I think we've got an issue. We moved in last May, after the house had been very lightly used for about five years - the owners died, and their son used it as a weekend place occasionally.
He assured us that the septic tank had been recently emptied, but we noticed it overflowing and generally being a bit whiffy - so we assumed he was mistaken, and had it emptied. Now, barely six months later, it's overflowing and being a bit whiffy again. So the obvious conclusion is that the drainage field is blocked up, right? There's damp bits of garden below the lid, and nowhere else that we've found.
It's an old-school square two-chamber concrete pit, right on the boundary with next door - so the drainage field is either going to go under their garden or be inevitably compromised in design.
Short of getting a JCB in, is there any realistic hope for any of the "healthy tank" products? The postie brought a shiny leaflet for "BioGard Muck Munchers" this am -
What reckon you lot? Waste of money, or flushing good money down the bog?
