Hi,
I recently tackled my own project of replacing a hot water heater with a new one (electric). The heater used 3/4" copper pipe. I had no problems except with a new water gate valve on the inlet side. I replaced the old with an exact new one but now I have a leak that drips one drop of water about every two minutes.
Question:
- Should these gate valves be dissembled prior to soldering so the heat won't affect the o-rings inside ? Mine is leaking at the solder connection, not from the top or the valve stem, but I wouldn't want to chance damaging the o-rings.
- Should I try heating the fitting up again and apply more solder to stop this very tiny leak or just cut it out and install another new one ?
- I used the proper soldering techniques (cleaning, flux, dry pipes, etc.) but any pointers will be appreciated. This fitting was the only problem I had.
Thanks very much in advance.
