How Often Should Pool Water Be Changed?

Taking a dip in your backyard pool has a whole host of benefits, providing you with a place to relax, disconnect from the world, or have fun with friends and family.

To fully make the most of your pool, it’s essential that your pool water’s cleanliness is never compromised. 

The importance of water quality cannot be underestimated, as swimming in dirty pool water can cause illness and may even damage the pool over time.

There may be times when it is necessary to drain your pool and change its water, and in this article the team here at Backyard Paradise Luxury Pools will look at how often pool water should be changed and explain how you can do so.

How often should pool water be changed?

When you should change your water will greatly depend on how much you use your pool. Generally, pool water will need to be replaced every five to seven years. Some people will change their water once a year, while others may wait up to five years, or even longer, to do so.

The pool water change frequency will depend on a number of factors including:

• How often the pool is used
• The climate
• The type of water
• How regularly the pool is maintained

It stands to reason that the more regularly you use your pool, the more often the water will need to be replaced. When you get out of your pool, some water will always make its way out with you, and if this is happening frequently then the water level is likely to drop quicker. 

Signs you need to change your pool water

There are a number of signs that suggest your pool water needs changing. These include:

• If the water level has dropped – If you’ve noticed a significant drop in the water level then it’s probably time to add some new water.
• The water is cloudy and smelly – A cloudy and smelly pool indicates that you have a low level of chlorine that isn’t sanitizing the water as it should be. You should consider changing the water in case it has become contaminated. Remember, when you’ve added your new water, the chlorine level should always be between 1.0 ppm and 3.0 ppm.
• The water is green – This could be a sign of an algae infestation, and while shocking the pool’s water may help to eradicate the microorganism, sometimes draining the pool may be necessary. 
• Unclean water – If the water has become dirty as a result of wind or rain causing dirt or debris to enter the pool, or if a little one or pet has had an accident in it, it is probably best to change the water before swimming in it. 

You may also choose to drain your pool and refill it if it’s set to undergo significant repairs, remodeling, or resurfacing. 

How to change your pool water

If you’re planning to change your pool water, make sure you do it on a mild day when it’s not too hot or too cold. Spring or fall are usually the best seasons for this task.

A submersible pump should be used to remove the water, as using your regular pool pump could damage it. 

Once the water has drained you can refill it using a hose. 

It’s always best to use a professional pool company such as Backyard Paradise Luxury Pools to assist with these tasks to ensure it is performed correctly.
