Answer
It was discontinued due to reports of pipes rupturing and flooding homes and businesses between 1978 and 1995. Polybutylene (PB) pipe is a grey plastic tubing that was commonly used as a water-supply plumbing pipe during the years 1978 to 1995.
It’s also important to understand what grey PVC pipe is used for?
Polyvinyl Chloride (PVC) — Another material that is becoming increasingly popular for modern plumbing system pipe, PVC is a white or grey pipe that is used for high-pressure water, most commonly as the main supply line into the home. The fact that it is less flexible than PEX means that it is less suitable for use in tiny interior areas.
Therefore, the issue arises as to what is the difference between grey and white PVC pipe?
The types of fittings available for each, on the other hand, varies. White PVC pipe fittings are often tiny and have tight bends, making them ideal for water flow. Grey PVC pipe fittings are often huge, with wide curves many centimetres in length, which makes them ideal for passing wire through them. Grey PVC fittings often fail to withstand pressure.
Second, what exactly is grey PVC?
PVC pipe is available in two different schedules: schedule 40 PVC pipe and schedule 80 PVC pipe. Schedule 40 PVC is often white in colour, while schedule 80 PVC is typically a dark grey in hue (they can also be found in other colors). Their most significant distinction, though, is in the way they are constructed. Schedule 80 pipe is constructed with a thicker wall than standard schedule pipe.
Is it possible to glue grey PVC on white PVC?
Gray (Electrical) PVC is not pressure rated, whereas white (water) PVC is rated. White PVC is softer than grey PVC, which allows it to bend more easily. Gray uses a one-step clear PVC cement that will not leave blue or read stains, which is important because it will be visible for a long time. (Please keep in mind that you can use clear cement on white for non-pressure applications.)

Which is more durable, Schedule 40 or Schedule 80 PVC?
Schedule 80 pipe has thicker walls and can withstand greater pressure than Schedule 40 pipe. Consequently, it is well suited 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 .
Is it possible to use plumbing PVC for electrical work?
PVC for electrical applications is not intended to be subjected to high pressures, such as those found in water lines, and it is not rated for use with high-pressure air. Plumbing PVC, on the other hand, should not be used for electrical conduit applications because it does not perform well in the presence of ultraviolet radiation and has a reduced rigidity.
What do the different colours of PVC pipe mean?
What colours are used for PVC Pipe? Blue: Potable Water| White: Irrigation and Water. Green: Sewer. Purple: Reclaimed Water.
What’s the difference between electrical PVC and plumbing PVC?
As far as the standards are concerned, there is a difference. “Electrical” PVC supposedly has stiffeners (to give it strength ) and is sunlight resistant. “Plumbing” PVC relies, in part, on the water inside for strength, and is not expected to be exposed to sunlight.
Which is stronger ABS or PVC?
PVC is more flexible than ABS, but ABS is stronger and more shock resistant. ABS is better at handling severely cold temperatures, but it can warp with exposure to direct sunlight. PVC is thought to be better at muffling the sound of running water. In most North American markets, the two types are priced similarly.
What does Schedule 40 mean?
Nominal Pipe Size. Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – “2-inch diameter pipe, Schedule 40”).
Can you use white PVC for electrical?
Since, in the listings, white plumbing PVC is NOT listed as an electrical raceway, it is not suitable for use as one.
What is the difference between black PVC and white PVC?
The two most common types of plastic pipe, Acrylonitrile Butadiene Styrene (ABS) and Poly Vinyl Chloride (PVC), have small differences depending on the use, but the main difference is that ABS pipe contains BPA while PVC does not. ABS is always black while PVC is white- and easy way to see the difference quickly.
What is GREY pipe?
It was discontinued owing to allegations of pipes rupturing and flooding homes and businesses between 1978 and 1995. Polybutylene (PB) pipe is a grey plastic tubing that was frequently used as a water-supply plumbing pipe between the years 1978 to 1995.
What is the difference between conduit and PVC?
PVC pipe and PVC conduit have different uses. PVC pipe is used primarily in plumbing and other pressurised systems. PVC conduit is used primarily in electrical systems. PVC pipe thus is used to carry water, while PVC conduit typically works as housing for wiring.
Can I glue Schedule 40 PVC to schedule 80?
Because schedule 40 PVC and schedule 80 PVC pipe have the same outer diameter, you can use schedule 40 PVC fittings with schedule 80 PVC pipe and vice versa. If you’re using the PVC pipe and fittings for industrial or chemical applications, you probably need to use schedule 80 PVC.
What is difference between schedule 40 and 80 PVC?
Schedule 40 and Schedule 80 pipes have the main difference of sizing and diameter. A schedule 80 pipe has a thicker wall even though its exterior diameter is similar to a schedule 40 pipe. Having the same outside diameter is possible because the extra thickness of a schedule 80 PVC is inside the pipe.
What is the difference between PVC and CPVC?
The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. PVC comes in nominal pipe sizes only, while CPVC is available in both nominal pipe sizes and copper tube sizes.
What is PVC DWV?
If you’ve been in the market for PVC pipe and fittings you may have come across something called DWV. DWV parts look very similar to standard white schedule 40 PVC pipe and fittings. Instead, DWV pipe and fittings are made to handle a different class of uses – Drain, Waste, and Vent (hence the name DWV).
