When Should You Drain Your Swimming Pool

When Should You Drain Your Swimming Pool
Written by Rohan Mathew

Your swimming pool allows you to relax with your friends and family, but if not taken care of, it can also cause problems. Draining a pool can be an expensive task, but there are times it is necessary to do it. Filling up your pool weighs on your water bill, and it is also essential that you know where you are draining your pool before starting the process. You should know when draining your pool is required so you don’t end up wasting water.

Here are the top reasons it becomes necessary to drain your swimming pool.

Dry climate

If you live in drier climes, your pool water will evaporate more, and when the weather is hotter, you will lose more pool water. In this case, you need to fill your pool up more often. When the water level drops and you don’t fill it up, it will cause your pool water to become hard.

The chemical balance of your pool will be affected, which will require you to balance it. If the water level is normal, you don’t need to add more water but instead add more chemicals for safe balance.

If the chemical balance continues to shift, the cheaper option will be to drain the pool and fill it with fresh water.

Regular Heavy Pool Cleaning

The standard practice for caring for a pool will be to completely drain it every five to seven years. If you have been following the practice of cleaning your pool regularly, it will become more challenging to do this with chemicals after many years. After prolonged use, it is recommended that you drain your pool and fill it with fresh water. The chemicals in the water can make it difficult to clean your pool over time. So if you have more people sharing your pool, it will be difficult to get out biological substances like dead skin cells, hair, and body oils—also, other chemical substances from hairsprays, sunscreen, makeup, etc.

Calcium build-up and staining

Calcium build-up and staining occur when your pool is unable to maintain its chemical levels. In this case, there will be a build-up of calcium carbonate and calcium silicate. It is easier to clean your pool if it has a calcium carbonate build-up, unlike calcium silicate. However, the presence of both will require you to drain your pool completely and replace it with fresh water. Calcium silicate is responsible for the staining of the walls around your pool area. Some chemicals can help take off the stains, but it takes months to get them completely off the walls. It would be best to drain the pool and then clean off the stains before refilling with fresh water.

Copper also causes staining in the pool. The copper ions develop when your pool comes in contact with low-quality salt or copper-based algaecides. This only occurs if you installed s copper piping in your pool heater. If the leftover copper is not completely removed, and then your pH level is high, the result will leave stains on the surfaces of your pool.


There are many other reasons when you need to drain your pool, but these are the top reasons. If you have made up your mind to replace your pool water, it’s pretty easy to learn how to drain a pool by yourself.   That way, you save more money than when you hire someone to do it for you.
