Gentle Reminders When Draining Your Pool


Aside from the different approaches to draining your inground pool, here are also some reminders that you should consider before even trying to drain your pool on your own. 

Right Water Level for Different Circumstances

If you are draining your pool for closing, it is best to stop the draining process when your pool water line is 4 inches below the skimmer. This should also be the case if you are planning to winterize your pool. 

However, if you are draining your pool for maintenance, it is best to drain all the pool water completely. This way, you can easily clean your pool’s surface and add fresh water to your pool.

Know the Law

Familiarize the law of your city in regards to pool draining. Each city has a different law which is why you should know yours first before performing pool draining. It is best to do your research first before even planning to drain your pool on your own. 

You can as well talk to families or friends that have done pool draining before. You can also check your city’s website as they usually post information regarding this matter on their sites. 

Be Aware of Pool Pop  

Be aware of pool pop during draining. Yes, you heard it right, and as the name suggests, a pool pop will pop your pool, damaging the structure, plumbings, and even damaging your pool lights. 

If this happens, there will be a serious risk of electrocution. Plus, your homeowner insurance won’t even cover these damages. The best way to avoid this is to hire a professional pool cleaning company like the Aloha Desert Pools to do the draining for you. 

Not only will it ensure that the draining is carried out properly, but you can also save a lot of time and effort in draining your pool on your own.

If you live within Arizona, it has been a custom to drain inground pools every 3-5 years. However, this should not only be practiced within Arizona State, as draining your pool once every 3-5 years is a must for every swimming pool across the globe.
