The fault

When your boiler is leaking water

A leaking boiler is usually a failed internal seal, valve or corroded pipework, or pressure being forced out through the relief valve. Left alone, leaks cause corrosion, electrical faults and can damage your home.

Switch the boiler off and place a container under the drip if it’s heavy, then book an engineer. Never seal or ignore a boiler leak.

Common causes we find

  • Perished internal seals or gaskets
  • Faulty pressure-relief valve discharging water
  • Corroded heat exchanger or pipework
  • Loose or failed pump and valve connections
  • Over-pressurised system pushing water out
