirmed that the main drain line was drawing dye from both of the two main drains.
We set up our pressure testing equipment to start pinpointing the location of the leak and ran a quick pressure test with water first to confirm that what the dye was showing was accurate. Once we started inducing air and purged all the water from the line we were able to hear a good leak noise in two spots with the Hydrophone (attached to the XLT30H). The first noise was right at one of the main drain bowls and the other was in a corner of the pool. While we had the main drain lines plugged we also ran another Leakalyzer test, which verified the water loss had stopped in the pool so there was no need to run a LeakTrac on the liner or dye test the fittings, skimmers, etc.
In order to determine which noise we were hearing was actually the leak, we slid an inflatable plug 8’ into the line from the main drain bowl and re-pressure tested. The pressure test still failed, so we knew the leak had to be farther than 8’ away from the main drain bowl. With this information we decided that the place we heard noise in the corner of the pool was the leak location. Another confirming factor was that while we were inducing air, there would occasionally be a bubble that came up behind the liner to the surface of the pool. Before leaving we also ran pressure tests on skimmer and returns to verify the rest of the plumbing was good.
Pressure testing helped us identify actual problem when the noise was heard in multiple locations.
Leakalyzer verified that pool shell was leak free, saving us time during the isolation phase.
The customer called us because they noticed the equipment pad was always wet, and the water level was dropping in the pool (estimated at ½” per day). They could not identify where the water was coming from, but thought the heater may be the problem.
On arrival we ran a Leakalyzer test that showed .6” of water loss per day.
As the customer had reported, the equipment pad was very wet but we found that the heater was dry. We then lifted up the pump, which made a leak under the pump visible.
With the pump off, we then ran another Leakalyzer test that still showed .39” per day of loss, which meant that the equipment leak was only producing .21” of loss per day, so there must be an additional leak in the pool. We started examining the shell of the pool by dye testing a few areas where there had been previous repairs, but none of them drew dye. We than ran the LeakTrac 2400 which led us to two leaks in the same corner: one where a patch was leaking again, and a new hole in the liner about 6” away from the other leak. The LeakTrac 2400 could clearly differentiate between the two holes even though they were close together.
After patching the liner leaks we ran another Leakalyzer test with the pump off that showed no water loss, meaning the only leak left was the one in the pump. Not only did the Leakalyzer help us determine that there were multiple leaks in the pool, but it also confirmed that we had found all of the problems before leaving.
Just because you find an obvious leak doesn’t mean you’ve found all of the problems at a pool – the Leakalyzer can help avoid that mistake!
The LeakTrac 2400 can find multiple leaks in a pool, even if they’re close together.
Customer reported that the pool was losing water and had a light leak patched a year ago. It was a smaller pool with no deep end.
Ran a Leakalyzer test upon arrival which showed a water loss of about ½” per day. Since we knew the light was a suspect area, we checked it right away with the Light Tester dome and it drew dye. After jumping in the pool and opening up the light we were able to pinpoint the leak between the light conduit and light niche with dye. At that point, the family showed up wanting to swim since it was a hot day. Since we had already found and fixed a leak we skipped the final Leakalyzer test… of course we got a call back one week later to let us know that the pool was still losing water.
What could have been a quick job turned into a second trip. The second time at the pool we were able to find a liner leak and a skimmer bowl leak with more thorough investigation. We made sure to run our final Leakalyzer test the second time around after fixing the leaks and didn’t get any further call backs. It’s a good reminder that just because you find one leak doesn’t mean you’ve found them all!
Must be thorough in leak detection! Short cuts can lead to more time spent in the long run.
The Leakalyzer is a crucial tool in multiple leak situations.
When scheduling, make sure the customer understands they can’t swim in the pool during the leak detection!
While evaporation rate for your area can be estimated using our Evaporation Index tool, you can eliminate evaporation all together by running a Leakalyzer test with the cover closed. This can be especially helpful in times when evaporation rates are really high in order to avoid confusing readings. If the cover rests on the pool water in any areas it will need to be completely dry, since the water evaporating off of the top of the cover could skew results.
We received a call about a pool that had just had a new liner installed, but was still losing lots of water. The customer suspected the water loss was in the main drain line. When we arrived to the pool the Leakalyzer confirmed the reported water loss.
The main drain lines were plumbed separately up to the equipment, so we put an open plug in each of the main drains to see if they would draw dye. One line did, but the other did not. To confirm, we pressure tested the line that drew dye with water and it failed. In order to pinpoint the exact location of the leak, we then induced air into the line and began to listen with the hydrophone for a leak under the pool, but didn’t hear any significant noises. We then switched to using the Bigfoot microphone with the XLT30H to listen through the concrete around the pool and still didn’t hear anything that indicated the leak location. Only when we started using the XLT30H ground probes in the soil between the pool deck and the equipment were we able to get close enough to the leak to pick up a great noise and find the exact location of the leak.
Thin ground probe rods included with the XLT30H make it possible to get the probe deep into ground to absorb leak sound vibrations.
Turning air pressure off and back on once hearing the leak location confirms the noise is the one we are making.
