What is the difference between red and green antifreeze? can i use green coolant instead of red.
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.
PEX without an oxygen barrier is designed primarily for use in potable water plumbing systems. 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.
Potential chemical leaching is another downside of PEX piping. Due to its chemical composition, the PEX pipe material may leach toxic chemicals including bisphenol (BPA), MTBE, tertiary butyl alcohol (TBA), and others.
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.
With a plumbing-pipe offering in sizes up to 3 inches, PEX is challenging traditional copper and CPVC materials for domestic water applications. … This provides confirmation the pipe does not leach harmful substances into drinking water and is safe for potable systems in healthcare facilities.
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. … PEX-B is a clear winner in terms of price vs. both other types.

Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home’s PEX water pipes, the result can be disastrous.
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
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.
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper’s intensive extraction and manufacturing process presents some environmental trade-offs.
Due to its flexibility, PEX has a small margin of expansion under the damaging pressure caused by ice formation. If the weather gets cold enough, PEX pipes can and will freeze like any plumbing. However, PEX may be less likely to rupture as a result of freezing.
The Viega PEX system uses the PEX-b tubing (although you could also use another brands PEX-a) and a pressed ring securing the PEX to the fittings.
The stainless steel Cinch Clamps are stronger than the copper Crimp Rings. I know this from personal experience after working with frozen water lines. When the fitted connection freezes with water in the line it will cause the copper Crimp Ring to expand just enough to cause a leak when it thaws.
There are two simple methods for identifying PEX pipe: Check the label. If you look closely at the pipe, you will see information printed on the side. PEX-A will clearly say PEX-A, while PEX-B will say — you guessed it — PEX-B.
The installer recommends replacing my copper pipes with PEX. … If so, you could get another 23 years out of your copper pipes and spare the cost to replace plumbing. If it’s a small area that’s leaking, you could just replace that section with either PEX or copper. Both types are interchangeable.
- PEX may leach BPA and other toxic chemicals. …
- PEX is extremely sensitive to UV light. …
- PEX can be damaged by chemicals and pests. …
- PEX can’t be installed in high heat areas. …
- PEX is semi-permeable, which means liquid can enter the pipe.
Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water.
Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.
Crimp fittings require copper or stainless steel crimp rings and a PEX crimp or clamp tool. … Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX. Crimp fittings are preferred for many applications since they are widely available and are the most affordable.
No. You should not use any type of adhesive material on PEX pipe as over time the adhesive material can interact with the PEX and leech into your water. You can use a heating strip wrapped around the pipe so long as it has no adhesive material.
We recommend you create a cheat sheet for your respective pipe sizes, so you don’t have to search for them later. For our example, our 1-inch pipe can have up to 30 fixture units, our 3/4-inch can have up to 14, and our 1/2-inch can have up to 4.
PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). OD of PEX, copper and CPVC pipe with the same size (CTS) is the same. This is why push fittings can be used with all of these pipes.
About the 1/2″ Red Pex Tubing – 5′ Length 1/2 Inch Pex Tubing, 5 Foot Length – Red Color. The tubing has a 1/2 Inch size and comes in 5 foot lengths which is great for smaller applications that require a shorter distance of tubing.
Rodents Chewing Through PEX Pipe is a common problem in our area. … Therefore, a rodent can, and will, gnaw through water pipes to get to food and water when they smell it. Pex Pipe and PVC are Malleable. Finding out you have rodents or other critters living in your house can be an unsettling discovery.
A: Oxygen barrier type PEX pipe has an external polymer coating called EVOH or “oxygen diffusion barrier” and it’s the type used for all standard closed loop heating applications, including floor heating, baseboard/radiator heating and snow melting.
PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.
If you are using PEX, you can run it through your attic. PEX will NOT burst unless you live in a place that gets like 50 below. And it does not freeze as readily as metal pipe.
Can pex pipes be used underground? – The answer is YES – It can be used underground. It should be buried below the frost line and best if bedded in sand or stone dust. The Advantages Of Using PEX Tubing are: It’s very flexible.
Most PEX pipes are reliable pipes. However, one brand in particular has routinely failed – Dura PEX piping, manufactured by CPI (bought out by NIBCO). Dura Pex (by CPI) is prone to cracking and probably has already caused you a lot of headaches (and bills for pipe fixes).
Hot and cold PEX water lines run through the same hole in a stud wall. … This is not a typical installation; both pipes should have their own holes to pass through the framing.
PEX tubing may be connected directly to residential electric tank or tankless (instantaneous) water heaters, if the local code and manufacturer’s instructions allow. When connecting PEX tube to gas tank or tankless water heaters, the tube must be kept at least 6 inches away from the exhaust vent of the heater.
As with PVC, PEX is rust-proof, infinitely durable and marked with identifiers along the exteriors of pipes. PEX’s purpose, however, is the opposite of PVC — whereas the latter is restricted to drain lines, the former is only used for incoming water lines.
– Compatibility with metal pipes. When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. … PEX plumbing pipes may contaminate your home drinking water, although this can be avoided if your plumber uses specially certified impermeable tubing.
PEX does leach small amounts of VOCs. Different brands cause different odors and leach different chemicals. The studies have not identified the brands by name. But they found variations even within each brand.
Copper pipes are probably the most traditional plumbing pipe used due to their extensive duration and reliability. They provide superior corrosion resistance, great material to be used for hot and cold water, and it can be managed easily.
While PEX pipes can and will freeze in cold weather, it withstands cold temperatures better than copper, PVC, or CPVC which is rigid and will burst easily. … As a general rule of thumb, if your PEX piping is traveling through interior walls or insulated exterior walls, you don’t need to insulate the PEX piping.
The maximum heat temperature of the PEX tube is 200 degrees. The maximum heat of the PEX can be up to 180 degrees. The PEX tubing has the highest temperature limitation listed in small prints.
PEX pipes and all underground piping should be buried at least 12” to 18” below the frost line to protect the pipes from freezing. The frost line refers to the furthest depth underground groundwater begins to freeze, also called the frost depth.
PEX pipe is made by a handful of companies, but the best version I’ve discovered so far is part of a system called ProPEX. It’s a proprietary brand of PEX connections and pipe invented by an international company named Uponor (uponor.ca) and based in Finland.
