Chapter 803 - 360 Blood Heart’s Blood_3
Lin Wu glanced at the men’s and women’s changing rooms, then walked away and reported, "There are many zombies, don’t make too much noise." The number of zombies in the two changing rooms was even greater than the number of zombies in the swimming pool. Lin Wu saw the cabinets filling up the two rooms and couldn’t help but feel an itch in his hands.
"Drain," Maya pointed out, next to Blood Heart, at a square cover, "I don’t know if there’s a valve."
Lin Wu said, "Even though I don’t understand, if there’s a valve, the person who turns it will get stuck by the suction and freeze to death alive."
"Not drown?"
"You’d freeze to death before drowning."
"The water isn’t frozen, which indicates the water temperature isn’t very low," after saying this, Maya crouched down and touched the water, "It’s extremely cold, it must be circulating water." Her face felt a bit painful.
Many swimming pools are equipped with circulation systems, continuously draining water. After rudimentary purification and treatment, the water is returned to the pool through the inlet. This is because pools generally only have a two to three months usage season, and the cost of changing the water completely is too high, so this method, along with chemicals such as bleach for disinfection, is used to maintain clean water.
Maya said, "There should be a dedicated equipment room. If I’m not wrong, we need to open the drain cover first, then start the drainage equipment."
