PEX tubes range in diameter from 3/8-inch to 1-inch for residential applications. For adequate water flow, it’s a good idea to install 1/2-inch or 3/4-inch PEX for your main lines. The standard when replacing old water supply lines with PEX is to use the same size.

Why is PEX plumbing bad?
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.
Is PEX a bigger than PEX B?
PEX A uses an expansion-style fitting. These fittings are much larger in diameter the PEX B fittings, and require an expansion tool.
What is the most commonly used PEX fitting?
Crimp style fittings are the most common and affordable type of PEX fittings and can be found in majority of supply houses, home improvement stores and online stores. Brass PEX crimp fittings are manufactured to ASTM F1807 standard.
What is the difference between PEX A and PEX B pipe?
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.
Can mice chew through PEX pipe?
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.
Is PEX OK for drinking water?
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.
Is PEX crimp or clamp better?
If you are looking for a fast and more secure connection that will stand the test of time, crimp tools are your better option. But if you want more flexibility without working more, go for PEX clamps.
Is red and blue PEX the same?
Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water.
What brand of PEX is best?
The Engel method or PEX-A is known as the best type of PEX due to its exceeding that of all international standards set for performance. For example, Sharkbite invented a push-fit fitting which utilizes the consumer to connect PEX tubing without the need for any tools.
What is better crimp or cinch?
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.
Where is PEX not allowed?
PEX can’t be installed in high heat areas. You can’t install PEX in high heat areas like near recessed lighting. This also means you can’t connect PEX directly to a hot water heater, but you can use a connecting material to do this.
What is the best way to connect PEX tubing?
The most common connection method used in PEX installation is the “Crimp” method. This process involves sliding a ribbed fitting into the PEX tube and crimping a seal ring around the connection point. These rings are typically made of copper, but may be found in plastic as well as brass.
Why would you choose PEX over copper?
Why most People prefex PEX Tubing over Copper – there is a less risk of leaks with PEX Tubing. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. PEX Tubing is cheaper because it takes much less labor to install. PEX Tubing is quickly becoming the industry standard.
Can PEX pipes freeze and burst?
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.
Can you use SharkBite on PEX type A?
SharkBite brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and HDPE.
