The ratings dont go low enough to indicate what we think of this service, worst experience ever. In the twenty seven years we've lived here never has there ever been any mess left behind after any of the six times we've been pumped. They showed up here with an almost full tank and couldn't pump our entire tank but worse of all was the disgusting sludge left on several places on our lawn when they put their hoses away. We will never use these people again.
