Not actually prepping as such but hoping someone will have some experience of this and be able to advise - we live in an old house with a septic tank, sadly the soakaway/drain field/leach field is very very soggy. I believe this means that a "biomat" has built up around the soakaway pipes and restricting drainage?
My question is - has anyone tried the drain field restorer liquids? And if so did it work or am I going to have to dig the field up?
We're taking extensive measures to reduce water usage (have 3 teenagers in the house though

).
Tank was emptied last summer.
