Our bill for a family of 3 just jumped from $180 to $205, and we haven’t changed any habits. We are on the payment plan where the monthly bill is averaged to remain the same, so this shouldn’t reflect a one month jump, but a permanent increase.
I do think I’m going to check our toilet for leaks, though. Our downstairs toilet is who-knows-how-old, and it wouldn’t surprise me if it leaked. Thanks for the ideas!
