For Those With Septic Tanks
Whoa.
My septic was "built too large" for the recommended size of house.
My house is 2000 Sq/Ft and the septic system I've been told is either "3-75" or (yes) "4-40".
Either way, it's supposedly so much larger than spec that it doesn't really need pumping.
I was told- "if five people lived there, maybe pump it every five years".
