How do you measure a pipe for a shut-off valve?

Quote from the video:
Quote from Youtube video: The inside diameter of the pipe is a half-inch you have to allow about a eighth inch for each side of the wall.

What is correct about copper tubes?





Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper.

What size copper pipe is used for water?

Use this rule: The nominal pipe size of a copper pipe is always ⅛ inch less than the actual outer diameter.

Should I use type L or Type M copper pipe?

When to use Type L and Type M copper pipe sizes. Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine.

How much length do pipe fittings add?

The length must include the distance between the fittings and the extra reach that goes into the fittings. If you are using 1/2-inch pipe, add 7/16 inch per end; and add 1/2 inch per end for 3/4-inch pipe.

How do you install a shut off valve for copper pipe?





Quote from the video:
Quote from Youtube video: Put the ferrule over the top. As. Well make sure it goes down all the way it can't be partially down it has to be all the way down so it slides down the pipe. So that way we can slide the valve.

What’s the difference between red and blue copper pipe?

The color assists in identifying the type of copper pipe. Green represents type K, blue represents type L, red represents type M, and yellow represents type DWV. Thus, type L copper pipes are also known as blue and type M copper pipes are also known as red.

Do plumbers still use copper pipes?

No longer is copper piping the primary, or preferred, choice of most homeowners and plumbers. Cross-linked polyethylene flexible tubing—commonly called PEX—has grown in popularity for residential plumbing over the past few decades as an alternative to traditional copper and chlorinated polyvinyl chloride (CPVC) piping.

Why do plumbers use copper pipes?

Durable: Copper is the most dependable and most used material for plumbing tube in the developed world. Copper is beneficial in underground applications because it is highly corrosion resistant in most underground environments. Because of its superior strength it can withstand stresses without failure.

Is PEX better than copper?



PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.

Why do copper pipes go green?

Patina, or the greenish colour that appears on copper pipes, happens from oxidation. Oxidation is common on copper when it is exposed to water and air over time. While this oxidized layer is not harmful, it does cause the copper to become corroded.

Which is stronger L or M copper?

However, in certain jurisdictions, you can find that they require type L pipes to be used. Water pressure is the primary cause because some municipal water sources require high water pressure to meet the demand. The thicker L copper pipes can withstand higher pressure than the M copper pipes.

Is copper shiny or dull?



Appearance and Hardness of materials

Object /Material Appearance Hardness
Coal Dull Not very hard
Sulphur Dull Not very hard
Aluminium Shiny Very hard
Copper Shiny Very hard

Is copper ductile and malleable?

What are disadvantages of copper?

The Disadvantages of Copper Wire

  • Cost. Copper costs far more than fiber optic cable. …
  • Corrosion. One of the most serious disadvantages of copper wire is its susceptibility to corrosion, that is, oxidation. …
  • Shock Hazard. Fiber optic cable has a lower shock hazard than copper wire. …
  • Bonding.



Why don’t we use copper pipes?

Although copper costs less the steel, it costs more than plastic. Copper pipes also encounter problems from water acidity, so they are not good to install for plumbing systems that draw water from a well.

Is copper plumbing better than plastic plumbing?

Copper lasts longer than PVC pipes.



It’s tough to beat copper pipes for longevity, which on average last 50 to 70 years, compared to PEX, which has an expected lifespan of 30 to 50 years.

Can copper pipe last 100 years?

Regardless of the material, each of these plumbing products have a life span that you should know so you can gauge whether you need an upgrade. Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years.

Why do my copper pipes get pinholes?

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.

Should I replace copper with PEX?

Coupled with low production and shipping costs, the savings resulting from installing PEX instead of copper pipes can be significant. Better Energy Efficiency – PEX has a lower thermal conductivity rate than copper. As a result, PEX pipes can help keep hot water hotter for longer periods of time.
