What’s the difference between white PVC and black PVC?

ABS is always black while PVC is white- and easy way to see the difference quickly. PVC piping offers more flexibility, but ABS is a stronger piping and can resist a higher shock. For underground, ABS is great as it can handle extreme cold and can warp if it is in direct sunlight.

How deep do you bury drainage pipe?

I usually dig a trench about 12 to 14 inches deep for downspout drain lines. If the lot is fairly flat, the pipes will get deeper the farther they extend, as you should create 1/8 inch of fall for every foot the pipes run.

What type of pipe is used for downspout drainage?

Schedule 40 PVC pipeThe drainage pipe used for extending downspouts is non-perforated Schedule 40 PVC pipe with 4-inches-diameter. Some jobs will also require flexible drainpipe, which is invaluable for getting around obstacles or following uneven terrain.

Does PVC pipe get brittle with age?

PVC pipe can be used for most any drain, water, or ventilation application. Many homeowners believe PVC to be a maintenance-free product, however, which may or may not be accurate depending on its application. PVC can become brittle and crack when placed in a few scenarios for prolonged periods of time.

Does PVC pipe deteriorate in sunlight?

UV light radiation can cause portions of the outer shell of CPVC and PVC pipes to degrade slightly, but not significantly. … Once pipes are removed from the direct exposure, the ultraviolet rays no longer affect them. Long-term sunlight exposure can decrease the CPVC and PVC’s impact strength and resistance.

What type of PVC pipe is used for sewer lines?

PVC. The leading choice in residential drain lines over the past four decades, PVC is a light-colored, highly durable plastic that resists the elements and appears to outlast all other piping materials. PVC is made in several different grades: schedules 40 and 80 and chlorinated polyvinyl chloride (CPVC).

What is the best PVC pipe?

Schedule 40 is the most common PVC type. Schedule 80 PVC is thicker and stronger, which enables it to handle higher pressures. Usually, PVC is only used for cold water pipes since hot water can eventually break down the plastic material. It can also degrade when exposed to the heat and UV rays of the sun.

Reliability and safety should always be considered, as well as local, state, and national codes. Water filled pipe should be buried at least 12″ below the maximum expected frost line.

How long will PVC pipe last underground?

100 yearsThe Water Research Foundation reported that 100 years is a conservative estimate for a properly designed and installed PVC pipe. Dig-up studies on PVC pipe materials around the world report no degradation after decades of operational service.

Can I bury PVC pipe in concrete?

You can, but it would be wise to bury the pipe in sand or pea-gravel under the slab to be poured. Not a great idea to embed the PVC pipe directly in the concrete, because of the old (and well established reliable) saw “concrete cracks”.
