The same copper is used for both and if you have a piece of pipe that was previously used for hot water you can use for cold water and vice versa. As long as the pipes are connected up properly then there’ll be no problems.

Is it OK to reuse old copper pipe?

Copper pipes are usually connected together using a variety of fittings, including elbows, T’s and couplings. You can remove copper fittings and reuse them by following a straightforward procedure that requires a moderate amount of time and effort.

Can copper pipe be used for hot water?





Copper pipes are used in hot and water applications in many places. This piping system is a common one both in underground and above the groundwater systems. The major advantage of copper pipes is making multiple connections by a plumber. Example for multiple connections is sweat soldering and push-fit connections.

Can I get hot water from a cold water pipe?

If your forced-air heating system is running, the metal surface of the ventilation ducts could be warm to the touch. If your cold water pipe is in contact or close to the ductwork, then some of that heat could transfer to the water line.

Why can copper be used for both hot and cold water pipes?

Why is copper used for piping? Copper is durable and corrosion resistant. It can also withstand high temperatures — this is why it was so popular for the transportation of hot and cold water.

What pipes can you use for hot water?

CPVC pipes are an ideal choice for hot water plumbing. They are made after adding material that goes through extra chlorination process which gives CPVC higher quality.

What types of copper pipe can be used in a hot water system?





Type M Copper Pipe: Type M copper pipe is thinner than both type K and L copper pipe. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems. It can be used with sweat, compression, and flare fittings.

How long should copper pipes last in a house?

70 to 80 years

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. In most new construction, this is seldom a problem, but if you live in an old home you might want to see what pipe material your house has.

Can bacteria grow in copper pipes?

It is important to note that only dry copper surfaces are amazingly lethal to bacteria. The difference between dry and wet surfaces, such as copper pipes, is that only dry surfaces are inhospitable environments for bacterial growth.

What are 2 disadvantages to using copper pipe?

  • Copper Pipes Are Expensive.
  • Copper Piping May Add a Metallic Flavor to Water.
  • Copper Pipes Cannot Withstand Acidic Water.
  • Why are copper pipes used for hot water?



    Copper is non-permeable and doesn’t absorb any substances that it comes in contact with. Hence, the water supply stays protected. Unlike pipes made from iron water pipes, copper water pipes don’t corrode so easily. Most other materials will be corroded by whatever corrosion agent that they come in contact with.

    Why did they stop using copper pipes?

    Copper was the plumbing pipe of choice from the 1950s until 2000 and was widely used both in new construction and to replace the galvanized steel water supply pipes that had been the standard into the 1950s. But copper’s use has gradually faded, due to the introduction of PEX plumbing tubing.

    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 plastic water pipe better than copper?



    PROS: Resistant to corrosion, abrasions, and impact damages better than copper pipe because plastic doesn’t corrode. PVC pipe is thicker than copper which also helps with impact damages and abrasions. Less noise compared to copper piping, even with higher water velocities and speeds.

    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.
