Since the 1960s, copper has been used for P traps because it is a very durable material. Even though other materials have been introduced since then, copper is still one of the best options because it can last for a long time without needing to be replaced. The main disadvantage of using copper piping is its high cost.

In addition, soldering and additional fittings are required to install it properly. Using copper for your P trap might save you money in the long term, even if it may cost more upfront since you won’t need to repair it as frequently. Copper is also a good choice because it is resistant to corrosion and can withstand high temperatures. When made correctly, a P trap made from copper can last many years without leaking or breaking. Copper is the way to go if you’re looking for a durable and long-lasting option.

PVC p trap

PVC is a common material used in P traps, and it comes in two sizes, Schedule 40 and Schedule 80.

  • Most residential fences are made of Schedule 40 PVC, with thinner walls and a lower price than other types.
  • PVC with schedule 80 walls is more expensive, durable, and expensive.

The American National Standards Institute (ANSI) maintains tables that describe the outer diameter of PVC pipes. The advantages and disadvantages of using PVC as a pipe material are compiled in the following table.

Pros

  • Resistant to rust and corrosion
  • Resistant to high water pressure
  • Low cost
  • Easy installation, no welding or metalwork
  • Versatile: multiple sizes and fittings
  • Strong and durable
  • Nonconductive

Cons

  • It cannot be used for hot water since heat deforms PVC.
  • UV radiation causes PVC to deteriorate; hence sunlight exposure is not permitted.
  • Not safe for drinking water.
  • Not recyclable.

PVC, or polyvinyl chloride, is a type of plastic frequently used in plumbing. It is solid and durable, making it an ideal material for drain lines. PVC can also be used for indoor P traps, underground plumbing, vent stacks, central water supply lines, and high-pressure piping.

PVC is also used for sewage drainage systems. One advantage of PVC is that it corrodes less than other metals. Another benefit of PVC is its connections with a wide range of piping, making it a flexible option for plumbing applications.

Chlorinated Polyvinyl Chloride Piping (CPVC)

cpvc p trap

CPVC stands for Chlorine-PVC Violet. It is a high-chlorine variant of PVC piping. Although standard PVC isn’t suitable for hot or drinking water, CPVC is. Copper pipes are rougher and make no sound when water flows through them, whereas CPVC pipes are smoother and produce fewer vibrations.

Besides being more flexible than metallic pipes, CPVC piping is insulated to avoid energy loss. It is fire resistant as well as smoke and heat resistant.

Pros

  • Water that may be drunk safely
  • simple to install
  • may transport hot water
  • more adaptable than PVC and aluminum pipe
  • PVC advantages with added durability
  • Fire resistant
  • Nonconductive

Cons

  • CPVC pipes split when frozen
  • Not recyclable
  • More expensive than PVC
  • The manufacturing process is highly polluting

Common uses for CPVC pipes include water and waste drains and hot and cold water supplies. Circulation systems (valves, fittings, and elbows) also commonly utilize CPVC pipe because it is flexible.

Its ability to resist heat without softening has made it popular among environmental engineers. It’s ideal for constructing tunnels under pesky roots or other barriers that would prevent the passage of sewage pipes through your property’s infrastructure.)

Galvanized Steel

galvanized steel p-trap

This product was formerly widespread, but because of its hazardous consequences, it has been abandoned:

  • Due to the zinc covering, internal corrosion occurs in pipes of tiny diameters.
  • It can get clogged over time
  • Corroded pipes can release lead
  • Water discoloration

Galvanized steel pipes are heavy-duty and can withstand a lot of wear and tear, making them ideal for drains that see a lot of use. However, because of their weight, they are only suitable for P traps, where the weight isn’t an issue.

These pipes were frequently used in greywater and non-potable water drains, as they can withstand high levels of stress without breaking. In addition, galvanized steel pipes are resistant to corrosion, which makes them ideal for use in drains that come into contact with harsh chemicals or other corrosive substances.

Stainless Steel

Stainless steel P trap

Stainless steel is a robust and durable metal that is resistant to corrosion. Because of this, it is an excellent option for plumbing parts, especially in locations with a risk of corrosion, such as along the coast.

The bulk of cast iron P traps is bell and spigot types, the most heavy-duty plumbing pipes. They’re highly resilient and may be used to replace portions of a cast iron piping system using PVC. Cast iron pipes, however, are rather hefty and need additional support during installation.

Cast iron pipes are frequently used in underground installations, such as significant pipes in drainage and sewage systems and water distribution systems.

Grey Plastic Polybutylene

ploybutylene p trap

Polybutylene piping (PB) is a type of grey plastic plumbing pipe commonly used in home construction from the 1970s to the 1990s. It is inexpensive and easy to install, but it is also prone to leaks.

Over time, the plastic pipes can become brittle and crack, allowing water to leak into your home. If you have PB piping in your home, it is crucial to have it inspected regularly by a licensed plumber. Any damage to your house should be fixed or replaced as quickly as feasible to stop additional harm.

High-Density Polyethylene (HDPE)

HDPE p trap

High-density polyethylene piping (HDPE) is a flexible material commonly used in various applications. HDPE offers excellent corrosion resistance and long service life, making it an ideal choice for many industries.

However, this superior performance comes at a price, and HDPE is typically more expensive than PVC. Despite the higher cost, HDPE is often the preferred material for demanding applications where corrosion resistance and long-term reliability are critical. In addition, HDPE is a recyclable material, making it an environmentally friendly option for many projects. When selecting piping for your next project, consider the benefits of HDPE to determine if it is the best choice for your needs.

Polypropylene (PP)

PP p-trap

Polypropylene P traps are rigid plastic pipes that are similar in many ways to CPVC pipes. Like CPVC, they are solid and durable, making them an excellent choice for plumbing and other applications.

However, polypropylene pipes are not combined with chemicals; heat is used to adhesive the mating ends. This makes for a stronger bond that is less likely to leak. In addition, polypropylene is resistant to various chemicals, making it an ideal choice for many industrial applications.

Consequently, polypropylene pipes have become increasingly popular in recent years as an alternative to traditional metal and PVC piping.

  • PP is frequently utilized in Europe but is not well discussed in the US.
  • PP is a long-lasting, human-safe, and ecologically beneficial substance.
  • The most significant disadvantage is a complicated installation procedure that needs specialist equipment.

PP trap is commonly used in hot and cold water supplies and drains.
