flux & solder ?'s

Just curious as to what flux you use/prefer?

Around here (central wisconsin) it is hard to find anything other than Oatey #5 or #95. However, it seems as though a lot of professional plumbers prefer other brands.

Also, what is up with Oatey label about mixing the flux before using. Do they not realize how thick flux is - next to impossible to mix.

Lastly, over the years I have only applied heat to the fitting with solder on opposite side of heat. Some say to apply heat to pipe itself too?

Play the flame back and forth over both the fitting and about an inch of the pipe .

When you try to apply the solder tot he far side, you are sure that the entire pipe is hot enough when the solder melts.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

I have always used Oateys. When you carry it in a truck box for a while, in high outside temps, it can separate. Normally, I just look to see if it looks "normal". When soldering, I hit the pipe near the edge of the fitting for a few seconds. This lets some heat go into the pipe. I have been told that it is possible to heat the fitting and the pipe still be cold (got my doubts about this). If this happens, the solder could solidify instead of traveling up through the fitting all the way.
If you have never made a mistake, you haven't done much.

I only use Nokorode. I always heat the fitting and pipe altering between until the solder sucks in to the fitting.
