What size PEX should I use for a shower?
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.
Look for a maximum recommended lengths specification on the PEX packaging..
Which PEX is best for drinking water?
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).
Why is PEX Pipe bad?
But not enough is known about their possible health hazards, and a growing number of studies suggest that some plastic pipes leach harmful chemicals and accumulate heavy metals like lead. … They found that PEX pipes released more odors and leached more chemicals compared to polypropylene.
How long does PEX 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.
What are the disadvantages of PEX?
PEX Plumbing DisadvantagesPEX 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.
Why is PEX banned in California?
It was banned by California’s Building Standards Commission because there was a concern that some chemicals may leak from the pipe into the water. So, the authorities of California banned the PEX thinking that it may cause unnecessary exposure to chemicals or carcinogens which may lead to dangerous effects.
What is the flow rate of 1/2 PEX pipe?
At a design velocity of 8 feet per second (fps) in a ½” PEX system, water velocity will reach at least 12.7 fps and as high as 19 fps, depending on the type of fitting used. This excess velocity can create turbulent zones in the pipe.
Is 1 2 PEX big enough for shower?
As long as the supply lines for the shower tie into a 3/4″ line, 1/2″ will be fine. I use a Delta shower faucet that already has pex adapters made into the valve body, no threading or sweating, just crimp and you’re done. … When you connect the shower head to the Delta valve, use the “tub” outlet to get the maximum flow.
Is PEX safe for drinking water 2020?
Researchers have found 158 compounds in drinking water associated with plastic pipes, and a recent study on PEX discovered highly variable impacts on tap water quality, taste, and smell. Testing your water for plastic chemicals that may be leaching into your water is the best way you can protect yourself.
Does PEX reduce water pressure?
PEX plumbing systems don’t allow the water pressure to drop.
Can PEX water pipe used outdoors?
Can I use PEX pipe outside? PEX pipe is not approved for outdoor applications and is not approved for continuous UV exposure. PEX pipe should not be stored in direct sunlight.
Can I run 3 4 PEX to shower?
3/4″ pex is somewhat larger than 1/2″ copper, and 3/4″ copper is probably a good size for a bathroom group. If the pressure drops on the cold side (sink and someone flushes the toilet), that may be enough with 1/2″ line to cause a pressure balance valve to throttle the hot side while it’s also feeding the shower.
Should I use PEX A or PEX B?
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.
What is the safest pipe for drinking water?
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.
How do I know what size PEX pipe to use?
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.
