‘Plumber to fix leaking boiler in SE19’ – boiler repair blog

I got called to diagnose and repair a suspected boiler leak in SE19, Crystal Palace. The client actually used the phrase ‘Plumber to fix a leaking boiler in SE19’ to find me on Google.
When I got to site I was met with this massive leak coming from the boiler pressure relief valve that has soaked the whole wall.

I quickly noticed that the filling loop was passing and over pressurizing central heating system causing a continuous leak of hot water. On top of that the pressure relief pipework was going uphill making water drip on to the pipe and into the wall. On quick examination I also found something rather strange. The magnetic filter was fitted with a bypass (the filter was not really doing much) and on top of that one of the soldered joints was leaking. Generally the installation was really shoddy. When I asked the client when it was installed it turned out that it was done only 3 years ago. Also, the boiler was a direct swap and the client paid £2600 for supply and fit of a budget boiler. Something wasn’t quote right. I checked paperwork and a quick Google search of the full name of the installer came back with BBC rouge traders article. It may be a good idea to google your installer if you are looking to have your boiler replaced! That could have saved a lot of grief in this case.

Coming back to the repair, what has been done to remedy the situation:

  • replace pressure relief valve
  • re pressurize expansion vessel
  • replace filling loop with a compliant filling loop with 2 stop taps
  • remove filter by pass and at the same time repair leak to the pipework
  • change angle of pressure relief pipework
  • replace leaking magnetic filter with new Magna Clean Pro 1 filter
  • add inhibitor to the central heating system
