I just want to superglue old aluminum heatsinks on the water inlet pipe, but people are going to think I’m nuts…

I have to admit I haven’t thought out whether this will galvanically disappear the copper.

I’ve also thought out putting a 50’ spool of pex inline, but unsure of pressure loss issues. Or maybe that would be good for the house pipes…
