Water bill
A bill spike is a clue. It is not a source.
Owners see a high bill and assume a hidden leak. Sometimes it is a toilet, a hose bib, or a billing period. A careful all-off test turns the bill into a useful fact.
Compare days, not only dollars.
A longer billing period looks like a leak. Count the days.
Do a real all-off test at the suite meter if you have one.
Toilets, humidifiers, ice makers, and hose bibs count. Watch the dial.
Call if the meter still moves.
That is enough to treat it as water leaving the system, even with no stain yet.
Questions people ask
Can irrigation on common property hit my suite bill?
Only if you are on a shared meter. Ask the manager which meter you are reading.
Should I wait for another bill?
Not if the meter is moving with everything off. Waiting is more water.
