Leaking zinc gutter pierced by corrosion: why? Emergency repair and what lasting solution?

[Christophe]

Pffff what a ball ...


Well I found the table: gardening / heat-exchanger-titanium-or-stainless steel-or-other-t16401-10.html

Tomorrow I will make it a subject because I took 10 minutes to find it !!

[Christophe]

And so there is a problem between zinc and aluminum ...

But what to do to avoid this?

[GuyGadeboisTheBack]

Pffff what a ball ...

Me ?

[Christophe]

No the Pope !!

[Christophe]

Uh so if I understood correctly (not sure) the only solution is to put a sacrificial metal ... there is only magnesium which is worse than zinc ...

So I will try to find some and put in the gutter ... I will see in a year if it has moved ...

ps: the horizontal part is not corroded at all ... it should be too, right ??

[GuyGadeboisTheBack]

No the Pope !!

Are you stupid, have you been drinking or both ??? I just asked a question ...

[Christophe]

You have to try with a millivoltmeter to see if there is current.

Any questions?

[GuyGadeboisTheBack]

You have to try with a millivoltmeter to see if there is current. <<< that is just logical

Any questions?

Yes:

Unlike Bozo, my "no" is not rhetoric, and since I said I was bad at electricity, it was a question. Moreover, if I ask it, it is because the answer interests me, I am always happy to learn things in areas where I have gaps.

[Christophe]

Stop doing your Obamot ego!

a) You advised to take an electrochemical measurement: OK that's fine with me!

b) I ask for details on the measurement

c) You say you know nothing about electricity!

Conclusion: it is the fuck up there!

In short, no big deal, we've seen worse here!

the aluminum of your panels is not in contact with your gutter? I do not really see how there could be galvanic corrosion with rainwater which is moreover very little conductive… Moreover I think that the flow of water of your gutter would be more impacted than the downpipe….

I must ask my nephew about this…. He is not a chemist but a roofer ... His specialty is listed buildings ... Well, he must not see a lot of aluminum on this kind of roofs….
