I spent a good while yesterday after noon with the spiders and snakes under my
house replacing some valves that the last plumber had installed in the wrong
sequence so that it was impossible to blow the lines clear before the first
freeze of the season. The new valves are now in place and seem to be fine but I
found that some very awkward places as I worked towards the outside faucet leak
at the unions.... maybe three out of more than a dozen that I did. So what do I
do now?

I can easily blow the lines clear now but I'm reluctant to negate any more work
than I absolutely have to in order to correct the problem. None of these leaks
are gully washers... just drip, drip, drip... but I know I will not be able to
live with them. What is the best way to fix the leaks? I'm talking about 1/2"
copper lines and fittings.



Hi,
Quickest way is redo them after cutting the joint. Sorry to say it but
poor workmanship! Clean, flux, heat properly and flow the solder. If
water drops are present near the joint stuff a piece of bread to soak it
up. When your water starts to flow break will dissolve and come out of
faucet/taps.
