Can you use too much flux when soldering?
One, using much more than needed will basically drown your joint making it hard to heat to the right temperature, two, flux needs to be removed before a part is returned to service so every bit used that is more than needed makes for more clean up.
What kind of solder should be used on water pipes?
Lead-free plumbing solders are required for use on pipes carrying drinking water, also known as potable water lines. Leaded solders are available for applications that will not come into contact with potable water, such as sheet metal repair or copper drain lines.
What causes pinholes in copper pipe?
The primary cause of pinhole leaks is the composition of the water flowing through your plumbing system. Hard water—high amounts of dissolved calcium and magnesium—or water that is too basic (low pH) or too acidic (high pH), can all contribute to copper pipe corrosion.
Can copper pipe be welded?
Copper and most copper alloys can be successfully joined using welding, brazing or soldering processes. … It is also the method used by plumbers to join and repair copper pipe and copper fittings. You can use an inexpensive soldering iron or a blowtorch with a suitable flux for soft soldering.
How do you insulate underground copper pipes?
Cut rigid foam-board insulation into strips that are 12-inches wide. Lay several of these strips, to a depth of 4 inches, on top of the plastic sheeting. Then, lay the water pipes on the insulation. Add insulation, also to a depth of 4 inches, on either side of the water pipes.
Should you wrap copper pipes?
Many homes have uninsulated copper and Pex pipes that run through the basement ceiling joists. If the temperature drops below freezing the cold-water pipes can freeze. … Wrapping the pipes with this insulating material will help to keep heat energy inside which will protect the pipes from freezing.
What is the best pipe to use for underground water line?
HDPE (High Density Polyethylene) pipes are a considered the best choice for underground water lines. What makes this type of piping so great? HDPE pipes are non-toxic, tasteless, and considered a green building material. The pipes are designed to be high crack- and corrosion-resistant.
What is the difference between red and blue copper pipe?
M/Red is lighter duty, generally used for hydronic heating. It is permitted by code for domestic in SOME areas. L/Blue is a medium grade, suitable for domestic or hydronic heating.
How long will copper water pipes last?
