Every time you spot a purple pipe, you can be sure recycled water is flowing through it! Similarly, when you see a purple recycled water sign, it shows that recycled water is used at that location for a specific purpose.
Purple pipe systems provide recycled water for industrial, landscape irrigation, or other demands not requiring potable-quality water, via a dedicated delivery system that is completely separated from the system used to deliver potable water.
Purple pipe means recycled water.
Product Details. SharkBite Reclaimed Water PEX is cross-linked polyethylene tubing for gray water, rainwater harvesting and reclaimed water systems only. Manufactured with a purple color background, the tubing meets color code requirements of national and state code bodies to clearly identify reclaimed water lines.
Lilac Striped Pipe, also known as Purple Stripe Poly is used for recycled water and non-potable water applications. The benefit of using a lilac stripe is so that after installation, the pipeline is easily recognisable for what service it is providing.
Blue pipes are used for potable or drinking water. Green pipes are sewer and drain lines. Lavender or purple pipes carry reclaimed wastewater that undergoes filtration and disinfection treatment before being reused for irrigation.
Significantly, HDPE pipes are durable and flexible and can be used for more than 50 years without any complications. On the other hand, polyethylene or PE pipe is the most common and widely used plastic globally. It's a common polymer used for packaging mainly plastic bags, films, bottles and geomembranes.
Copper pipe prices fluctuate wildly, since this is a commodity dependent on market forces. Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold. These colors are just for your convenience.
When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won't corrode. - Price. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)
PEX plumbing lacks versatility because of its sensitivity to light. PEX cannot be taken anywhere outside the house where it is directly exposed to UV for a long period. The synthetic material of the pipes can slowly disintegrate due to the light of the sun.
Schedule 40 PVC is usually white in color and has thinner walls, thus can handle less pressure than it's counterpart. Schedule 40 PVC pipe works best for low water pressure applications. By contrast, Schedule 80 PVC is usually gray in color and has thicker walls; therefore, it can handle higher water pressures.
Purple pipe origin story: the true tale of how IRWD set a standard for recycled water. Throughout the nation and around the world, purple pipes pulse with water that has gone down drains and been treated for reuse in landscaping, agriculture and commerce.
Blue. Many water systems use blue PVC as their main pipe to transport water, ensuring that it is safe and potable.
Purple is the national color for pipes that carry clean, non-potable water such as groundwater or rainwater. The pipes are made out of purple-colored PVC so they are not confused with pipes carrying treated, drinkable water.
Pipe Color Code Standards
Following pipe color-coding is extremely helpful for obtaining crucial information about a pipe's contents. If color codes are ignored, employees are at a higher risk of causing an accident that may result in physical harm as well as facility damage.
It doesn't corrode, is flexible and easy to install, and can be used with many different connections. But PVC can't handle extreme heat, it melts and could potentially cause negative health impacts. Because of this, using PVC pipes for your drinking water supply is not advised.
Of course, PEX piping does carry some disadvantages. It will crack and break apart under the influence of strong UV rays (making it unsuitable for most outdoor use). Plumbers require specialized tools to cut and join this type of modern pipe. Additionally, disposing of used PEX pipe sometimes proves problematic.
Copper Pipes
Copper pipes remain popular among plumbers and homeowners alike because they are corrosion-resistant and best suited to protect the quality of the water. Copper pipes are able to handle high water pressure and are tolerant of both hot and cold water temperatures.
A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time. Although the taste and odour usually dissipate with use, water from two of the PEX types still had an unpleasant smell and taste after a year.
Plastic pipes, such as CPVC, and PEX are pipe materials that are safe for drinking water.
In most cases, PEX is extremely durable and lasts up to 50 years or more. PEX piping is also less likely to crack or break than metal pipe because it does not expand and contract as much when heated and cooled.
Some of the most common ways for HDPE pipes to break are ductile overload, non-ductile or pinhole cracks, and oxidative degradation [52] ; for example, leaks at CI pipe sleeve connections; HDPE tee cracks, connector cracks, and pipe cracks; PVC pipe cracks, pipe corrosion, and tee leaks [49].
Cost: PVC pipe is generally less expensive than HDPE pipe, which can make it an attractive option for applications with tighter budgets. Rigidity: PVC pipe is more rigid than HDPE pipe, which makes it a good choice for applications that require high stiffness, such as water mains or sewer lines.
Overall PVC Pipe price is quite low. HDPE pipes can be installed in Open Trench, Drop Burial, Directional Bore, and Horizontal Bore ways. Trained personnel and energy intensive equipment are needed for installing HDPE fittings. HDPE pipe price can be higher.
