  1. Up to 50%

  2. Up to 75%

  3. Up to 90%

  4. Up to 95%

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A well-fitted pool cover can reduce water evaporation by up to 90%, significantly conserving water resources and reducing the need for frequent pool filling.

Multiple choice

Which type of pool cover is most effective in preventing evaporation?

  1. Solid covers

  2. Liquid covers

  3. Solar covers

  4. Automatic covers

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Solid covers, also known as winter covers, are the most effective in preventing evaporation due to their complete coverage and tight seal. They are typically made from durable materials like vinyl or polyester and provide a physical barrier against the elements.
