Yes. When plumbing with PEX, you can use stab-in or compression fittings to make the connections, but they’re too expensive to be practical on large projects. Connections for most PEX supply jobs require a special tool.

Can you use PEX A and B together?

There are two parts to this transition: the PEX-A MIP adapter and the PEX-B FIP adapter. These parts will thread together and allow you to join PEX-A to PEX-B. The PEX-A side will require an expansion ring while the PEX-B side requires the crimp ring.

Can hot and cold PEX lines touch?





Hot and Cold Water Lines Should Never Touch

The picture above is of PEX hot and cold water lines that have been run through the framing and are touching each other the entire way. This has passed the rough plumbing inspection and is ready for insulation and drywall.

Where should you not use PEX?

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 wrong with PEX plumbing?





PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.

Can you use SharkBite fittings on PEX A?

Identify the pipe material.

SharkBite brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and SDR-9 HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and SDR-9 HDPE. The PEX stiffener does not need to be removed for Copper or CPVC applications.

What is better PEX A or PEX B?

Bottom line, PEX A is more resistant to burst pressure than PEX B. PEX A’s expansive material can handle up to 500 PSI, which makes it reliable in extremely cold temperatures. Since PEX B is a more rigid material, it will not hold up as well in similar situations.

Does PEX freeze break?



A: No, PEX pipe is freeze-damage resistant, meaning the pipe will expand if frozen and contract to its original shape when thawed. PEX pipe is not freeze-proof, however, meaning that the water in the pipe can still freeze and block the flow.

Can PEX touch ductwork?

However, PEX cannot withstand a furnace flue’s/exhaust pipe’s temperatures, ensure PEX is not touching nor even within 2′ (my requirement) of that Ductwork.

How close can PEX fittings be to each other?

To support bare PEX, space hangers between 32 inches and 48 inches apart, depending on the applicable code.

How long will PEX piping last?



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.

How long do PEX connections last?

ASTM International, a standards organization, requires that the life expectancy for PEX pipe be at least 50 years. (Some PEX manufacturers offer a pipe life expectancy of more than 100 years.)

Is PEX safe 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 safe for drinking water 2021?

This provides confirmation the pipe does not leach harmful substances into drinking water and is safe for potable systems in healthcare facilities. From an installer standpoint, PEX provides installation efficiencies as well as safety on the job site.

Can I use blue PEX for hot water?



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. Plumbing code does not require the pipe color to match the type of water supply.

Is PEX plumbing better than copper?

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.

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.

Does PEX reduce water pressure?

It won’t affect pressure, but the volume is decreased. If you do a manabloc, it probably doesn’t matter much.

Does PEX need to be insulated?



Does PEX Pipe Need To Be Insulated? Yes, although PEX pipes can withstand freezing temperatures better than other pipe materials – but they are not freeze proof!

At what temperature will PEX burst?

Don’t place the blow dryer directly on the pipe, hold it a few inches away and test the pipe with your hands to feel if it’s thawed enough. But be aware that the general rule of thumb is that pex tubing can withstand temperatures of up to 200 degrees Fahrenheit.

Will PEX freeze in attic?

While PEX does not ordinarily burst in the cold, the water in the pipes can still freeze. It is important to insulate PEX pipe in an attic, particularly in cold-weather areas.
