10 Common Pool Problems and How to Avoid Them

Swimming pools are enjoyable and soothing, as well as a cool place to be in the summer. Maintaining a swimming pool is a whole different story. It can take a lot of time and effort to keep your pool swim-ready. Every pool is special, and you should be aware of the factors that may increase your chances of developing pool water issues.


Here are ten of the most common concrete pool issues—and how to prevent them.

1. Green Algae 

This is the most common form, but it's also the most straightforward to eliminate. It can be seen floating around freely in your pool, producing a distinct green color in the water. This typically happens after a period of time when adequate cleaning and repairs have been ignored. It's past time to service your pool if it's turning green. When it comes to swimming pools, algae is popular, but it can be avoided. Certain chemicals may be used to prevent growth. Regular cleaning is also essential to maintain a clean appearance. It's time to give your pool a good shock  by giving it chlorine. A pH level of 7.2 to 7.6 is considered natural. To prevent algae growth in your pool, aim for these numbers. Once your pool has been shocked, use a pool brush to scrub any residual algae. The filter can take care of the rest.


2. Scaling

Scaling—calcium or other mineral buildup/deposits—can be caused by improper pH, alkalinity, or calcium levels. Etching and calcium nodules, which may appear as drips or mounds, are examples of this. Brush the pool walls periodically to prevent scaling, dilute acid before applying it to the water, only apply salt after 30 days of plastering, and do not allow salt to solidify on fresh plaster.


3. Spalling

A spall is a thin layer of plaster (1/8 inch or less) that flakes or peels off from the bottom side of the plaster base. This is triggered by over-troweling the surface, troweling at an inopportune moment, or troweling with too much water. The spalled area would need to be sanded or re-plastered if it is a wide area.


4. Plumbing leaks

To repair a plumbing leak in a concrete pool, you must first cut out the area where the water leaks under the pool, which may be concrete or the patio. Pressure checking the plumbing and ensuring that it is safely installed are two ways to avoid leaks. However, if the pool or patio changes, a leak may occur.


5. Stained View

A stained pool is almost always a dirty pool. Do you ever have stains in your pool after you've washed it? Then it's likely that it's something else. A stained pool may be caused by rust from a base crack. It may also be due to an overabundance of metal in the pool. Examine the interior and exterior of your pool to determine the source.

6. Popping up/floating

With enough water pressure pressing on it, something will float. Concrete pools are the most likely to float of all the pool types. An entire gunite shell can rise and float, but this isn't a common occurrence. A hydrostatic valve may be mounted and maintained to prevent this.


7. Irritation After Swimming

Do you have a burning or irritated feeling in your eyes, mouth, or on your skin? If you experience this after swimming, you might have some issues to fix. Irritability in the eyes, mouth, ears, skin, and other areas may result from an untreated pool. This is caused by a pH imbalance. Chloramines, a mixture of chlorine and ammonia, triggers the irritation that many swimmers experience. Test pH levels once more to ensure they're within the healthy range of 7.2-7.6. This is the highest level of stress our bodies can bear. Anything that is higher or lower than those numbers can result in redness and fire.


8. Craze cracks

Shrinkage causes a craze crack, which is a light surface crack. While there is no water leakage, excessive crazing may cause additional issues (such as staining, algae, and calcium nodules) and may require replastering.


9. Scratchy Surface

Have you ever come out of the water and found that your toes were red and swollen? Swimming on a scratchy pool surface is bad for the swimmer's feet and bathing suit. It's possible that the scratchy surface is due to who built your pool and what material they used. However, the likelihood of it being caused by calcium build-up is greater. The same pH test as before is used to determine this.


10. Structural cracks

In contrast to a simple surface crack, a structural crack occurs when the concrete pool shell itself fractures. The most common cause of this issue is bad design or construction. The pool must be correctly designed to withstand fragile or expansive soil, and then constructed according to the specifications. Concrete pools may fail structurally and leak water if the design is improperly designed or the pool is not constructed according to the design.
