If you suspect a pool leak in your Phoenix or Scottsdale pool, it's crucial to hire a pool professional with specialized equipment and experience in pool leak detection. At Leak Tech, we specialize in pool leak detection services in both Phoenix and Scottsdale, and we are often asked: "How do you find a pool leak and what does the process involve?" Here’s a quick rundown of what we do to locate and repair pool leaks.
We typically start by pressure testing all accessible plumbing, including skimmer pipes, vacuum lines, and return pipes. To pressure test a pipe, we plug both ends with specialized rubber or pneumatic plugs. These plugs allow us to build up pressure in the pipe, preventing water and air from escaping. At one of the pipe outlets, we use a special open-end plug with a connection for a pressure gauge. Once the plugs are in place, we build up pressure with water and let it sit for a few minutes. If there’s a pressure drop, it means there’s a leak in the pipe. If it holds pressure, the pipe is in good condition, and we move on to the next one.
If a pipe loses pressure during the test, we use an ultrasound listener to locate the exact location of the leak. Ultrasound devices pick up underground noises caused by the leaking pipe.
After completing the pressure test, we proceed to inspect the pool shell for potential leaks. This process involves the use of two key tools: leak testing dye, which is non-toxic, and a hydrophone device. The dye test is an effective method for identifying leaks by applying a small amount of colored dye near areas that appear suspicious.
Typically, we focus on specific locations that are prone to leaks, such as cracks in the plaster, the edges of the skimmer mouth, PVC pipe outlets, and around the pool light fixture. By carefully releasing a controlled amount of dye near these areas, we observe how the dye behaves. If the dye is drawn into a crack, crevice, or joint, it serves as a clear indication that there is a leak present in that area. The suction of the dye into the gap reveals a break in the pool shell or plumbing system that allows water to escape.
The second tool we use is a hydrophone, which is an underwater microphone designed to detect the sounds of escaping water. By listening closely, we can pick up even the faintest noises of water leaking through cracks or pipes, giving us another layer of confirmation in locating the leak.
This combined approach of using DYE TESTING and hydrophone technology allows us to pinpoint leaks with precision. It’s a crucial step in the overall leak detection process, ensuring that no potential issue is overlooked and that we can move forward with targeted repairs, if necessary.
Homeowners often worry about the pressure test damaging their pipes. However, the pressure we use to test pool pipes is only about 25 psi, while PVC schedule 40 pipes are rated to handle up to 160 psi. There’s no need for concern—pool plumbing is designed to withstand much higher pressures than we apply during the test.
Maybe. If we detect a leak using the hydrophone or notice a suspicious area at the bottom of the pool, we may need to dive. Diving in winter can be more challenging, but we use specialized dry suits, weights, and diving compressors to ensure safety and comfort even in cold water.
In some cases, yes. For pool shell leaks, we can apply same-day epoxy patches. These are usually temporary fixes but can stop the leak until a more permanent repair is scheduled. However, underground plumbing leaks are more complex and typically require more time, so we’ll need to schedule a full day for those repairs. Smaller repairs at the equipment area can often be done during the leak detection visit.
Unless the repair involves the bottom of the pool (e.g., a pipe broken under the pool floor or a crack in the shell), there’s usually no need to drain the pool. We can often plug off the leaking pipe on both ends to prevent water from flowing back while we make the repair.
Almost never. However, if your pool has pop-up heads (in-floor cleaning system), we may need to drain the pool if the leak is in a pop-up pipe. Most leaks in pop-up pipes occur under the pool floor, and ultrasonic listeners don’t work underwater, so draining the pool may be necessary in this case.
You don’t have to, but it can be helpful to know exactly how much water your pool is losing before we start. The BUCKET TEST is a great starting point for understanding the severity of the leak and can provide useful information for the leak detection process. If you’re unsure how to do it, you can find instructions on our website.
