Leaking - LONG PIPE FROM HEAT EXCHANGER Vokera, part no. 10023947

The pipe is leaking and I presume requires a replacement hose / pipe.

I'd like to understand:

1) Will a replacement pipe solve the leaking (The pipe leaks when cold, but no leak when warm)
2) Is the pipe replacement a simple DIY job, or is it best left for a professional ?
3) Any issues / tips to look out for when replacing the hose ?

Note: I've found the two water isolation valves to the pump, which is where the cold and hot flow pipes leave and enter the heat exchanger. I can isolate the electricity to the boiler by just unplugging it.

 

Can' see the pictures but @ianmcd can probably help if you give more information. What boiler is it?

It's a Vokera Compact 28

 

yep will need a new braided hose, that boiler has two, better to change both at the same time, they will be chocked solid as you have a dirty system, nothing to stop you doing it yourself but better to get an experienced Vokera engineer to do it and add cleanser then inhibitor

 

Thanks Ian,

What is the indicator that the system is dirty ? The boiler was serviced ~ a year ago.

 

feel the hoses they will be hard and brittle, but dont squeeze them as they will deposit all the crud into the hydraulic manifold and a total mare to get out , servicing the boiler , the water quality would never be checked , unless it was BG trying to sell you a powerflush
