Pool Products Direct does offer leak detection services to include pressure testing of the water lines along with looking for liner leaks using our electronic leak detecting equipment. Before we schedule an appointment to come out, there are some tests you can do that may isolate the problem. In leak detection and specifically water line leak detection you will lose water while the pool system is on and unless the leak is in the bottom drain, not much water loss when the system is off. Additionally, a return line leak typically loses water at a rate of 1-6 inches per day versus a suction line leak at a rate of 1/2 - 2 inches a day. These numbers are fairly accurate for a system that runs 24 hours daily.
There could be a leak by means of a crack in the skimmer bottom. We’ve repaired many of these leaks. You could also have a leak at your filtration equipment thus being the cause of the water loss. There are 2-3 equipment related leaks to look for. The most obvious would be a leaking pool pump seal. If there is constant moisture or water in general at the point where the motor meets the pump then you have a seal leak. If your filter valve has a backwash line then the leak could be caused from a bad filter valve which will often allow the water to escape out the backwash line even when the valve is in the filter mode. If you backwash line is buried it makes it a little more difficult to see if this is the problem. Please check these items first.
Moving Forward - We want you to perform the following tests. Even if you have done a portion of the test we need you to follow these instructions so that we can get real good numbers from these tests.
Fill the pool to the arrows on the skimmer faceplate and place your solar cover on the pool surface.
Shut the pool pump system off for exactly 24 hours.
After 24 hours take a ruler or tape measure and measure the "exact" water loss. Write this measurement on a piece of paper.
Fill the pool with water back up to the same start point which is the skimmer plate arrows. Keep the solar cover on the pool.
Run the pool system for exactly 24 hours.
After 24 hours take a ruler or tape measure and measure the "exact" water loss. Write the measurements on a piece of paper.
Email us (email@example.com) the two 24 hour test results.
Test 1 - pool off - water loss = _______________
Test 2 - pool on - water loss = _______________
After we receive these test numbers we will let you know what to do next or you can simply click on the “Schedule Leak Detection” below.
FYI: Typically if there is any sort of underground line leak or equipment leak the pool will lose more water in Test 2 versus Test 1.
***All tests need to be performed without rain or the numbers will be skewed.
Before investing time in extensive testing procedures it is important to gather information about the pool's actual water loss. When gathering information, you should first determine if there really is a leak. A “Bucket Test” can be performed to determine how much of the observed water loss is due to evaporation and how much is due to a leak. Other tests such as the “Pump On/Pump Off Test” will provide a useful base of information that will be helpful as you continue the leak detection process.
Using a Dye Tester, put a small amount of dye near suspected leak areas in the structure of the pool to see if the dye is pulled out of the pool. Check skimmers, return fittings, lights, cracks, main drains, and hydrostatic valves. Diving Equipment may be necessary for checking for leaks at the bottom of the pool. Hydrophones (an underwater microphone that attaches to an XLT17 or XLT30 Listening Device) can be used to check areas especially in concrete pools that can't be reached without diving.
Instead of visually inspecting every inch of a leaking vinyl liner use the LeakTrac 2400 to survey the entire liner while you stay the deck. Using proprietary electronic technology the LeakTrac directs you to leaks without diving, without dye, and without draining water.
Regardless of the suspected location of the problem, a pressure test of all plumbing lines should be done to confirm whether the leak is in the plumbing or the structure (shell) of the pool. Using the process of elimination, pressure testing allows you to conclusively isolate which part of the pool is leaking so later location procedures can be efficiently targeted.
We offer Pressure Testing Kits that include a Pressure Tester and Open Stem Plugs as well as an assortment of Closed Plugs all packed in a convenient tote. These kits provide what you will need to quickly and confidently pressure test most residential swimming pools.
If a leaking section of plumbing is identified, add a constant flow of air from a regulated air source into the line. As this air escapes into water saturated soil it will make a distinctive bubbling sound that can be pinpointed through the pool deck or soil with an electronic listening device. In most cases this process will enable the location of hidden underground leaks so that repairs can be made with minimal excavation.
Ultimately, the end goal of a leak detection job is a fixed problem. Depending on the nature of what is found the repair can be as simple as slapping on a patch or as complex as renovating the whole pool.
Generally repairs will fall into several categories requiring increasingly complex processes and expensive supplies:
Simple - these problems are generally handled as part of the detection job with adhesives and sealants that are a necessary part of every leak professionals tool box.
Easily accessible leaks and separations between materials in all types of pools - Adhesives and Sealants
Vinyl liner leaks - Vinyl Patches
Simple cracks and separations in gunite and fiberglass pools - Epoxy Putty
Moderate - these problems generally involve the failure of some element in the pool with the resulting decision of fix or replace. Should fix be the option several options are available that can be administered as part of the detection job.
Fitting Leaks - Fitting Saver Repair System
Seal exposed plumbing - Leakmaster Pool Glue
Replace exposed plumbing sections/fittings - Pipe Repair Fittings, Saws and Cutters
Stabalize and repair skimmer/gunite separation- Skimmer Injection Kit
Extensive - sometimes the repair requires a separate trip to the pool with heavy duty cutting, digging or repair equipment. We provide specialized repair systems that are best utilized in the hands of someone having pool construction and renovation experience.
Underground plumbing leaks - Pipe Repair Fittings, Saws and Cutters
Skimmer or fitting replacement
Seal and stabilize gunite shell cracks - Crack Injection System
Fiberglass Stair leaks - Stair Foam Kit
At Pool Products Direct we have the equipment and skillset to locate and repair your pool leaks. Our pricing is less than the competition to include American Leak Detectors. Additionally, we know swimming pools far better than the mentioned company so our repair options and estimates are on average 25-40% lower in cost.
2018 Leak Detection Rates
Air Pressure Test of all water lines including the bottom drain - $305
Air Pressure Test of all water lines EXCEPT the bottom drain - $235
Pin Point Locating of water line leaks after Air Pressure Test - +$125
In pool (Liner) leak detection using our electronic equipment - $245
Liner Patches - $20 per patch which includes labor/material. More than 5 patches the price reduces to $15 per patch applied.
Complete Leak Detection Service (Air-Pressure test of all water lines & Electronic Detection of interior pool structure) - $499
NOTE: If the water temperature in the pool is colder than 80 degrees we charge a flat rate of $150 if we are required to dive in the pool in order to apply a patch. If the pool water is at least 80 degrees we reduce the dive fee to $75.
NOTE: Liner Patches are extra, dive fee not included in this price, and our “pin pointing” of underground water line leaks fee of will be added to the Complete Service if we are required to use our “pin-pointing” equipment.
