PEX Plumbing Pipes

One of the newest and biggest innovations in plumbing pipe is PEX (cross linked polyethylene) piping. Created in the 1980's but not used until the late 1990's in home applications, it is considered by many as the best plumbing pipe option.

PEX Piping can be snaked through a house and bent through high-beams or placed around corners in ways no other types of plumbing pipe can be. It requires no adhesive and can withstand freezing conditions better than most other plumbing pipe types (except copper).

In most applications it is spliced into existing pipe (including copper), which makes it a viable choice for retrofitting old homes. Furthermore, there is no risk or known issues with using it for the transportation of drinking water, as seen with standard PVC piping.

PEX Piping Uses

- Retrofitting Older Homes
- Can Be Used For The Same Applications As Copper Piping
- In Tight Space Uses Where Corners and Angles May Cause Problems

Copper Plumbing Pipes

For over 60 years copper piping has been the standard go-to in homes. This is due to the durability and lifespan of copper piping. In most scenarios a copper pipe can handle extreme temperature fluctuation and is resistant to corrosion. Because copper is a solid metal it is safe to use for the transportation of drinking water and will not cause debris. Because of this, copper is typically used in some applications and not others and is considered to be one of the best types of plumbing pipes.

One of the major problems with copper piping however, is the cost. Copper tends to be one of the most expensive types of plumbing pipe.

Copper Piping Uses

- Drinking Water
- Refrigerant and Water Lines
- Applications Requiring A Tight Seal
- Service Lines That Run Underground

PVC Plumbing Pipes

Another option for plumbing pipe is PVC (polyvinyl chloride). PVC is most frequently used in homes built after the year 2000. It is versatile and extremely affordable, making it a great option for keeping the cost of repiping down.

PVC is great for home applications since it does not rust or corrode and will not need to be replaced unless it cracks or begins leaking. Another reason to use PVC pipes is that they require no welding or metal work. Finally, PVC is incredibly durable and will not bend under pressure, making it a great choice for high pressure water uses.

One of the main drawbacks of PVC piping, however, is that it cannot be used for hot water delivery. When exposed to the extreme heat of hot water temperatures, PVC piping will begin to warp and bend over time. In addition, PVC piping may also degrade or change in structure when it is exposed to UV light for long durations of time. Because of this, it is a great option for indoor and underground piping.

Another important point about PVC: it’s not rated for use with drinking water, due to the toxic levels of certain compounds found in PVC material.

PVC Piping Uses

  • Sink Drain Lines
  • Toilet Drain Lines
  • Shower & Bathtub Drain Lines
  • Main Water Supply Line
  • High Pressure Application

Another type of PVC pipe is CPVC pipe. CPVC has extra chloride added to its composition, which adds extra durability and will not degrade with liquids. This allows CPVC pipes to be used as a safe option for handling drinking water.

CPVC can be used for the same applications as copper piping, but is often considered a better option due to its insulation. This prevents energy loss in hot or cold applications throughout the house. Another added benefit of CPVC is that it’s more pliable than metal tubing, which allows for extra versatility.

CPVC Piping Uses

  • Hot and Cold Water Delivery
  • Drinking Water Delivery
  • Waste and Water Disposal

Are plumbing estimates free?

Plumbing estimates and on-site quotes should always be free and are really a mandatory requirement for many reasons. You should view any plumbing service that quotes you over the phone with caution, since that company will not be able to collect enough information to provide a truly accurate estimate.
