What do the different colors of PEX pipe mean?

The Colors of PEX Tubing. It is available in red, blue, and white to make classification of water lines easier (red for hot, blue for cold, white for supply lines or single-color systems). The color of PEX does not change any of the tubing’s ratings.

There are no performance differences between red, white, blue and white PEX and all are intended for use in potable water systems. The colors can be used to easily distinguish between hot and cold distribution lines.

One may also ask, why is PEX plumbing bad? PEX failures Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.

Can I use white PEX for hot and cold?

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

Can you use PEX pipe for air line?

PEX is designed for liquids and shouldn’t be used for air lines. The tubing is “likely” ok, but the fittings are not, AFAIK. There is a similar product out there, however, that is designed for air.

Should I insulate PEX pipe?

Pipe insulation is a prudent step to take. Not only does insulation promote energy efficiency, but it can also reduce potential problems with moisture and condensation. That’s because PEX pipes—basically a type of plastic—are physically different from other common piping materials.

Is PEX safe for drinking water?

The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.

Can you use orange PEX for drinking water?

SharkBite PEX Tubing is an excellent flexible water pipe tubing product for plumbing, radiant, and hydronic systems. Designed for use on hot and cold potable water lines, Orange PEX tubing is commonly used for radiant floor and hydronic heating applications.

What is the best type of PEX to use?

PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant. Both types of tubing come in three colors—red, white, and blue—in diameters ranging from 1/4-inch to 3 inches.

How do you connect PEX pipe?

Cut the PEX tubing. Slide the PEX crimp ring and over the tubing approximately 2″ past the end. Fully insert the PEX fitting into the PEX tubing so that the fitting’s shoulder touches the tubing. Position the PEX crimp ring 1/4”-1/8” from the end of the tubing. Open the PEX crimp tool’s jaws.

How do I know what size PEX pipe to use?

In general, the greater the distance from the manifold to the fixture, the wider the PEX tubing should be. A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line.

What is the difference between PEX and SharkBite?

Easy to join: With PEX, you do not need to learn how to sweat joints. You can use the SharkBite system, or you can purchase a crimping tool that uses either copper or steel rings that tighten the PEX onto brass fittings. Low cost: PEX is substantially cheaper than copper pipe.

What is the difference between PEX Tubing and PEX pipe?

PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. First and foremost is a high rate of chemical leaching – from 50% to over 200% higher than PEX-B (2), which is a major concern for plumbing applications.

Can you crimp PEX?

PEX Crimp Fittings Crimp fittings require copper or stainless steel crimp rings and a PEX crimp or clamp tool. Some manufacturers use O-rings on their metal fittings (manufactured to ASTM 2434 standards) to make the seal with the tubing. Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX.
