Direct answer
Water near a hot-water system may come from condensation, a connection, a relief discharge or a failed tank. Do not plug a relief outlet or repeatedly operate safety valves to stop it.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Loose or failed plumbing connection | Observe the source from a safe distance |
| Normal or abnormal relief discharge | Note whether flow is constant or only during heating |
| Tank corrosion or split cylinder | Check the manufacturer guide |
| Condensate from a heat pump or flue system | Keep clear of hot water and electrical parts |
