As a homeowner in Singapore, you must know about the different plumbing pipes available. Each type of pipe has its benefits and drawbacks, so selecting the appropriate one for your property is critical. This blog post will discuss the different plumbing pipes and what you need to know about them.

type of water pipe

PVC Pipes

Sinks, toilets, and shower drain lines are all PVC pipes (polyvinyl chloride). Because plastic tubing protects the water from rust and corrosion better than other pipes, it's perfect for this application. This feature also explains why PVC pipe is such a long-lasting material. Unless they are harmed, PVC pipes will endure indefinitely.

They are also suitable for PVC pipes. They may also serve as your home's main water supply line. It is also a lighter-weight material than galvanized steel pipe, making it easier to deal with. The smooth inner lining of PVC pipes prevents sand from building up and makes them more resistant to blockages.

PVC pipe has several drawbacks, including limited size options, a propensity to heat, and safety concerns. Although PVC pipes meet all ANSI requirements, there are worries that they may be contaminated with vinyl chloride chemicals, possibly resulting in respiratory and reproductive problems. Due to these worries, some states have prohibited PVC plumbing pipes from transporting drinking water.

PEX Pipes

PEX or cross-linked polyethylene piping is a low-cost plastic tubing frequently used for water supply lines. It also resists rust and corrosion from leaching into the water, like PVC pipes. PEX pipes are flexible and easy to weave through walls, ceilings, basements, and crawl spaces. They're also strong enough to endure the pressures of your water supply. Cross-linked polyethylene pipe is color-coded hot and cold water making it simple for plumbers to identify and organize on the job.

ABS Pipes

ABS pipes are black and resemble PVC pipes, although they are simpler to identify owing to their unique black hue. Acrylonitrile butadiene styrene is resistant to extreme cold. Drain and vent lines made of acrylonitrile butadiene styrene are the most frequent. ABS pipe is simple to put together; nevertheless, it may warp when exposed to direct sunlight. ABS pipes make more noise than other plumbing pipes, which irritates some homeowners.

Copper Pipes

Copper pipe has been a mainstay in the plumbing business for decades. Plumbing pipe comes in large diameters, is made of various materials, and may endure for 50 years. It's most commonly used in bathrooms, mainly showers, baths, and other fixtures in new and old homes. Copper pipes are famous among plumbers and homeowners since they are corrosion-resistant and help maintain water quality.

Copper pipes are heat-resistant and resistant to a wide range of water temperatures. It's also recyclable, making it more environmentally beneficial. There are a few things to consider. Because copper pipes are so strong, plumbers aren't able to work in confined spaces with them. Copper piping is also the most expensive form of plumbing pipe. When copper prices rise, so do the costs associated with any project that utilizes copper pipe.

Cast Iron and Galvanized Steel Pipes

Newer homes are generally built with a copper water line, but cast iron and galvanized steel pipes are rarely seen in current construction. In contrast, cast iron piping is quite robust and is still used in particular water supply systems today.

Pipes constructed of cast iron were frequently used in sewage or drainage systems. Their popularity was primarily due to their heat tolerance and the noise of flowing water's silence. Unfortunately, over time, cast-iron pipe rusts and corrodes. Copper or PEX pipes have replaced mainly these types of lines in household plumbing repairs.

PPR Pipes

There are many benefits to PPR pipes and PPR pipes fittings. The pipes' extremely low thermal conductivity makes them perfect for systems that serve both cold and hot water. Together, they and glass wool insulation systems are utilized in modern buildings to increase energy efficiency. It must be noted that only the PPR pipes with red lines can be installed for hot water use, and the blue ones are for cold water use.

Galvanized Pipes

Galvanized iron pipes were formerly employed in construction. However, owing to the accumulation of rust within the lines, it is currently used less frequently. Because of the tiny diameter, the rust accumulation narrows down the supply channel. You may get water flowing from faucets with traces of rust - owing to scales falling out of the pipe - which demonstrates that they are still functional if you have old and rusted galvanized pipes.

Pipes may be used to provide non-drinking water. If you have antique and rusted galvanized pipes in your garden, they're conceivable to leak. If you do not want to wait for the technician's arrival, get them fixed immediately by a professional.


As most of us know, lead poisoning may result in serious health problems such as kidney and nervous system damage, especially considering the Flint lead crisis. Any exposure to lead is inadequate for human health. As a result, you'll only find lead pipes in older buildings after 1950. Many more lead lines were available until 1950. Lead may be found in supply or drain pipes, which can cause lead poisoning. Lead drain pipe dangers are significantly lower than those of copper drain pipes. Nonetheless, water that travels through your lead drain pipes might eventually end up in personal sewer systems and local aquifers.

As soon as feasible, replace lead water supply lines. Plumbing professionals should also talk about lead drain pipes, which are frequently old and need to be replaced. You may use a home testing kit purchased at a home improvement store to check the purity of your water for lead. Alternatively, you could have your local plumber do this work for you.

Cast Iron Pipes

Bell-and-spigot pipes are often shaped like a bell with a stopper. These with threaded connections are more costly than bell-and-spigot versions, although they exist. These are larger than other pipes and are typically employed as the main pipe in underground installation and drainage systems, sewer systems, and drainage systems.

The most inexpensive ones, about 4 inches long and big enough for residential usage. Because of their colossal shape, cast iron pipes require adequate support when connecting them. Otherwise, pipe bursting will occur.

What Are the Various Types of Water Pipes Available?

The most frequent varieties of plumbing pipe in use today are copper, galvanized steel, polyvinyl chloride, acrylonitrile butadiene styrene, and cross-linked polyethylene. Chlorinated polyvinyl chloride is also utilized. PVC piping may be converted to this shape by exposing it to chlorine. This improves the material's temperature performance and resistance to fire and corrosion properties.

What Is the Most Acceptable Pipe for an Underground Water Line?

For an underground water line, you may utilize either plastic or PEX pipes. Both can be buried and support high pressure, although they are not resistant to rusting and corrosion. Copper plumbing pipes may also be used for underground infrastructure; they are rust-proof and leakproof. They are particularly vulnerable to certain soil qualities, however. Before beginning any project, it's critical to check with local building laws.

What Is the Best Piping for Plumbing?

In the majority of homes, PVC pipe is used for plumbing. It's inexpensive and available in a variety of connections and sizes. It's also an excellent choice for supplying hot and cold water.

Is PEX Better Than PVC?

PEX pipes, on the other hand, are more common among plumbers since they are flexible and straightforward to put in place. It doesn't require any glue, which might leak into the water and cause problems. PEX is also resistant to rust, making it ideal for connecting metal pipes.
