Quick answers
- Toilet flappers are the usual silent bill spike.
- Meter that moves with all fixtures off → call for leak detection.
- Irrigation left on after storms wastes water and can soak foundations.
- We quote leak detection and repairs flat-rate after we see the pattern.
When to use this guide
When the utility asks for conservation, your bill jumped, or you hear intermittent refill at the toilet.
Do this first
Dye-test toilets, check under sinks, look at the water meter with everything off, and walk irrigation zones. Photo any wet spots.
When DIY stops
Meter movement with fixtures off, slab dampness, or ceiling stains means diagnosis — not another parts run.
What we do on arrival
Isolate zones, confirm fixture vs underground vs irrigation, and present repair options. Filtration/softener electrical needs stay with electricians when relevant.
Failure modes to avoid
Ignoring a running toilet because “water is cheap”
It adds up — and drought rules can tighten. Fix the flapper.
