No advice here, but sending plenty of empathy. I just had the same issue—unexpected increase in water bill from $50 to $120 over a 5-wk period for my two-story end unit condo on a slab in GA. No signs of interior water damage. I did all the YouTube DYI tests. Plumber verified integrity of toilets, water heater, drain lines, outdoor spigot etc. He probed the landscaping but came up dry. No sprinkler system. County water crew came out twice to check the meter integrity. “Big mystery”they all said, until Wed 1/3 when water started bubbling up through the seam where the sidewalk curb cement meets the parking space asphalt, 12 ft from my front door.
County came out twice in 14 hrs and said it was a water line break ”on the condo side, maybe under the slab or the front landscaping”. They shut off my water because it was now gushing out. I had no choice but to hire a leak detection company and they put an X over the break. Condo property management (gleefully) declared I am responsible for all repair costs. Six days later I’m still without water, waiting for plumber, and facing a 5K+ repair not covered by homeowner insurance <sigh>. Like Nonna says,
Whadyagonna do? yagodda fahgeddabahdda.
