Septic fields, am I being ripped off?

Here in the 'Burg, Roto-Rooter is only a last resort, prices always thru the roof, always find something extra, and very expensive, to add on.. I just had clogged outflow lines fixed, and a broken pipe replaced, for $750. Was quoted $15k if I want to replace my 70yr old system.

Not sure how they can say it is "ready to fail at any minute"...normally they either pass or fail a dye test,

I'd issue a stop work order, and get a second company to come in and assess the overall situation.
