Understand pool plumbing basics to visualize what a pool tech might do to fix the leak. The basic configuration of a swimming pool plumbing and filtration system is simple. Water is pulled through the skimmer and main drains in the swimming pool by the pool pump. The water travels underground to the mechanical room where it passes through the pump strainer basket and is then pushed through the filter and heater as well as any other peripherals such as chlorinators. It is eventually piped back to the pool through the return lines.

What happens if a pool leaks in the winter?
And in the most extreme cases, a leak left unfixed when the pool is closed for the winter very well can lead to a pool being destroyed beyond repair.

Leave the bucket alone for anywhere between 3 to 7 days and do not top off the water, checking regularly to look for a change.

If both levels have dropped equally you simply have evaporation – this test is most effectively done when temperatures are cooler at the beginning or end of the season. Even though the two bodies of water (the pool and the bucket) are vastly different in size, the rate of evaporation will be consistent.
Why do you need to top off your pool?
The cost of topping off the pool regularly adds up little by little in the form of a larger than normal water bill, or electric bill if you are on a well.
