How Does Slotted Drainage Pipe Work?

How Does Slotted Drainage Pipe Work

Slotted drainage pipe is designed with various slot openings to allow water enter or discharge while prevent other foreign particles getting into drainage system. Slotted drainage pipe can perfectly protect your projects by draining excess liquids.

How Deep Should Slotted Drainage Pipe be Buried?
How Deep Should Slotted Drainage Pipe be Buried
How Deep Should Slotted Drainage Pipe be Buried

In order to exert the best performance of slotted drainage pipe, the deep of slotted drainage pipe is better to keep at 12 to 18 inches, but sometime to maintain right slope, the depth may changed.

What is the Best Slotted Drainage Pipe To Use?

What is the Best Slotted Drainage Pipe To Use

Plastic drainage pipe is the best solution for drainage system, such as PVC, HDPE.

Compared to mental slotted pipe, plastic drainage pipe is immune to any weather conditions, hence there is no need to worry about maintain costs. What’s more, plastic slotted drainage pipe is lightweight to transport and install.

Which is Better PVC Slotted Drainage Pipe or HDPE Slotted Drainage Pipe?

Which is Better PVC Slotted Drainage Pipe or HDPE Slotted Drainage Pipe

Both PVC and HDPE are good materials to form slotted drainage pipe, but there are some differences between them.

  • PVC means vinyl polymer, and HDPE relates to polyethylene thermoplastic made

from petroleum. Both of them have unbeatable resistance to high temperature. But HDPE is proven to be more durable under harsh conditions like rain, stress or cold conditions.

  • HDPE slotted drainage pipe is more softer and easier to bent compared to PVC

slotted drainage pipe, hence it is widely used in conditions that has lower pressure, smaller bending radius. As a stronger and stiffer one, PVC slotted drainage pipe is suitable for direct burial conditions.

  • Basically, HDPE slotted drainage pipe is expensive than PVC slotted drainage pipe.

However, based on your needs, the price can be changed.

How Long Should Does Slotted Drainage Pipe Last?

How Long Should Does Slotted Drainage Pipe Last

Filson slotted drainage pipe is expected to last for at least 75 years, because of its reliable and durable quality.

But things may be changed according to real situation, including the materials, the types of liquids, the flow and soil, etc.

If you want a high performance and clean slotted drainage pipe, we recommend you to replace it at 50 years so the possibility of cracks, clogging or sub-efficiency can be avoid.
