Boiler Leaking from the Pump
Pump leaks come from worn seals and usually mean a pump repair or replacement.
Water from around the circulation pump points to failed pump seals.
Why pumps leak
Over time the pump's seals degrade and weep water from the pump body — a common bottom-of-boiler leak.
The fix
A technician replaces the pump seal or the pump itself, then re-pressurizes and tests the system.
Key takeaways
- Pump leaks = worn seals
- A common bottom-of-boiler leak
- Repair or replace the pump
- Re-pressurize after repair
