Is 1 2 PEX 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.
Should I use plastic or metal PEX fittings?
The basic fact is that plastic fittings is better and effective, unlike the brass PEX fitting. It is true that in areas where water is less acidic, brass fitting is better. But in areas where water is acidic or easily contaminated, plastic fittings are better.
Is PEX crimp better than 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.
Which is better PEX-A or B?
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.
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.
How many fixtures are on a 1/2 PEX water line?
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.
Can you reuse PEX crimp rings?
When done correctly, it’s possible to reuse PEX fittings after the copper crimp rings have been removed.
Is PEX good for plumbing?
PEX is regarded as a very safe product and is used in many domestic and commercial areas. It is cheaper and easier to install than copper plumbing. PEX is also not as susceptible to freezing temperatures and resists bursting. By avoiding the issues mentioned, PEX plumbing is very safe for installation.
What do you need to know about insulating PEX pipes?
How to Insulate Pex Remove moisture, dirt and oil from the surface of the PEX tubing with a clean rag. Align the slit side of a length of flexible closed-cell pipe insulation with the tubing. Push the insulation toward the tubing until it pops into place. Pull the ends of the protective tape — covering the inside faces of the insulation seam — to expose the adhesive.
Are PEX pipes good?
PEX is superior in many different ways and is valued for its cheap costs, ability to resist scale and chlorine and fit into a quicker installation process. Although it isn’t a great fit for outside use, PEX piping tends to be more resistant to freezing temperatures than copper piping.
Is PEX piping reliable?
PEX pipe is as reliable as iron and copper pipes, without the problem of metal corrosion creating pinhole leaks and fitting failures. An early concern with PEX pipes was inexperience among plumbers regarding installation and attempting to use improper or defective fittings.
