A Comprehensive Buying Guide

There is a variety of choices when you decide to get the best pipe for water for any project. However, you can’t find a one-size-fits-all solution when it comes to choosing the best material for an underground water pipe. Therefore, you should determine what you’re going to do with the pipe first. Thus, you can get the right one.

 

Factors include cost, durability, quality of water, environmental impact, and longevity when you decide to replace the pipe.

 

Materials

 

The material comes first in our minds when we talk about the quality of the underground water supply. Let’s see what are materials used to make the pipe for potable drinking water.

 

Galvanized Steel

 

They are generally made of steel which is galvanized with zinc coating to protect the pipe from rust and corrosion. Once, it was one of the widely used pipes for a variety of underground water projects. But it lost its position because of the time and labor required to install and cut and thread. However, they are still seen in heavy commercial water projects.

 

Copper

 

Another type of pipe is made of copper. They are mostly used for transmitting both cold and hot water. As well as, they are also applied for refrigerant lines in the HVAC system. They are liberal. You can use them for above-ground or underground water systems. Copper pipes can be affected sometimes by the soil and therefore they should be guarded with a protective sleeve in case of use under the soil.

 

A qualified copper can live up to 50 years or so. However, over time, they can thin out which can cause pinhole leaks. Now, several plastic pipes occupied the position of copper as it requires high labor and effort to cut and install. Consequently, some builders find relief in the alternative, especially in PEX.

 

PVC

 

Polyvinyl chloride is known as PVC in short. PVC is used in different types of plumbing projects from drainage to main lines. Along with that, for irrigation piping, home, pool, spas, or building missions, PVC is a good choice for many builders.

 

They mainly come in white but other color options are also available. The color and mark on the pipe will tell you what the pipe is for. For instance, the pipe with the black letter on the purple pipe is born to reclaim water.

 

CPVC

 

Another type of material CPVC is used to make plumbing pipes. It stands for chlorinated polyvinyl chloride that oft comes in cream-color or off-white color. They can survive temperatures up to 180-degree Fahrenheit (depending on the thickness), so you can use them for both hot and cold water.

 

CPVC comes with the same push-fitting as PEX and copper and with the same outside diameter as well. Experts say PVC and CPVC pipes can serve you for up to 75 years under healthy circumstances.

 

PEX

 

It is the most used type of pipe these days. It is the condensation of cross-linked polyethylene, sometimes called XLPEI. It is widely used because of its temperature-resisting capacity. You can use them for both cold and hot water in residential or commercial projects. They are most appreciated for the best output from the radiant floor heating system.

 

They are sturdier than copper and others giving the longevity of 50 years or so. Most builders now prefer PEX because of the low price and the long rolls of tubing that make them easier to transport. It is also greatly flexible and can be bent effortlessly minimizing the elbows and other fittings resulting in fast installation.

 

Installation

 

Installation remains another aspect of underground water pipes for any type of water project. You need to know to what extent your pipe is easy to join. Your connection should be secure so that you can get relaxed for the next period of changing or repairing the pipe.

 

Pipes are to be joined in many ways. But not all of them allow you do it conveniently. Pipes that can be joined with several tube connections are the most preferable. For example, a crimp connection that is done with a crimp tool, rings, and fittings or the cinch connection. The compressed PEX fittings are also a highly effortless installation method.

 

Chlorine Resistance

 

Along with keeping the flow of water seamless and uninterrupted, the water should be safe for drinking and transmitting through the pipe. Pipes that are guarded with chlorine resistance can ensure. SharkBite U870B300 PEX Pipe comes with this feature to ensure safe potable drinking water.

 

Price Range

 

Price is always a crucial factor in the quality product. However, you shouldn’t think that all quality product is pricy. You can avail of the right one even in a cheaper price range. So, don’t be so obsessed with the quality that you forget to consider the price. The best pipe for potable drinking water or wastewater comes within 50 dollars which goes up to 120 dollars or more.

FAQ – Best Water Pipe for Underground

 

Underground water lines are essential to ensure a consistent water supply in your home. Whether you’re building a new home or remodeling the existing one, you need to make sure that all your plumbing needs are met. 

 

You’ll need to choose a durable and long-lasting material that will stand the test of time. Let’s discuss the best water pipes that you can use for underground water lines.

 

Which Pipe Is Best for Underground Drainage?

 

The answer to this question depends on the soil and water composition of your area. Generally, PVC pipes are most commonly used for underground drainage as they’re cost-effective, corrosion-resistant, and lightweight.

 

They’re also durable and can last up to 100 years. However, PVC pipes aren’t very flexible and require fitting and elbows during the digging and laying water lines process.

 

The following are three subtypes of PVC that can also be used for underground water lines.

 

CPVC

 

CPVC stands for chlorinated polyvinyl chloride and it’s commonly used for hot water supply. That’s because it can withstand extremely high temperatures as compared to PVC.

 

Additionally, chlorinated polyvinyl chloride pipes can also work efficiently under high pressures. 

