When you lay your PVC pipe, the rows of holes should always be facing the downward position. You want to keep the water level in your French drain as low as possible at all times, and you can't achieve this if the holes are facing upwards or sideways.


Where does drain tile go? What is Drain Tile? Drain tile is a perforated pipe that allows water to enter into the pipe. It's installed at the base of a foundation. Water in the soil flows through washed gravel on top of the pipe and is carried away from the foundation where the pipe exits the ground.

why does drain pipe have holes?

With the perforations facing down, the primary function is collection and distribution. Even when placed in a ground gutter as described above, the pipe fills with groundwater more quickly. When more water enters one area than another, it flows to another area of the pipe and drains away.

How do you put in a perforated pipe? Here's how to do it: Dig a trench along the outside of your footing. Lay the pipe on the virgin soil. Cover the pipe with at least 12 inches of washed gravel. Lay filter fabric over the gravel to prevent any soil from clogging the pipe. Back-fill the foundation with top soil back to its original grade height.

when should you use a perforated drain pipe?

If you are creating a new garden landscape, make sure that you install a good drainage system. Hence, use perforated pipes to absorb all the excessive water and drain it out of the way. By installing the pipelines in the ground, you can also collect the rain water into a reservoir and then use it for irrigation.

What is perforated drain pipe? When it's installed correctly, a perforated drainage pipe is an effective solution to problems with standing water or excessive ground water near a building's foundation. Drainage pipes are commonly used to move rainwater from gutters away from a house or to drain wet areas in low spots of the yard.

should I use solid or perforated drain pipe?

In general terms, whether using corrugated or sewer and drain pipe, perforated pipe is used for subsurface drainage and solid pipe is used to convey water from surface and/or subsurface drainage systems.

What type of pipe is used for downspout drainage? PVC pipe

Do I need gravel for solid drain pipe?

1 Answer. What does the gravel provide: The gravel helps allow you to build the drainage slope for the pipe and provides a back-up drainage medium for leakage. The gravel will allow the water to drain away from the pipe and down the path of least resistance in the direction of the pipe to the outfall.

Should I use PVC or corrugated pipe for drainage? Pros of solid PVC pipe: Durability: This type of pipe is much more durable than corrugated pipe - it isn't penetrable by roots and is simple to unclog. Smooth walls: The walls of PVC pipe are smooth, so it is less likely to clog or to catch debris that slows water flow.

How do you align PVC pipe?

When gluing PVC pipe together, dry assemble the pieces first to make sure they align right, then draw matching lines on both the pipe and fitting at each joint with an indelible marker. Disassemble the pipes and fitting, apply glue to each joint, and align the marks when reassembling for a perfect fit.

Does a French drain need to be sloped?

A French drain needs a slope of no less than 1%. That means from the highest point of the drain field all the way to the drain exit, the system should slope at least 1 inch for every 8 feet of length.

Can you use corrugated pipe for drainage?

One of the most common pipe materials used to create a French drain is plastic because of its durability. There are two frequently chosen pipe variations: corrugated and PVC. Both are lightweight, but corrugated pipe can be flexible, while PVC is stronger and more rigid.
