According to Plumbingpoints, before purchasing pipes for underground water supplies, you have to consider a few things, like material, chlorine resistance, installation, and many more. Keeping those facts in mind, we have enlisted some of the best pipes used for water supply lines. These include…

1. PVC Pipes

PVC stands for Polyvinyl Chloride Pipes, usually used as a part of the toilet, sink, or shower drain line.  It has a plastic tubing system that is absolute for this type of usage and protects water from corrosion and dust better than other pipes. Apart from that, the PVC pipes are durable enough, and they last indefinitely unless they are at risk of some destruction.

The best part of the pipes is, they will be put up with high water pressure. For that reason, they are used in the main water supply line of a home. PVC pipes are comparatively lightweight than the traditional galvanized steel piping options; thus, you can efficiently work with them. These pipes hold smooth inner lining that safeguards against trash buildup and makes them more immune to obstructions.

Now come to the downsides of PVC pipes. PVC pipes come in limited sizes and are not equipped to withstand hot water and concerns over toxicity. PVC indeed has all the qualities set by the American National Standards Institute.  But it may produce polyvinyl chloride chemicals into drinking water that causes respiratory disease. For that reason, in some states, PVC pipes have been banned from transporting drinking water.

2. PEX Pipes

The other name of PEX pipes is cross-linked polyethylene, which means it is an inexpensive plastic tubing generally used for water supply lines. It is similar to PVC that prevents corrosion or rust from leaching into the water.

Many professionals prefer PEX pipes as they are satisfactorily flexible and easy to twist through basements, walls, ceilings, and even in crawl spaces.

Moreover, they are significantly robust to tolerate the water supplies’ pressure. Besides that, this type of pipe is color-coded for both cold and hot water, making it easy to specify for plumbers during the installation.

3. ABS Pipes

ABS means Acrylonitrile Butadiene Styrene, which is close to PVC pipes in nature but is easy to specify due to its black color. This type of pipe is flexible in cold temperatures that are mostly used for vent and drain lines. This kind of pipe is straightforward to install, but it can wrap because of direct sunlight. Aside from, compared to other types of pipes, they are noisier than other pipes and cause disturbance among some house owners.

4. Copper Pipes

It is one of the most well-known pipes in the plumbing industry for more than a decade. Copper pipes can last more than 50 years and are generally found in showers, tubs, sinks, and other fixtures in homes, whether old or new. These pipes are most popular among plumbers and new house owners because they are corrosion resistant and perfectly suited to maintain the quality of the water.

Copper pipes can endure extreme water pressure and are indulgent of both cold and hot water temperatures. They are environment-friendly as well because they can be recycled too.

There are some drawbacks of it that you should contemplate before purchasing. These kinds of pipes are so rigid: thus, plumber can’t use them in tough spaces. On top of that, Copper pipes are the most expensive, and r continues to rise. If you have a specific budget, we recommend you not to use it.

5. Cast Iron and Galvanized Steel Pipes

You’ll rarely find cast Iron and galvanized steel pipes in the new construction sites. They were mostly used in the early 20th century. But iron and galvanized pipes are still significantly durable and used for parts of the water distribution system today.

These pipes are usually used as sewer pipes or for other drainage purposes. However, they are still popular among house owners because they are heat-resistant and decrease the sound of moving water.

The drawbacks of the pipes are, they are flat-out to rust and corrosion. Over time, this will impact its ability to manage a clean water supply. However, these pipes have predominantly been replaced by PEx or copper pipes in residential plumbing repairs.
