It's time to drain your pool when these come into play:

  • A typhoon is approaching
  • Need of a repair or resurfacing (done with the help of expert pool cleaners)

These apply to both in-ground and above-ground pools!

Inground Pool

Ground concrete ones are commonly lined with pebble, white marble, or fiberglass.

The thing is, pools like this aren't recommended to be emptied of water in the summer.

Above Ground Pool

With this type, the weight of the water on the floor helps protect the liner.

That said, you won't want low water levels during the winter; it could suffer from structural stress.
