It is possible that the tank you are looking at is abandoned. I would start with flushing toilets in the house to determine if there is any flow coming to the tank. It would be very odd for it to be full of sand unless the sand was intentionally added to the tank. More than likely the plumbing has either been hooked up to city sewer or a new septic system has been installed at one time and a new tank was set as part of the new system.
@@askthepumperdude there’s not a new system, the owner had a pump company come out and they said he had to get someone else to get the sand out. We are looking into fixing the property up for the owner. So we was trying to figure out how to go about getting the sand out without having to put in a whole new system. It’s an old property.
Is dirt at the bottom of the tank a sign of a leak? My technician didn't seem very knowledgeable but he said it was. I have no other symptoms of a leak, and the system works fine, but there is some erosion under the border of my pavers near the tank. But I live in Florida so I'm unclear if it's natural or from the leaking tank.
My first guesses is that this is either a chunk of styrofoam or it could be grease build up from food waste or possibly build up from powder laundry detergent. Styrofoam won't really hurt anything and can easily be removed using a hook to grab it. If it is food waste or detergent build up, it needs to be broken up by your pumper and removed during the tank cleaning.
