7 Ques about PVC Drainage Systems You may want to check!

Aug. 25, 2023


We are all familiar with PVC drainage systems when we talk about them. Every urban water conservation scheme in our daily routine uses PVC, which is a popular pipe material.
PVC may offer a high-quality, corrosion- and wear-resistant drainage environment as a drainage pipe, and it is also highly affordable. PVC pipes are more frequently found in municipal engineering drainage systems than other types of pipes in water supply systems.

You will probably have a lot of questions regarding the PVC drainage system. We're going to highlight seven typical about the PVC drainage system in this article.

Hope this article can be useful to you; let's look!

 Que 1Can pvc be used for drain pipe  
- Yes! 
PVC (polyvinyl chloride) is commonly used for drain pipes in residential, commercial, and industrial applications. PVC drain pipes are known for their durability, corrosion resistance, and ease of installation. They are often used to transport wastewater, sewage, and other types of drainage away from buildings and structures.

PVC drain pipes come in various sizes and types, including schedule 40 and schedule 80 PVC. Schedule 40 PVC is suitable for most residential applications, while schedule 80 PVC is thicker and more durable, often used in more demanding commercial or industrial environments.

When using PVC for drain pipes, make sure to follow local building codes and guidelines to ensure proper installation and adequate ventilation. PVC pipes should be properly sloped to allow for efficient drainage and prevent the buildup of stagnant water or clogs. Additionally, it's important to use appropriate fittings, solvent cement, and proper installation techniques to ensure leak-free and effective drainage systems.

Que 2What type of pvc is used for drains
For drains and wastewater systems, the most commonly used type of PVC is Schedule 40 PVC. Schedule 40 refers to the thickness and pressure rating of the PVC pipe. It is a lightweight and relatively cost-effective option for residential and some commercial drain applications.

For drains and wastewater systems, the most commonly used type of PVC is Schedule 40 PVC. Schedule 40 refers to the thickness and pressure rating of the PVC pipe. It is a lightweight and relatively cost-effective option for residential and some commercial drain applications.

Que 3Which pvc pipe is best for underground drainage

For underground drainage applications, Schedule 40 PVC is commonly used and is generally suitable for most residential and light commercial needs. It offers a good balance of durability, cost-effectiveness, and ease of installation. However, there are a few additional considerations to keep in mind when using PVC pipes for underground drainage:

Perforated PVC: In some cases, especially for subsurface drainage systems like French drains, you might consider using perforated PVC pipes. These pipes have small holes or slits that allow water to enter the pipe and be carried away. Perforated PVC is designed specifically for subsurface drainage and can help prevent waterlogging in soil.

Proper Slope: Regardless of the type of PVC pipe you use, it's crucial to ensure proper slope for effective drainage. The pipes should be installed with a gradual downward slope to allow water to flow freely. Local building codes often specify the required slope for different pipe diameters.

Backfill: When installing PVC pipes for underground drainage, proper backfilling is important. The area around the pipe should be filled with coarse gravel or similar material to aid in water drainage and prevent soil from compacting around the pipe.

Bedding: Providing a stable and supportive bed for the PVC pipe is important. A layer of sand or fine gravel underneath the pipe can help distribute the load and prevent damage.

UV Resistance: While underground, PVC pipes are generally protected from sunlight, which can degrade PVC over time. However, if the pipes will be exposed to sunlight for any period, consider using UV-resistant PVC or using pipe wraps to shield the pipes from UV rays.

Que 4What we need when we want to clean pvc drains

Cleaning PVC drains involves a combination of mechanical and chemical methods to remove blockages, debris, and buildup. Here's a step-by-step guide on how to clean PVC drains effectively:

Materials You'll Need:
  • Rubber gloves
  • Drain snake or auger
  • Plunger
  • Baking soda
  • Vinegar
  • Hot water
  • Bucket or basin
If the blockage is severe or if you're unsure about performing the cleaning yourself, it's best to contact a professional plumber to assess and address the issue.

Que 5Hows the different when Drainage pvc vs Corrugated?
1. Material:
Drainage PVC Pipes: These pipes are made of rigid PVC (polyvinyl chloride), which is a type of plastic. They come in various schedules (thicknesses) and are designed for carrying wastewater, sewage, and drainage away from buildings.

Corrugated Pipes: Corrugated pipes are usually made from a flexible plastic material, often high-density polyethylene (HDPE). They have a corrugated or ribbed design, which provides some flexibility while maintaining strength. These pipes are commonly used for drainage in landscaping, agriculture, and other outdoor applications.

2. Application:
Drainage PVC Pipes: These are typically used for indoor plumbing systems, including residential, commercial, and industrial applications. They are used for carrying wastewater, sewage, and other drainage away from toilets, sinks, showers, and other fixtures.

Corrugated Pipes: Corrugated pipes are commonly used for outdoor drainage applications, such as agricultural drainage, French drains, foundation drainage, and landscape drainage. Their flexibility and ability to bend make them suitable for use in uneven or changing terrain.

3. Cost:
Drainage PVC Pipes: PVC pipes can be more expensive than corrugated pipes, especially for larger diameter pipes used in indoor plumbing systems.

Corrugated Pipes: Corrugated pipes are generally more cost-effective, making them a popular choice for various outdoor drainage needs.

In summary, the choice between drainage PVC pipes and corrugated pipes depends on the specific application. Drainage PVC pipes are suitable for indoor plumbing systems, while corrugated pipes are commonly used for outdoor drainage applications due to their flexibility, cost-effectiveness, and ease of installation in various terrains.
