garn install progress

[maple1]

Had some leaks today some Bi some solder, the strange part is some of the solder leaks are on the old system haven't been touched for 5 yrs,

Funny you mention that - I had the same kind of thing just a couple nights ago. I aired up a section of new & old 1-1/4" piping, and it was leaking at a 17 year old solder joint on the sweat side of a sweat/NPT adaptor. I might have been a bit rough on that section when I was dismantling my old boiler (had to use an extension on the pipe wrench), but I had it well supported when I was doing that. I haven't re-checked it yet since I re-sweated it. I haven't had many leaks yet (knock on wood), the ones I have had so far were on solder joints.

I've got a "leak" somewhere that is only an issue after everything cools down and it sits for an extended time unused. During the heating season I didn't have any trouble, after I stopped using the wood boiler I slowly lost all the pressure on the the wood boiler side of the plumbing.

I think it might have been yet another packing nut on a ball valve that I did fix recently. I just haven't pressured up the loop again to test it.
