How do you solder copper pipe fittings?

How to Solder a Hole in Copper Pipe

  2. Apply flux around the hole.
  3. Heat the pipe and melt the solder.
  4. Clean off any drips.
  5. Let the patched pinhole cool before you turn on the water again.
  6. Replace the entire section of pipe as soon as possible.

What kind of solder do you use to solder copper pipe?

Types of Solder Buy lead-free solder that’s designed for copper water pipes; you’ll find it in the plumbing section of the store. Solder with lead is still available, but the lead can leach into your water supply, so don’t use it.

Are soldered copper joints strong?

A soldered four-inch Type L joint has a pressure rating of 440 psi. If the plumber in the field decides to braze that joint rather than solder it, the rating will be reduced to 293 psi — the annealed rating.

How long after soldering can you turn water on?

If you followed these instructions, the joint is likely very tight. The only good way to test is to put pressure on the joint (turn on the water to the house). Be sure to wait until the solder has cooled (2-3 minutes) before pressurizing the line to avoid the solder cracking due to a quick change in temperature.

Can I use electrical solder on copper pipe?

Electrical solder is often a softer alloy, so it won’t withstand pressure as well. Definitely flux the pipe fittings as you normally would. You won’t get good coverage with the flux in the solder.

How long should I wait to turn water on after soldering?

What solder do plumbers use?

Tin-antimony Solder: Contains 95% and 5% antimony. Lead-free and safe for water supply lines. Designed for use in plumbing applications where frequent extreme temperature changes and vibrations occur (refrigeration, cooling equipment and heat ducts); can also be used to solder electronics.

How much weight can a solder joint hold?

I get the ones that can hold 50Kg that is around 110 pounds. yeah, solder ain’t gonna do it….Is solder strong enough to be substituted for welds?

Solder will not work. You are screwed, try the JB-weld along with duct tape and cross your fingers.

Can you sweat copper pipe without flux?

If there really was no flux then you have a “cold” solder joint. The solder may stick in spots but it will not have “wicked” into the “sweat” joint properly and will not completely seal the joint.
