The Problem
My water bill doubled last month and I have no idea why. I haven't changed my habits, I don't have a pool, and it's just me and my partner. The utility company says the meter reading is correct. I'm paying $180/month for water which seems insane for a 2-person household. Something is wrong but I don't know where to start looking.
The Plan
Week 1-2: Find the Leak
Check your water meter: turn off all water in the house, read the meter, wait 2 hours, read again. If it moved, you have a leak
Check all toilets: put food coloring in the tank and wait 15 minutes. If color appears in the bowl without flushing, the flapper is leaking — this is the #1 cause of high water bills
Inspect visible pipes for drips: under sinks, behind the washing machine, water heater connections
Check your outdoor spigots and irrigation system — a stuck sprinkler valve can waste thousands of gallons
A running toilet can waste 200+ gallons per day — that's $50+/month in many areas
Week 3-4: Reduce Usage
Replace toilet flappers ($5 each) — even if they're not visibly leaking, old flappers waste water
Install low-flow showerheads and faucet aerators — $10-20 total, saves 20-30% on water
Run dishwasher and washing machine only with full loads
Water your lawn early morning or evening to reduce evaporation — or reduce lawn watering altogether
Fix dripping faucets immediately — a faucet dripping once per second wastes 3,000 gallons per year

Follow-Up Result
4 weeks in: found the culprit — a silently running toilet in the guest bathroom. The flapper was worn out and water was constantly trickling from the tank to the bowl. A $4 flapper replacement fixed it in 10 minutes. Also found a slow drip under the kitchen sink that I'd been ignoring. My water bill dropped from $180 to $105 the next month. Installed low-flow showerheads in both bathrooms for $25 total. The meter test was the key diagnostic tool — it confirmed I had a leak before I even started looking. Lesson learned: always check the toilets first.Know someone with this problem?
