Keep Your Pool’s Water Levels Safe With These 4 Pieces Of Advice For Pool Owners

Efficient operation of your pool filter system relies heavily on the water level in your swimming pool, but this fact is often overlooked.

Novice pool owners may not realise it, but if you fail to maintain the ideal swimming pool water level, your skimmer box could be at risk of shutting down.

1. Find Your Pool’s Ideal Water Level

We already have you covered with the best robotic pool cleaner around. But we also have essential pool tips for you too. And a swimming pool water level is one to know all about. Finding the perfect water level is a simple process and can typically be judged from sight alone. You should aim to have your water sitting at the halfway point of your skimmer hatch (which sits on the side of your pool).

It is recommended you have your swimming pool water level between one-third and one-half up the pool skimmer box opening. If the level is higher than that, it may slow or even stop debris from being pulled into the skimmer box through the plate or valve. This means that there will be floating debris left on your pool water surface as a result.

Understanding your pool water dynamics is crucial, especially when facing seasonal changes. As  a swimming pool owner, you need to be very much on top of your water levels during times of unpredictable weather.

2. Always Avoid Low Pool Water Levels

Whether your swimming pool water level falls too low or goes beyond the correct depth, immediate action must be taken.

Is your pool’s water level too low?

Is your swimming pool water level dropping? If it sinks below its optimal depth, you could face severe skimmer box damage. Due to the lack of water, your skimmer will start to draw air into the filter system. As a result, the motor for your pump is at risk of burning out.

Replacing your pool filtration system can be a costly issue, so it’s a good idea to do everything you can to prevent your pool’s water level to dip down this low.

Prevent water loss with consistent monitoring. Consider installing water-saving equipment to maintain optimal levels. Also, pool leaks need to be taken care of promptly as they’ll lead to water level issues.

3. High Water Levels Cause Problems (not as dangerous)

Though not as serious as a low swimming pool water level, a high-water level can still pose a mild threat to your skimmer.

Is your pool’s water level too high?

The higher influx of water can reduce the skimmer’s efficiency, which creates a greater likelihood for maintenance work. A non-functioning skimmer also spells doom for the cleanliness of your pool. When the pool filter is out of action, it’s up to you to manually fish out the debris and foliage from the water.

Managing excess water is vital
After big rains you’ll want to assess your pool water level. Having a good set of pool maintenance strategies on hand will be helpful when you need to adjust water levels. Learning or having the right maintenance tips on-hand will ensure your pool pump and pool equipment always operate efficiently.

4. Keep Safe Swimming Pool Water Levels Year-Round

Between rain and evaporation, your swimming pool water level never really stays the same does it? Though the minute changes caused by outside forces are out of your hands, we can still do things to prevent extreme water-level changes. But it all really boils down to simply keeping an eye on it, and then knowing what to do based on what you see.

Daily Checks

By simply checking your water level on a daily basis you can stay one step ahead of the changing tides of backyard pools. All pool owners need to build some type of routine to check the pool water level at a consistency that makes sense. Knowing about calcium hardness and pool water chemical imbalances will aid in your quest of maintaining a clean and easy to manage backyard swimming pool.

Adding and Removing Water

You’ll rarely have to remove water from a swimming pool, but you may need to top it up from time-to-time.

The effects of a low water level are much more disastrous than that of a high one so keeping your water filled is a vital step in pool upkeep.

Just by using these two methods, you can greatly reduce the risk of a dangerous rise or drop in water level, saving you money and unnecessary headaches.

How Heavy Rains Effect Your Pool

When preparing for hurricanes and heavy downpours, many pool owners make the common mistake of draining their pool – something that often has severe consequences.

Your main concern should be your swimming pool’s water level, and you should prepare the space around your pool to accommodate an overflow.

By removing any garden furniture and disconnecting any electrics, you can drastically reduce the risk posed by rising water levels.

When rainfall is on the way, this is a good time to adjust your pool’s water levels.

Covers help manage levels and ensure your pool skimmer is clear to handle the incoming water amounts and flow changes.

A Pool’s Skimmer Box Water Level Matters

There is endless advice available but when it comes to your swimming pool water level, the solution is simple. Maintain proper pool care and keep up with regular checks for your water levels to remain stable.

It is acceptable for your water level to be anywhere from one third to one half of your skimmer box height. If it is to sink below, or rise above this range, then you should return the water to its optimum level.
