I just recently moved into a home with a built in pool and spa and have 0 experience with them. About 3 hours ago the jets for my spa turned on. The heater is on standby and we did not have anything for the spa turned on. It is the first time raining since we have lived here, so not sure if that has anything to do with it. The water level in the spa is also really low. Does anyone know why the jets are on and if there is a way for me to turn them off, that is if I should turn them off??
