Solar pressure cylinder replacement

[Chriswills]

I have a leaking pressure cylinder used for my solar. Is it easy to replace without losing any of the transfer fluid?

Photographs may help.

Why do you think the pressure vessel is leaking ..?

 

And no, not possible to change that without at least a partial drain down.

I can physically see it coming out of a pin hole. I’ll have to drain and change then.

If you take the pressure out of the system and only remove the one component you may be able to swap it without too much hassle.

Can you isolate it, loosen the joints, swivel down and remove?

Can only relieve the pressure but it will still be connected up I think. Here is a picture of the spec. Worth getting one of these or another type?

Zilmet are a decent brand - it’s lasted 13 years so that’s good !

To remove, is it just a case of removing from the rear bracket and twisting it off?
