That’s always a possibility. Have you checked your meter? Their mention of “constant flow” indicates a leak. You should see your meter running when all faucets are turned off if that’s the case.

I guess I could I believe it's on the other side of the fence in the woods.

"Could the utility company have a wrong reading?"

This is the most difficult kind of question to answer with a degree of certainty. To do so require's putting one's self into near trance before looking at the situation. I did so and was more than half way through looking at utility company's field and office staff as well as their book keeping system when it dawned on me. If only I could conjure up the last few bills you recieved and the present meter reading,I could answer your question of "Could the utility company have a wrong reading?" I'm so sorry but I broke a sweat that got in my eyes while looking at the utility company's inner workings and couldn't go on. Perhaps if you can take time to geather those bills and present meter reading,I can answer your question with accuracy. I await the information and look foward to helping you.

Do you have a bathroom that’s rarely used? Could be a toilet flapper that failed to seal until it was flushed again. Odd for a leak to stop on its own. My water company sometimes estimates, so their figures are different than when I read the meter. Once they were 20,000 gallons off. Good luck.

Very possible. It's just me and I have 2 bathrooms, I just recently started using the second bathroom. I never heard it running.

Almost always a toilet.

Very rarely a meter issue.
