Your pool will naturally lose some water to evaporation, some to splash-out and some to backwash wastewater. You will also gain water from rainfall. My rule of thumb is that if you’re routinely adding more than two inches of water to your pool per week, you probably have a leak that is worth spending some time and possibly money to repair.
Pools are meant to be watertight but sealants will deteriorate while other parts of your pool shift and settle or just plain wear out. Pools can leak through any of the fittings or accessories, plumbing, or even right through the shell. It is important to repair leaks, not only to save water, heat, and chemicals, but also to prevent undermining pool structural components and washing away fill dirt that supports the pool walls and pool deck.
Leak detection is a highly specialized branch of the industry. Ninety-five percent of all phone calls I get from worried pool owners about a leak turns out to be inexpensive to repair. So relax, if you can’t take care of the problem yourself a professional will be equipped to do so for you. If you suspect a leak, review the following things before calling for service:
Is Your Swimming Pool Losing Water? All swimming pools are susceptible to leaks, whether old or new, plaster or vinyl. Leaks can be caused by ground movement and settling, aging, even your pets. Fortunately, We have a complete leak detection service to find and repair annoying leaks before further damage can occur to the pool or surrounding area. Call our service department to make an appointment so we can find that leak.
At Poolleaks we specialize in Swimming Pool Leak Detection utilizing the latest technologies. We incorporate video cameras, pressure testing, thermal imagers, microphones to pinpoint leaks in your pool pipes. We use a leaked track 3rd generation scanner to test your pool liners.
We now offer no-dig solutions for most common repairs.
Pressure testing consists of the technician plugging your plumbing lines and inducing water into the plumbing. A pressure gauge on the pressure testing rig will allow the technician to determine if there is a loss in pressure (indicating a leak) in the line or if the pressure holds (indicating no leak at this line). The technician may find that the leak is in the return line or the suction line or both.
*Pin-Pointing the Location of the Leak
Once the technician has determined that a leak exists in the plumbing line, they may use two devices to “pin-point” the general area of the leak so that the repair can be direct and without waste in time and expense.
If the leak is rather large and likely in/under the soil, the technician may induce compressed air into the plumbing line. They will then use an electronic listening device to listen for loud or an unusual bubbling sound. The technician will generally mark this area with tape so that the owner or company performing the repair knows where the leak is located.
If the leak is small or not located in/under the soil, then helium detection may be used by the technician. When detecting these types of pool leaks, the technician will induce helium gas into the plumbing lines. Then they will canvas the pool and equipment area to look for high levels of helium indicating the location of the leak. The tool for this is called a helium detector. Once the area is discovered, the technician will mark such area so that others will know the location of the leak for repair.
*Structural “Static” Tests
If no loss of pressure is found in the swimming pool plumbing, then the technician may decide to move forward with a structural test. This is where the technician will give your swimming pool and use dye to determine if any areas inside the pool are pulling the dye (indicating a leak). The dye used is a special purple or green/yellow dye in a syringe with a very small capillary tube so that a tiny ribbon of dye can be ejected and movement of the dye can be observed.
Common areas that are dye-tested include but are not limited to: lights, returns, skimmers, skimmer throats, vacuum fittings, anchor fittings, tile joints, cold joints, main drains, hydrostats and more.
Once the areas of the leak have been located the technician will inform you of the location of those leaks so that they can be properly repaired.
The structural tests often involve divers that use compressed air to be able to properly perform these tests underwater.
