Since I had not done my homework yet, I did not know what to do. I silenced the alarm and started making phone calls. Not one septic company in this area works on weekends. So I left a few voicemails and we waited until Monday.
Let me tell you the weekend was troublesome. We had hot/cold water and power, but not having the waste system working meant:
- no toilets
- no washing dishes/etc in the house
- no shower
Monday am at 7:15 I got a call from the local Roto-Rooter and they sent their tech. The problem turned out to be: the tie-wrap that held the alarm sensor broke and dropped the sensor into the liquid tank and that is why it was reporting the liquid level high.
I asked a lot of questions and learned that there is maintenance I need to do at least once a year, so it was a good learning experience. And for $150, it was not too expensive.
