Your on-call plumber should hear about the burst pipe right away and the dripping faucet tomorrow. The difference comes down to a short, written list.
Start with water you can’t stop
- Burst pipes and active flooding
- Sewer backups into the home
- No water at all
- A leaking water heater
Then decide on the gray areas
A toilet that won’t stop running at midnight might be routine for one shop and urgent for another. Pick a rule and write it down, so every caller gets the same answer.
Review it every season
Frozen pipes in winter and storm flooding in spring change what is urgent. Look at the list each season and adjust it.
