Honey, the house I grew up in had plumbing issues and TWO illegal-by-todays-standards septic tanks. We could not even flush toilet paper, which is likely what made me into the shameless person I am today. There is nothing anyone could tell me about old pipes and - uh - backups that would gross me out, because chances are good I've had to deal with it.
We have a picture, somewhere, of my dad, in his constable uniform, digging the drainfield for the one in the front yard, grinning.

(And I've certainly dug up my own septic tank a couple of times!)
