Why Is My Inground Pool Losing Water?  

Is your pool unusually thirsty for water? It isn’t a normal phenomenon and might leave you asking yourself, why is my inground pool losing water? Well, there are a number of possible causes of this. A crack might be one of the problems among many others. This is why today we are going to guide on how to identify and deal with water loss from your inground pool.   

Why Is My Inground Pool Losing Water – Why Do Leaks Occur and Should They Cause Alarm?   

Unlike above ground pools, inground pools are constructed and made to fit the ground. It is normal for the ground to have major or minor shifts due to occurrences such as earthquakes. This causes your pool to develop a crack. This is not the only reason, a pool has a lot of plumbing openings that might also develop some technical problems and leak. The walls might also wear and cause a leak.

Whatever the reason might be, a leaking pool can cost you in monetary terms, pool chemicals, heat, and more. It is a cause of alarm that should get you working to solve as soon as you realize it.

How Do I Know That My Pool Is Losing Water Abnormally?   

It is normal for a pool to lose some water to evaporation during the day and splashes. However, if your pool loses over two inches of water within a week, that is a signal of unusual water loss. It might be a serious leak within your pool that’s causing water to seep out. In case you have this situation, it is good to seek help and repair the cracks before your water bills reach the sky.

To confirm an abnormal inground pool water loss, do this simple experiment. 

  • Have some water, preferably full in a basin 
  • Mark the point of the water in your basin and that of the pool
  • Let the basin sit next to your pool the whole day  
  • After this, check the length of water that has evaporated from your basin and pool
  • If the length of the water lost in the pool is higher than that of your basin, then you have a leak

Now then, how do you find the crack?  

If you confirm that your pool is actually losing water, it is time to find the crack. There are a lot of ways you can identify the point of the crack depending on the nature of your water loss. This is how to identify the point of a crack in your inground pool.   

To What Extent Does Your Water Leak?

My inground pool water leaks continuously.   

If this is the case, then your pool must have the shell or vinyl cracked. The task, however, is finding the exact point. Check the pool carefully for such a crack. If you notice a point where you think it is, you can confirm by using a pH tester reagent. To do this:

  • Turn off the pump so that the water remains still  
  • Apply your pH indicator reagent close to the area you think the crack is  
  • If there is a crack, the pH test reagent which shall be colored by now shall seep through that point. This confirms that you have a crack at that point

You do not have to go for a professional. Most cracks shall happen around connections such as the area around underwater lights or pipe connections. Just find some putty or any other sticking reagent that shall work for your pool. Fill it in the problem area to seal the crack.

Is the Area Around Your Pool Wet?    

In case the soil around your pool becomes wet or muddy, then you might be having a major leak. To find out the origin, turn off your pump and check whether the water continues to accumulate. Check your equipment valves and heater and filters for any problem. Consider calling in a professional pool repair service.

Why Is My Inground Pool Losing Water? Is It a Vinyl Pool?   

Vinyl pools are prone to leaking compared to concrete pools. This is because of the thin layer that vinyl has. Vinyl easily tears around the stairs due to the muck traffic experienced here. Other places to check for leaks on vinyl are the corners, ladder, liner, the sinkhole among others. 

To detect a leak, you shall notice some sand accumulating in that area due to the wash away curse by the leaking water. To repair vinyl leaks, just use vinyl patches to cover the tears. However, if the leak is too big or is from too many areas, it might be time to make a replacement for your vinyl.

What Is the Cost of Leak Repair?   

The cost of leak repair shall largely depend on the type and nature of the leak. Minor leaks can be prepared at zero cost by you as explained above. However, if you have tried and failed to find the leak, or you are experiencing multiple leaks, you shall have to go for a professional service. This usually costs somewhere from $160 to $240 and more. Depending on the complexity of your leaks, you might have to spend more.

Final Thoughts

A leaking pool can cause a lot of trouble, especially when left unattended for a long time after detection. Water from a leaking pool can saturate the soil around your pool causing erosion and major degradation of your pool. 

To avoid such an occurrence, you need to act fast. It is advisable that you check for the leaks before calling in a professional service. If the leaks are minor, take some time to seal the cracks to save on the bucks you could have used for a professional service. 

On the other hand, if you have major leaks or cannot detect the crack(s) yourself, you have to seek professional service soonest possible. So, why is my inground pool losing water? 

We hope you got the answers and a way forward.
