Pool Loses Water When Pump Is Off! (Fixed)

If you are noticing a change in the pool’s water level, it becomes essential to get to the bottom of what’s going on.

This is normal in some situations but you might also start noticing troubling patterns.

One of those issues is going to be when the pool loses water when the pump is off.

If the pool loses water when the pump is off, this can mean there is a leak, water is going into the overflow drain, or evaporation is playing a role. It’s best to inspect the surface including assessing for potential cracks.

If there are no cracks then it might just come down to evaporation or excessive use of the pool. This can cause water to splash out of the pool.

You will want to be careful while assessing the pool if it is losing water. It might not always be something as simple as the pool losing water due to evaporation. It could be a leak.

Reasons Pool Loses Water When The Pump Is Off

1. Leak

You have to start with one of the more troubling reasons a pool loses water when the pump is off.

In general, the water is going to get to the point where it will leak aggressively.

This is a major concern because it shows a compromised pool that is only going to worsen. This includes a potential crack getting larger in the pool to the point it leads to major holes.

You have to be diligent while assessing the pool water level. This is important.

If you are not taking the time to do this, the pool water level is going to drop to the point it becomes difficult to use the pool.

Always stay on top of this and take the time to walk around the pool to see if there is a potential crack. If you find it early on, you will have no trouble taking care of it.

2. Overflow Drain

You will also want to take the time to think about the overflow drain.

The reason for doing this is to make sure the overflow drain is in a safe place. The overflow drain is set up to help control the water level.

If you are noticing the water spilling over then this might be the reason it is losing water.

The overflow drain is doing its job and this is normal.

The best way to consider this as a potential reason is to see what the starting pool water level is. Was the pool water level too high?

If it was then this is the main reason you are dealing with this type of problem. It will get worse if you are not careful.

3. Evaporation

You have to take the time to think about evaporation as a potential reason too.

This is often the most common reason when it is hot outside. The pool is going to be dealing with the heat and sun, which is going to cause water to evaporate much faster than on other days.

Of course, this will also be sped up if there is no pool cover in place.

You have to be focused on what you are doing when it comes to something like this. It’s the best way to feel comfortable with how the pool works.

If it has been hot for the past few days, you might want to wait a bit. Just pay attention to how much water is lost in the pool per day.

4. Constant Use Of The Pool

Have you been using the pool more recently?

This is another reason that pops up in a situation such as this and it is normal for things to get to the point where the pool water level drops.

You should take the time to figure out how the pool is being used and what needs to be done to get it back to normal.

If a lot of water is splashing out, this is going to be the reason things are not working out as you want them to and the pool water is dropping rapidly.

Final Thoughts

it is important to go through this advice when it comes to a pool that loses water when the pump is off.

If the pool loses water when the pump is off, this means there is a leak due to a crack in the wall, water is going into the overflow drain, or you are facing issues with evaporation. To fix this issue, look for potential cracks in the pool.

This is the best way to make sure you have things under control and it does not get to the point where the water does not work as intended.

Look into this to make sure things turn out as you want.
