Is muriatic acid safe for septic system?

Q.    I read your advice regarding the calcium ring in the commode problem. Is muriatic acid alright to use in a home that has a septic system?  We have 8 toilets and before I empty 16 cups of the acid into our system I just wanted to check.

A.    Muriatic acid is very strong and, of course, not the best thing to put in a septic system, but it is greatly diluted and weakened after sitting in the bowl overnight.

One cup of muriatic acid is enough per toilet and you don’t have to do them all at once. Stagger the treatment over a few weeks.
