I turned the water on to my sprinkler system last night. First problem
was that I forgot to shut the drain valve. I was wondering why I wasnt
getting any heads to spray when I went to the valve to find a small
growing pond. Closed the valve, problem solved.
Next I noticed a small leak in one of the fittings on the water supply
line. Can anyone tell me what these fittings are? Freeze protection?
The two things on top of either upward pipe are what I'm talking
about. If you look closely you can see a bit a spray coming from the
one on the right. They have an opening about 120deg I assume is to
spray water away from the house when they break.
The entire assembly is soldered together. What kind of torch will I
need to break this loose? I assume a typical propane torch will not
get hot enough fast enough, but I'm not sure as I've done no soldering
of copper pipe before.
Both of these fittings also have a hex cap on top(see photo), which is
also soldered. Is it possible to fix the fitting by removing this cap
or is the whole unit junk?
