Hey Guys! I have a rental unit and there is an outdoor spigot that I would like to leave available for guest use. However, I am VERY concerned that all it will take is one careless guest or child to leave the hose running overnight and BAM my water bill is through the roof. Is there something that I can install so that they can turn it on whenever but it will shut itself off after a few minutes? Something like the outdoor ones at the beach that you have to press and they stay on for approx 20- 45 seconds?
