How long after soldering copper fitting do you need to wait B4 you can run water thru


I just did my first copper pipe soldering, how long do you have to wait before you can water test the fitting?

Long enough for the solder to cool which is about 30 seconds after you take away the heat.

Wow, so after like 1 minute I can run water through the connection I just made?

What about pressure on the fitting? Like how long until I can treat it like a fitting thats been there for a year?

As soon as you put water in it.

Well Im done. One connection was squirting water and the other had a stream running down it. I did a bunch of researching before trying and I still couldnt get it so Im just going to pay someone to put some copper to pvc fittings on and go with pvc.

Not related but still funny anyway.Yesterday i was doing some pluming for a new toilet nile and just finished soldering the cap on the end of the toilet line and forgot to wait till it to cool and turned the supply on while on my knees and the cap shot right off like a bullet and hit me square in the balls.Hurt like hell but i learned from that one.I usually use a wet rag to wipe every joint i make right after i solder it.It cools it down and helps the pipes from turning green in time.

The choice is yours if you want to pay someone, but PVC is not to be used inside a house on domestic water. Use CPVC or PEX, or copper and push fit fittings

I had to laugh. This is a lot funnier when it happens to someone else.

Umm yes, it is within a minute, that you can turn back on the water. It will be as good as any soldered connection, that is a year, two, five, twenty, etc., as long as the person that does it properly knows how to sweat a joint properly.

Copper turns green, which is called Patna, which is a natural process. Has nothing to do with cooling it down after soldering a joint.

Ty for clearing this up for me i allways thought the flux helped it turn green faster when not wiped.
