That being said I bought a house 3 1/2 years ago. I have had issue with the septic system since day one. I have paid a company around $1000 a year(a few different issues). I don’t mind paying to get something fixed but it seems like maybe they don’t know how to fix it. They installed the system FYI. So from what I know the system is on a timer as not to over tax the drain field. What happens is the relay clicks on and off then over and over and over about 1 minute apart. My problem is the relay is located below my bedroom window and at 1am it’s very annoying. If anyone has any ideas please let me know. The video is above. The clicking or relay happens once every minute for about 10 minutes.