 

UPVC

 

UPVC stands for unplasticized polyvinyl chloride, and as the name suggests, pipes made of this material have no plasticizers. They’re more durable than both PVC and CPVC and commonly used for large-scale applications.

 

They come with a smooth inner coating, can withstand high temperatures and pressures, and are resistant to chemical erosion.

 

PVC-O

 

PVC-O are molecularly oriented PVC pipes. The production process of these pipes converts the amorphous structure UPVC into a layered structure.

 

It enhances the benefits that UPVC offers, such as flexibility, stiffness, an unsurpassed balance between strength, recyclability, preservation of water quality, and corrosion resistance.

 

PVC-O pipes make for a great option when it comes to underground lines for drinking water. The best thing about these pipes is that they’re 100 percent recyclable.

 

Which Pipe Is Best for an Outdoor Water Line?

 

Stainless steel, copper, and galvanized pipes make for the best options for outdoor water lines. That’s because they’re weather-resistant and strong enough to bear chemical and mechanical stress.

 

Galvanized

 

Galvanized pipes are typically made of steel and iron and have a zinc coating, making them rust and corrosion-resistant. These pipes are also commonly used for underwater water lines because of their durability, reliability, and long lifespan of 80 to 100 years.

 

Additionally, they also have low to no maintenance requirements and you can use them for more complex and longer waterlines.

 

Stainless Steel

 

Stainless steel pipes make for the best option in terms of non-corrosiveness and durability. That’s because these pipes are made with an alloy of chromium and iron. They can also resist high temperatures, making them ideal for underground pipelines.

 

Stainless steel pipes are most commonly used in areas, such as coastlands, that are susceptible to corrosion. It’s important to note that stainless steel pipes are very expensive and won’t be the best option for people on a tight budget.

 

Copper

 

Copper is a durable material that’s resistant to rusting and leaks, making it a good choice for underground pipelines. However, the biggest drawback of this material is that it’s sensitive to soil containing high amounts of Sulphur or lower pH value.

 

In addition, it’s also expensive and doesn’t perform great when it comes to flexibility. So, if there are obstacles, like a wall or a big rock, copper pipes won’t make for the best option. While this issue can be resolved using pipe elbows, it’ll cost you more.

 

Is PEX Pipe Good for Underground?

 

Yes, PEX pipes make for a great option for underground water lines. These pipes are made of melted HDPE polymers, making them highly flexible, durable, and resistant to chemical corrosion. In addition, they can also withstand a high amount of pressure and high temperatures. 

 

Pipes made of PEX make for a great option for areas that have too many obstacles to move around during the process of digging and laying water lines.

 

That’s because they won’t need too many elbows and fitting, thanks to their flexibility. Not only does it make the installation process easy but it also makes them cost-effective. 

 

The only downside of PEX pipes is that they’re not as long-lasting as most other options. They have a lifespan of about 50 years.

 

Which PVC Pipe Is Best for Underground Drainage?

 

We have discussed four different PVC types, including simple PVC, CPVC, UPVC, and PVC-O. The best option among these types is PVC-O because it’s more durable, impact-resistant, flexible, and crack-resistant than other types.

 

In addition, PVC-O is also lighter than other times which makes the installation process easy, lowering the installation cost. However, PVC-O pipes aren’t very common, and the upfront cost of these pipes can be high depending on your area. 

 

Therefore, it might not be the best option for you if you’re on a budget. In such a case, you can opt for UPVC as it’s also a good option for underground drainage and performs better than PVC and CPVC in terms of durability and strength

 

However, when it comes to high temperatures, CPVC performs better than UPVC. That’s because it can withstand higher temperatures (of up to 200 degrees Fahrenheit) than UPVC, which is rated for up to 60 degrees Fahrenheit.

 

What Should You Consider While Buying Pipes for Underground Water Lines?

 

The following are the most important factors that you should consider while buying pipes for underground water lines.

 

Soil Composition

 

Soil can contain different types of substances and some of them can be damaging to pipes made of a certain material. For example, if you live in an area with soil containing high amounts of Sulphur or higher pH value, you’ll need to avoid pipes made of copper.

 

Water Composition

 

The minerals that water carries can cause corrosion in pipes, accelerating the wear and tear process. Understanding the composition of water in your area will allow you to choose a material that will not deteriorate quickly.

 

PSI Rating of Pipes

 

PSI (Pound per Square Inch) rating shows the maximum amount of pressure that pipes made of a certain material can withstand. If the water pressure gets higher than the PSI rating of pipes, the risk of pipe bursting will become higher.

 

While the water pressure can be adjusted using a valve or pump, you want to make sure that you choose pipes that can withstand the highest amount of pressure, which can run through them. It’ll allow you to eliminate the risk of pipe bursting.

 

Final Words

 

As you can see, there are multiple materials that you can use for underground pipelines. You’ll need to take into account the soil and water composition of your areas to choose the best water pipes for the underground.

 

We recommend you consult with experts to determine the type of pipe that’s best suited for your area before making your buying decision.
