If you have an in-ground pool, you want to make sure that you have water in it when you want to go swimming. But if you are having to top off your pool frequently, you may have a problem with a leak. There are several ways that you can track down a leak and maybe narrow down to where the leak may be. 

Mark It

One thing that you can do is to mark the water level, and then check back every 24 hours to see if it has dropped, and if so, how much it has dropped. There are several ways that you can mark the water level in your pool. One thing that you can do is to use a grease pencil and just mark a line right where the water level is. If your water level continues to drop, you can mark a new line every 24 hours, which will let you track how much water you are losing, which can let you know the severity of the leak. Another way that you can mark your water level is to use a bit of tape and line it up evenly with the water level. You will want to make sure that the tape will stand up to the water, but won't leave any residue when you take it off. A third way is to get a clear container and fill it with water and set it on a pool step. Add some rocks or bricks until the water level in the container matches that of the pool. It may take some trial and error for you to get this perfect. 

Use Some Color

If you are relatively sure that you have figured out where the leak is, you can use some food coloring or dye to track it down. First, you are going to want to turn off your filter and anything else that might cause the water to move and wait for the water to still. Then you are going to want to put some food coloring or dye in the water. You don't want to use it all, just enough that you have a noticeable amount of color. Watch the puddle of color and see if it moves towards any one area. 

If you have tried everything you can and you still can't find the leak or still aren't sure that you have a leak, it's time to call in professionals, like those at Parkway Pools Inc, and let them figure out what is going on with your pool.
