avoiding a disposal is right on advice for septic. the biggest
mainanence item is to get it pumped regularily---2 to 5 years depending
on how much use it gets. if you don't, the tank will fill up with
solids, and then the solids start washing into the drainfield and plug
it up. If you don't know when it's been pumped last, pump it now. i
don't believe in the additives. just keep it pumped regularily.

After living with city sewer systems for 75+ years we now are "proud
owners" of a septic system and about to be two systems. New
woodshop/garage will have half bath and sink for cleanup on a septic.
Have read don'ts like using bleach down the sink that will kill off
the critters that make septics work and some other tips but would
really like to go to a comprehensive site for more info. Does one
exist? Shortly after moving in a phone solicitor asserted we HAD TO
use their product monthly or we'd ...! Our DIL uses something monthly
but I question 3-5 ounces down the drain into a 1,000-1,500 gallon
tank having a significant impact. Permit for new septic notes that
1,500 gallon system is required for disposal houses. Previous owner
apparently had a disposal as a switch near the sink doesn't connect to
anything and wires under the sink terminate in wire nuts. Our house
septic is 1,000 gallons. Observations welcomed.
