Help! Massive Water Bill Mystery in My 3-Unit Building
This morning I tried to get to the bottom of my insane water bill.
-
Shut off the main water supply to my 3-unit building.
-
Checked the meter — it stayed completely still.
-
Turned the water back on — meter started moving right away, so it’s working fine.
Here’s the history: my water bill used to be about $475/month. Then it suddenly jumped to $700. I called the city, and they came out and installed a brand-new meter. After that, it went down slightly to $500… but now my latest bill is a whopping $1,500.
From my test this morning, it seems there’s no leak between the street and the building — the extra usage is happening inside. One unit has 1 tenant (rarely home), the second has 4 tenants, and the third has 5 — but the total usage is way above normal.
Has anyone dealt with something like this? How did you figure out which unit or appliance was causing the spike?

Check all toilet flappers - Those can cause a tremendous amount of water usage if not sealed properly.
