We purchased an old house (built in 1915) last August. The previous homeowners, who had lived in the house for 19 years, told us that the septic system was "maybe somewhere on the east side of the house". They had never had it pumped.
We had the home inspected & the inspector did a dye test for the septic system. He looked on the east side of the house & saw no dye, so we were reassured that everything was good.
I contacted our county to see if they had any records of the location of the septic & of course, they don't have any records before 1978 (and definitely nothing about our house).
I have a problem, though: All of our drains are very slow. I also know that you're supposed to get the septic tank pumped every 3-5 years. If the previous owners never pumped it (and I don't have any sewage in the yard), should I just go on like everything is ok? Should I have it located by a professional? Is there a way to do this myself? Is it possible that there isn't a septic system, since the house was built in 1915?
Thanks in advance for any advice!
