  • In swimming pool locations where a horse can reach the pool.

  • Showers and bathtubs, where water outlet has an extension that can be submerged. Most probably extension hoses connecting onto the bath spout.
  • Handheld toilet sprayer as well as the chemical plant.

If there is no adequate measure taken in time, water backflow poses a big risk to you, your family as well as people in your neighborhood. By consuming this contaminated water may result in becoming ill to various dangerous diseases.
