Normally, the amount of water in your pool will be lost by evaporation, splashed out and used to supply the filter backwashing process. However, if you regularly add more than two inches of water to your pool each week, chances are your pool has a leak. Is this correct? You don’t need to be in a hurry. Before calling your local pool technician, it’s a good idea to do a preliminary inspection of your pool and determine if you can fix the problem yourself.
Steps
Locate the leak
- Are there any leaks in the device gasket? Look closely at the filter, pump, heater, and plumbing valve.
- Is there a wet area around the pool? Check ground moisture. Take a tour around the pool and facilities. Check for wet soil and areas that are sunken or eroded.
- Does your swimming pool have vinyl liner? Look for tears or cleavage around fittings, surface water collectors, return water eyes, cleaning tools, pool lights, as well as steps and nooks and crannies.
- Mark the pool water level at the surface water collector. Use a piece of tape or a wax pencil to mark the ink. Check the mark again 24 hours later. The water in the swimming pool should not be lost more than ¼ cm per day. On the contrary, it is very likely that your swimming pool is leaking.

- Place a bucket full of water on the pond platform (add something heavy like rocks or bricks to the bucket). Mark the water level both inside and outside the bucket. Make sure the water level inside and outside the bucket is equal. Check the mark again 24 hours later. If the water level outside the bucket drops sharply, your pool is leaking. This test should be carried out when the pump is switched on, and then again when the pump is switched off.

- If water stops at the bottom of the top of the surface water collector, a leak may appear in the surface water collector or filtration system (including pipes). If you suspect a filter system leak:
- First, you should check to see if while the pool pump is working, air bubbles in the water in the water return eye appear or not. If present, the leak is located directly on the suction side of the filter system.
- Make sure the pump gabion cap is tightened and the lubricated waterproof seal is in good condition.
- If the water stops right where the pool lights are, chances are the light housing has leaked.
- If the water drops below the pool light location, a leak may appear in the drain hose at the bottom of the pool.
- If the pool loses more water while the pump is still running, the leak is in the water return eye of the system. In this case, you should check the flow at the sewage system or backwash.
- If you suspect a leak in a surface water collector, pool light, or pad, look closely for signs such as cracks, crevices, or tears.
Fix the leak
- Leaks in surface water collectors: separation between plastic surface water collectors and concrete pools is the most common leak. In this case, you can easily fix it with pool grout.
- Leaks in pool lights: Often the pipeline will be separated, cracked or separated from the wall niche. This case is quite difficult to patch. There are different methods to reconnect a broken pipe connection. You can use two parts cured epoxy resin, with grout, silicone or putty material to overcome this problem.
- Leak in the lining: The simple way is to use vinyl patch to fix. You can use a wet patch if the leak is directly under the water.
- Compressed air is commonly used to pressurize pipelines. The air will move the water in the pipe to the location of the leak, at which point bubbles escaping from the opening will signal the problem area. On the other hand, when a pipe cannot maintain a constant gas pressure, it means that a leak is present there.
- In addition, a dedicated television camera is placed around the pipe to detect leaks. The pool technician will pump air into the pipe, then they will listen to the sound waves coming out with a super sensitive microphone.
- The cost of high-tech leak detection ranges from $150 to $1,250 depending on the location and complexity of the problem. You will have to pay an additional repair fee.
- In addition to the conduits of a closed system, there are several aspects that support the conduit system that does not operate in a closed (pressurized) system. Most pools use an open system (self-flowing, non-pressurized feed) and a frequency equalizer that helps the pool pump maintain its performance during periods of low water levels.
- Frequency equalizers are often forgotten or overlooked in the repair process because replacing the path is an expensive and time-consuming task. The frequency equalizer will connect to the bottom of the surface water collector and the rest to the main pipe, or to a pool wall port close to the location of the surface water collector. This is the little-noticed pipe leading from the bottom of the surface water collector to the main pipe. Since this is a non-pressurized line, there is usually less leakage than a pressurized line, however, it has a longer average life than the rest of the plumbing system, and is a candidate for unexplained dehydration.
- The cause of water loss is often in the plumbing system with a variety of reasons ranging from pipe material, installation quality, age, configuration and soil characteristics. Before you start repairing your plumbing, it’s important to isolate the leak site in the first place to determine if the leak is in the plumbing, or in the structure of the pool.
Advice
- To protect yourself and your family from fraud, if the company you contact is a local contractor, you should ask if they are licensed and insured.
