Don't understand
If they have been buying Tide HE, why switch to cheap liquid, or the homemade soap mix ?
Why not try liquid All (free n clear) or some such... Most liquid detergents say that they are septic safe?
Use some hot water, for white loads, and clean the screen once in a while, with CLR or something ?
Might be a good idea to empty the hot water tank to get some of the hard water build up out of it too.
Don't know what the addition of STPP would do to a septic tank? Launderers, or Sudsmasterter would though!
