I set these up instead of using foam poppers because I have a pyromanaiac in my colony, and Ive noticed even when there is a big ass fire directly under one of these sprinklers, they still do nothing. I'm pretty sure I have plenty of water set up for them; 2 water towers and 4 electric pumps with 2 wells, the water towers are pretty much instantly filled even after the hydroponics and fertilization sprinklers go off in the morning.

The fire poppers just go off when a fire is in their radius. Why aren't my sprinklers?
