SDR 35 thick-wall PVC piping is the best material for drainage system piping. Compared to the black, corrugated drain lines you're probably used to, our thick-wall PVC doesn't bend, sag, leak water, or get crushed. When properly installed, PVC drain lines will deliver decades of performance.
Standard schedule 40 PVC will work fine, the size depends on how much water you expect to pass through the pipe over a period of time, but commonly it's around 4'' for buried underground drains.
PVC-U is the most common PVC type for pipes and fittings including transportation of drinking water, soil and waste, sewage and underground drainage and industrial applications. Pipes and fittings made of PVC-U have many benefits.
Schedule 40 PVC pipes are typically used for water supply lines, sewer lines, and drains. Why Use 1 1/2 Schedule 40 PVC Pipe?
PVC Pipes. PVC is the material of choice for drainage experts, builders and homeowners because of its cost and ease of use. It's very lightweight and malleable, making it the easiest to install, but it also has a good strength that makes it very durable.
PVC pipe schedules can range from 10 to 160 but schedules 40, 80, and 120 are the most commonly used for underground applications. The higher the schedule, the thicker the pipe wall. Different-schedule pipes may have the same exterior diameter but have distinct interior diameters.
Cast Iron
Despite the heat resistance and noise-dampening properties of cast iron, it's not as suitable for underground water supply as newer materials. Cast iron is not resistant to corrosion, which can compromise the quality of the water supply and damage the integrity of the piping, leading to leaks and breaks.
Schedule 40 rigid PVC conduits are for aboveground use indoors or outdoors exposedto sunlight and weather, and for underground use by direct burial or encasement in concrete. Specifically marked for underaround use are suitable for useunderground only by direct burial or encasement in concrete.

The Water Research Foundation reported that 100 years is a conservative estimate for a properly designed and installed PVC pipe.
PVC pipes are the best option for most drainage projects due to their strength, durability, and corrosion resistance. They are also relatively inexpensive and easy to install. PVC pipes are strong enough to withstand the weight of soil and water and are not easily damaged by roots or debris.
Here is where the flexibility of SDR 35 outweighs the strength of Schedule 40. SDR 35 will bend with the shifting and settling. Having a higher flex tolerance means less breaks from the soil conditions.
You may want to opt for rigid PVC which is less likely to clog, and make sure your gutter drains are at least 12 inches deep or more to avoid damage from freezing and heavy traffic. To keep water away from your foundation, create a gutter drain that is at least 4 to 6 feet long, as well.
Most of the time, you will be urged to install PVC sewer pipes for most drainage projects because the material is strong, durable, resistant to corrosion, and cost-effective.
Schedule 80 pipe has thicker walls and is able to withstand higher PSI (pounds per square inch). This makes it ideal for industrial and chemical applications. To give you an idea of the size difference, 1” schedule 40 PVC pipe has a . 133” minimum wall and 450 PSI, while schedule 80 has a .
SDR 35 thick-wall PVC piping is the best material for drainage system piping. Compared to the black, corrugated drain lines you're probably used to, our thick-wall PVC doesn't bend, sag, leak water, or get crushed.
Schedule 40 PVC is commonly used for drinking water. The “Schedule 40” part defines its strength and thus basically its pressure handling capability. Manufacturers require manufacturing and handling processes to satisfy “potable water” designation for their PVC products.
All pipes should be laid in a trench that is 300mm wider than the pipes themselves. In addition to this, all plastic pipe runs need to be laid on a 10mm layer of pea shingle or fine gravel. This will provide a base for larger grade material and backfill to be placed on top later.
You are probably most familiar with schedule 40 PVC pipe. It's the white pipe you see used for drainage around buildings, and it can be found in local hardware stores. This pipe is best suited for drainage, irrigation, and other cold water systems.
The National Electrical Code (NEC) recommends a minimum burial depth of 18 to 24 inches for Schedule 40 PVC conduit. Local electrical codes may require depths up to 30 inches depending on applications and exposures.
Buried installations: Schedule 80 PVC conduit is more resistant to crushing and damage from soil and rocks than Schedule 40 PVC conduit, making it a better choice for buried installations.
PVC and CPVC have more strength and durability than PEX because they are more rigid, making them better suited to outdoor applications where the piping may be subjected to trauma.
How long will PVC pipe last underground? The lifespan of PVC pipes is estimated to be around 100 years, though this isn't an exact figure because PVC pipes have only been used in the U.S. since the 1960s.
Bedding - Pipe embedment shall be crushed limestone #57 for sewers, from four (4) - inches below the pipe barrel to 12-inches above the pipe barrel for PVC pipe and to the springline for RCP pipe.
