My septic pump just failed, I am in Moultonboro. I called Lamprey's septic service, they were there with in a few hours, had the tank pumped out and a new pump on order within a couple hours after that. New pump to be installed tomorrow. I've used them for years, great service.
What does that have to do with your request? Well when I called Lamprey's they told me the truck was on a barge coming back from an island. I would give them a call and see if they go to Rattlesnake.
