The village idiot we used before was charging $250 and wanted to raise the price to $280.
We ended up seeing an ad in a local paper for another company for $180.
When the new company came, we found out the village idiot was only taking the liquid and leaving all the solids
The new company did the correct job cleaning it and luckily no damage was done to our septic system.
EDIT
Village idiot is based out of Quakertown PA and has "Polish sounding name" that begins with a K
The upstanding and honest company is Robbins out of Green Lane PA and is highly recommended.
