Soldering flux

[sigma]

I know that lately a lot of plumbers uses propress and PEX but here is a question to those who still sweat copper pipes:
What kind of flux do you like the most? What do you think about water soluble flux?
Is anyone using tinning flux? Thanks for sharing your opinion.

I like the tinning flux, but don’t do much water anymore.

The only solder made anymore worth anything is the purple label “sterling” brand, all others flow too easily and won’t fill a small gap in the joint. Sterling flows like the old 50/50 used to.

No need to use anything special when tinning a larger joint, just regular flux and solder.

I use some Oaty flux, comes in a small bucket.

I tried tinning on on one job but with multiple pipelines and lot's of fittings, I would do one side of an elbow and then the next, then the fitting close to it would have a silver ring and I would think I had done it, move on and so forth. Ended up missing 1 or 2 joints, in the toughest to get to location, so after that I stopped using it.

Any name brand. Really haven't seen much of a difference
