Seeking advice on my expansion vessel

[Nicks]

I have a Vitodens 100-W WB1B 26 kw system boiler. Which I believe needs a new expansion vessel, due to when I tried checking the pressure in this vessel, I had water spray out from the valve ..... Am I right that a split may have occurred ?
If so, is it a simple job to exchange new for old vessels over ???
As my friendly plumber at present is on his holiday :sunny:

sorry to say if the expansion vessel is located in the boiler you need to be gas safe to change/ take the case off the boiler so no

Thanks Shauncorbs.

I just believed it may have been a simple job, alls still working ..... but I wanted to understand if there may be damage being caused at present ........ not realising I would be tampering with the gas.

I will shall await my friends return in three weeks time then :-(

Thanks again

Nick , it could be a quick job but , even if you dont touch the gas it is illegal to take the case off .

Nick, to clarify, as my esteemed colleague's have mentioned removal of the case may well form an integral seal on the boiler which is obviously there for your safety. If you take it apart you won't have the tools or the know-how to test this has been put back properly

Understood Jdl.

As a temporary fix isolate and drain out a rad then open the valves again as this will act as an expansion vessel for a few weeks.

Why not fit an external vessel, no rules broken. Remember to add inhibitor once finished.

Doing this now, many thanks Millsy for your positive help.

Thanks Duncan but I've ordered the replacement expansion vessel, as written in the Vitodens parts list manual (014).

Just have to wait for Suntan man to return in 20 days. With a radiator now acting as the expansion vessel for the time being.

I would cancel the order for the minuite , you may not need one
