FAQ
Q Is it normal for the winter ball to float vertically on the water surface?
It is normal. The winter ball is not meant to be dripped into the pootI directly; instead, it works through the circulation of liquid replacement. If you encounter this situation, there is no need to worry.
Q What should l do if l receive a product with damaged packaging?
If you receive damaged products, please contact us via info@poolhacker.com, We will promptly arrange a replacement for you.
Q Do you keep the filtration system running the winter ball?
No, keep the system off. I place the ball under the pool cover ffor winter and remove it in the spring. It works great
