A pool leak can be a very difficult thing to detect because there are many things that could be responsible. For instance, you could have a tear in the liner, a leak in the hydrostatic valve, a leak in the filter system or around the filters.

 How to Repair a Leaking Pool

 There are two ways you can handle this situation. You can hire a professional to fix the leak or you can do it yourself. There are several things that you can try if you want to figure out the problem by yourself.

 The Do-it-yourself Pool Repair

 The Sharp Corners and Seams

 The leak usually starts from the sharp corners and seams, and you should always begin your search from there. You can also do a visual inspection for moisture and drips around the pool equipment. Any place the drips are found indicates that there is where you need to start your repairs, and leaks around the equipment are an easy fix compared to leaks in the basin or the liner.

 Check the Basin for Pool Leak Detection

If you choose to repair the leaking pool yourself, you only need to follow these simple guidelines. The first thing is to check is the swimming pool basin. The basin is the most important component of the swimming pool and it is normally the place where there is a leak or issue. If the problem is not in the basin, then you can move on to the pool fittings and skimmer faceplates.

To test the basin, you can use a simple dye to test where the leak is located. A dye test is simple and can easily be completed by a non-professional. When the dye is applied, all you have to do is track the colored water and find the leak. You will need dark food coloring for dye and a turkey baster for this project or you can buy products at the swimming pool supply store.

 Get as close as possible to the spot where you think there is a leak. Then you have to squirt the dye in using the turkey baster. When the dye is put in the pool, then you should closely watch where the dye goes. The dye will quickly go through the leak, and if this does not show that there is a leak, you need to check other areas of your pool.

 Check the Hydrostatic Valve

The hydrostatic valve is under the main drain. You can apply the dye mixture near the main drain and see where it goes. This valve is essential to the proper functioning of the pool, as it balances the water in the pool. If this is not the problem, then you can check for air bubbles. If there are air bubbles, then there is a leak in your pool’s return valves.


If you check all of these things and you can still see leaks, it is better to call a professional and get his opinion. A swimming pool tear in the vinyl or underground plumbing can be very difficult to repair and should be done by a professional.
