<prompt> Human: UPDATE 1: I was able to get them to schedule a meter test for Thursday afternoon, so well see how that goes. Thanks for your comments, guys. The most popular answer here was that its a leaky toilet. I still have a hard time believing our toilet would just randomly leak profusely for four days and then suddenly stop, all without us noticing. It also doesnt quite explain the large variance in gallons over those four days. That toilet would also have to be producing over 5.5 gallons of water per minute, which seems like a bit more than just a quiet stream. Im open to hearing more about that though.UPDATE 2: The test came back 100 accurate, so the meter is apparently not at fault. At this point, I have to accept the possibility of a very significant leak from my toilet that happened without my knowing. Ive reached out to the water company and escalated the issue to management. I explained to them the situation and that a random 500 water bill with no confirmed source of a leak isnt acceptable and not something Im willing to gamble with in the future. Hes going to get with his higher ups and see what kind of options they can provide for me as it is a bit of a unique situation. Meanwhile, Im having a plumber come out to take a look at our toilet. Im hoping for a leak adjustment.I recently received a 90-day water bill for 500. This is more than double what Im used to paying. The bill was for 35,000 gallons of water used over 3 months, and were just two people in a small 800 square foot home.Upon reading the daily report, I came across four consecutive days from January 27th through January 30th where 20,000 of those 35,000 gallons were used. See here: I looked back to see what we were doing during those times -- nothing out of the ordinary. We were home. It was the middle of winter in the midwest, and everything was frozen and covered in snow.We did check for leaks and there were none, but a leak that significant wouldnt have just fixed itself anyways. A burst water pipe wouldnt have fixed itself. I find it highly unlikely anyone couldve hooked up to the spigot on our driveway for four consecutive days while were home with our three neurotic dogs. The water company is holding me liable for this charge, and theyre not listening to anything I have to say. Is there any way I can prove this wasnt my doing? I dont even know how this level of usage couldve happened. Is a faulty meter possible?Assistant: Someone was building an outdoor ice skating rink in their backyard and decided to use your water hose?Human: I just dont see how itd be possible for anyone to use our spigot. The only accessible spigot is right next to our main door just outside of where we spend most of our time, and facing the driveway. If it was in use for four consecutive days, we would have known.  <response>: Does your neighbor have an indoor pool by chance?
